RapidConnect C-Series CST Armoured Fibre Optic Cable provides heavy-duty protection for direct-burial, underground and industrial networks. Corrugated steel tape armour helps resist rodents, crushing forces and impact, while dry water blocking protects the loose tube cable core against moisture migration. Available with OS2, OM3 or OM4 fibre in configurations from 2 to 96 fibres.
CST Armoured Fibre Optic Cable provides heavy-duty mechanical protection for underground, direct-burial and industrial fibre infrastructure. Specifically, the RapidConnect C-Series combines corrugated steel tape armour, dry water blocking and a durable outdoor cable construction. As a result, these protective layers help defend critical optical fibres against rodents, crushing forces, impact and demanding underground conditions.
Underground fibre networks face risks that standard outdoor cables may not adequately address. For example, rodents can penetrate polymeric jackets, while rocks, ground movement and construction activity can place damaging pressure on the cable. Furthermore, moisture can enter through a damaged sheath and migrate along the cable core.
Therefore, organisations should select underground fibre cable according to the installation risk, not simply the required fibre count.
The RapidConnect C-Series supports telecommunications backbones, industrial facilities, utility networks, regional infrastructure, mining projects and other applications where cable damage could cause significant operational disruption. Moreover, customers can select OS2 Singlemode, OM3 Multimode or OM4 Multimode fibre in configurations from 2 to 96 fibres.
In addition, the C-Series can incorporate a blue nylon outer jacket and an optional black polyethylene sacrificial sheath. Consequently, the final construction can address rodent exposure, termite activity, abrasive pathways and other environmental risks.
However, the correct cable selection requires more than armour alone. Instead, designers must also consider installation tension, bend radius, pathway capacity, water management, electrical conditions, joint placement and long-term maintenance.
Therefore, Anderson Corporation can help customers specify the correct RapidConnect C-Series construction for their underground fibre projects.
Underground installation protects fibre optic cable from direct sunlight, wind and many above-ground activities. However, placing a cable below ground does not remove physical or environmental risks.
Instead, underground cables may face:
A lightweight outdoor cable may perform well inside a clean and controlled conduit pathway. Nevertheless, it may not provide enough protection for direct burial or high-risk underground infrastructure.
For this reason, the RapidConnect C-Series places corrugated steel tape around the protected cable core. Consequently, the armour creates a strong physical barrier between the optical fibres and the surrounding environment. As a result, the cable gains greater resistance to rodents, crushing forces and localised impact.
The C-Series suits projects that require:
Most importantly, the C-Series gives infrastructure owners another way to reduce avoidable physical failures. Although no cable can eliminate every possible hazard, a steel-armoured construction can substantially improve protection in demanding underground environments. Therefore, the C-Series provides a strong option when the cost of network failure outweighs the initial cost of additional cable protection.
CST stands for Corrugated Steel Tape.
During manufacture, the cable producer forms steel tape around the cable core in an overlapping arrangement. In addition, the manufacturing process corrugates the tape. Consequently, the armour can provide mechanical strength while retaining enough flexibility for transportation and installation.
The corrugated profile performs an important function. For example, a completely rigid steel tube could provide strong mechanical protection, but installers would struggle to bend, drum and route it. By contrast, corrugated steel tape creates a practical balance between strength and flexibility.
The CST layer does not transmit network traffic. Instead, it protects the cable’s optical transmission components. Specifically, the internal loose tubes hold the fibres, while the steel armour and external jacket shield those tubes from the installation environment.
Many standard underground cables use polyethylene jackets. Certainly, polyethylene provides useful protection against moisture, abrasion and environmental exposure. However, a polymeric jacket alone does not create the same physical barrier as steel armour.
Therefore, CST cable serves a different purpose from standard outdoor fibre. In particular, it focuses on heavy mechanical protection, rodent resistance and long-term underground survivability.
Every layer within the RapidConnect C-Series performs a specific role. Therefore, the cable achieves its overall performance through a coordinated construction rather than one isolated material.
A typical C-Series cable includes:
The precise construction may change according to fibre count, fibre category and project requirements. However, the core design principle remains consistent. Specifically, the C-Series places strong mechanical protection around a dry water-blocked loose tube optical core.
The optical fibres carry data through the network. Accordingly, customers can select OS2 Singlemode, OM3 Multimode or OM4 Multimode fibre according to the required transmission system.
Loose tube construction allows the fibres to sit within protective tubes rather than bonding them tightly to the cable jacket. Therefore, the design helps isolate the fibres from some mechanical and thermal forces that affect the overall cable.
Nevertheless, the cable construction cannot compensate for an unsuitable fibre category. Instead, designers must match the fibre type to the active equipment, transmission speed, wavelength and link distance.
Colour-coded loose tubes organise and protect the fibres. In addition, the colour sequence helps installers identify fibres during jointing and termination.
C-Series constructions from 2 to 72 fibres use six elements. Meanwhile, the 96-fibre construction uses eight elements.
Depending on the required fibre count, the cable may contain a combination of fibre-bearing tubes and fillers. Specifically, these fillers maintain the intended cable geometry when the design does not require every position to contain fibres.
As a result, the cable retains a balanced construction across different fibre counts. Furthermore, this controlled arrangement supports consistent cable handling and fibre identification.
The central strength member provides longitudinal stability and supports the loose tubes around the cable centre. Furthermore, it helps the cable manage tensile forces during installation.
However, the strength member does not remove the maximum pulling-tension limit. Therefore, installers must control the hauling load and apply force through an approved pulling method.
Dry water-blocking materials help restrict water movement along the cable core.
When water contacts the superabsorbent material, the material swells. Consequently, it helps contain moisture near the point of entry instead of allowing it to migrate freely along the cable.
In addition, dry water blocking creates a cleaner working environment than a heavily flooded cable core. For example, installers do not need to remove large quantities of filling compound when preparing the cable for jointing.
However, dry water blocking does not make the complete installation waterproof. Therefore, installers must still seal cable ends, joint enclosures, pits and building entries correctly.
Corrugated steel tape defines the C-Series construction.
The steel layer wraps around the protected cable core and creates a strong mechanical barrier. Therefore, it improves resistance to rodent attack, crushing forces and localised impact.
In addition, the corrugations allow the armour to move as the cable bends within its specified radius. At the same time, the steel layer maintains greater resistance to penetration than a polymeric jacket alone.
Consequently, CST armour suits underground infrastructure where physical protection represents a major design requirement. Moreover, the armour can improve the cable’s ability to survive demanding installation and operating conditions.
The external jacket protects the armour and internal cable components from the surrounding environment. Depending on the selected construction, the C-Series can use a blue nylon jacket that supports termite resistance and reduces hauling friction.
Furthermore, the jacket protects the steel layer from direct exposure. Therefore, installers should preserve its integrity throughout transportation, hauling and placement.
Although the steel armour provides substantial protection, installers should never treat the outer jacket as expendable. For example, deep cuts or abrasion can expose the underlying materials and reduce the cable’s long-term environmental protection.
Customers can specify an additional black polyethylene sacrificial sheath over the blue nylon jacket.
Specifically, this extra layer protects the underlying nylon against abrasion and incidental installation damage. For example, it may provide valuable protection when installers need to haul the cable through long, abrasive or uncertain conduit pathways.
However, the sacrificial sheath increases the cable diameter and weight. Therefore, designers must confirm conduit capacity, bend management, hauling load and drum logistics before selecting it.
Rodents can cause serious damage to telecommunications cables.
For example, rats, mice and other animals may gnaw cable jackets while nesting, investigating materials or maintaining their teeth. Once a rodent penetrates the outer jacket, it may reach the underlying cable components.
Sometimes the damage creates an immediate fibre failure. However, the initial attack may only weaken the cable. Subsequently, moisture, movement or continued rodent activity may cause an outage.
An underground cable fault can involve far more than fibre repair. For example, the network owner may need to locate the failure, arrange excavation, manage traffic, open the route, install replacement cable, complete fibre jointing and test the restored link.
Consequently, the total repair cost can substantially exceed the original price difference between standard and armoured cable. Therefore, designers should consider rodent exposure before installation rather than after the first failure.
The corrugated steel tape within the C-Series creates a powerful physical deterrent. While the product name uses the established commercial term “rodent proof,” the technical description should focus on strong rodent resistance.
After all, no responsible cable manufacturer should imply that one layer can guarantee protection against every animal, installation condition or type of damage.
Actual performance depends on:
Therefore, designers should take a system-wide approach. For instance, the cable may resist rodent attack, but animals could still enter pits, enclosures, ducts or buildings through unsealed openings. Consequently, the complete pathway requires appropriate protection.
Crush resistance describes the cable’s ability to tolerate compressive force without unacceptable internal damage.
Underground infrastructure can expose cable to pressure from soil, backfill, rocks, ground movement and external loading. Furthermore, poor installation can create concentrated pressure points along the route.
The RapidConnect C-Series provides:
The short-term figure applies to temporary loading. By contrast, the long-term figure accounts for sustained pressure.
This distinction matters because a cable may tolerate a high temporary force but respond differently when pressure remains for months or years. Therefore, designers should consider both values when assessing an underground route.
The steel armour helps distribute external pressure around the cable. Consequently, less force reaches the loose tubes and optical fibres.
Nevertheless, the crush rating does not justify poor civil construction. Instead, installers should provide suitable bedding, controlled backfill and protection from sharp objects.
In addition, the route design should address vehicle crossings, structures and other areas with elevated loading. As a result, the complete pathway can support the cable rather than relying entirely on the armour.
Impact damage occurs when a concentrated force strikes the cable.
For example, rocks, tools, machinery or careless drum handling can place substantial force on a small cable area. Although a standard polymeric jacket may resist minor abrasion, it may provide limited protection against a sharp or concentrated impact.
The corrugated steel tape adds a harder barrier around the cable core. As a result, it can absorb and distribute more of the impact before the force reaches the loose tubes.
This protection becomes particularly important during:
However, steel armour does not make the cable indestructible. For instance, heavy excavation equipment can still crush, cut or deform it.
Therefore, network owners should combine armoured cable with accurate route records, marker tape, warning systems and controlled excavation procedures. In addition, they should update route records whenever contractors alter or extend the network.
Direct burial places the cable in the ground without a continuous conduit surrounding it.
This installation method can reduce conduit costs and simplify some long-distance routes. However, it also places greater responsibility on the cable construction and civil design.
A direct-burial cable must tolerate ongoing contact with the underground environment. Therefore, the specification should consider:
The RapidConnect C-Series suits direct-burial and other demanding external applications where the project requires greater mechanical protection.
However, direct-burial capability does not mean contractors can place the cable in an unprepared trench. Instead, they must control the complete installation environment.
For example, appropriate bedding helps prevent rocks or debris from creating concentrated pressure. Likewise, warning tape and route markers help reduce future excavation risk.
Furthermore, designers must consider cable separation, route changes, joints and building entries before installation begins. Consequently, route planning should form part of the cable-selection process.
The applicable standards, project specifications and legal requirements also remain important. In particular, the Australian Communications and Media Authority explains that registered cablers must understand and follow the relevant Australian cabling standards, including AS/CA S009 where it applies to customer cabling work.
Installers can also place CST armoured cable inside underground conduits.
At first, adding steel armour inside a duct may appear unnecessary. However, conduits do not eliminate every physical threat.
For example, a conduit may:
Therefore, CST armour can add another level of protection when the network carries critical services or the pathway presents uncertain risks.
Nevertheless, not every conduit route requires heavy steel armour. For instance, a clean, secure and well-designed pathway may support a smaller cable.
For compact conduit applications that do not require steel protection, the RapidConnect Mini Loose Tube Fibre Optic Cable may provide a more efficient construction.
Ultimately, the project risk should determine the choice. Therefore, designers should not automatically select the strongest or smallest cable without assessing the route.
Industrial sites often place communications networks near vehicles, machinery, civil works, processing equipment and changing ground conditions.
Although optical fibre does not suffer from electromagnetic interference in the same way as copper conductors, the cable still faces mechanical risks. Therefore, the external cable construction remains critical.
The C-Series can support backbone connections between:
Industrial networks often carry operationally important data. Consequently, a cable failure may affect production, monitoring, security or control systems.
In addition, the cost of failure may include labour, lost output, emergency repairs and safety-related delays. Therefore, project teams should include potential downtime when comparing cable constructions.
CST armour can provide valuable protection where the route crosses active work areas or locations subject to ongoing maintenance. Furthermore, its crush resistance can strengthen cable protection in areas with higher mechanical exposure.
Mining and resources projects can expose fibre infrastructure to difficult physical conditions.
For example, routes may encounter heavy machinery, abrasive materials, ground movement, moisture and repeated construction activity. Furthermore, remote locations can make fault repair slower and more expensive.
A steel-armoured loose tube cable can provide a strong option for fixed underground backbone infrastructure in these environments. In particular, the C-Series supports projects that prioritise mechanical protection and underground survivability.
However, the standard C-Series will not automatically suit every mining application. For instance, underground coal mines, hazardous areas and specialised industrial facilities may impose additional fire, mechanical, electrical or regulatory requirements.
Therefore, project teams should review the complete specification before choosing the cable. Anderson Corporation can then assess the environment and determine whether the standard C-Series suits the application or whether the project needs a specialised construction.
Utilities and telecommunications providers often expect underground fibre routes to operate for decades.
These networks may support:
A single cable may connect several downstream systems. Consequently, one physical failure can disrupt a much larger network.
CST armour improves the physical resilience of the cable. However, the wider system must also include appropriate redundancy, spare fibres, accessible joints and accurate records.
For example, a highly protected cable may still create an operational weakness if every service depends on one route. Therefore, designers should consider route diversity alongside cable protection.
Ultimately, resilient infrastructure requires both durable cable and sound network architecture. Moreover, network owners need suitable maintenance and restoration plans.
Corrugated steel tape and Glass Reinforced Plastic armour both increase cable protection. However, the two systems address different priorities.
The RapidConnect C-Series uses metallic steel tape and focuses on heavy-duty underground mechanical protection.
By comparison, the RapidConnect GRP Armoured Rodent Proof Fibre Optic Cable uses non-metallic GRP armour. Therefore, the G-Series may suit environments where the project requires an all-dielectric construction.
| Consideration | CST Armoured C-Series | GRP Armoured G-Series |
|---|---|---|
| Armour material | Corrugated steel tape | Glass Reinforced Plastic |
| Metallic components | Yes | No metallic armour |
| Primary position | Heavy-duty underground protection | Non-metallic rodent protection |
| Electrical conductivity | Conductive armour | All-dielectric armour |
| Earthing assessment | Required where applicable | No steel armour to earth |
| Key selection driver | Mechanical protection and underground survivability | Dielectric protection and rodent resistance |
Neither system provides the best answer for every project.
For example, the C-Series may suit a direct-burial industrial backbone where crush resistance represents the leading concern. Conversely, the G-Series may provide a better solution near electrical infrastructure where designers want to avoid metallic armour.
Therefore, customers should compare the complete installation requirements rather than only the rodent-protection claim. In addition, they should account for pathway design, earthing and expected mechanical loads.
The corrugated steel tape conducts electricity.
Consequently, designers and installers must consider bonding, earthing, electrical separation, induced voltages and lightning exposure.
The optical fibres do not conduct electrical current. However, the cable does not qualify as all-dielectric because it contains steel armour.
This distinction becomes important near:
In these situations, the project engineer should assess the metallic armour before approving the cable. Furthermore, the installer should follow the project’s documented bonding and earthing requirements.
Where the project requires a dielectric construction, the GRP Armoured G-Series may provide a better option.
Likewise, designers should not use the C-Series as a substitute for aerial cable. Instead, they should consider the RapidConnect ADSS Fibre Optic Cable for pole-to-pole deployment. After all, ADSS uses a self-supporting aerial construction and belongs to a separate infrastructure category.
Rodents do not represent the only animal-related threat to underground cable.
For example, termites can attack some polymeric jacket materials, especially in areas with significant termite activity. Even when the initial damage does not break the fibres, it may reduce the cable’s environmental integrity.
The C-Series can incorporate a blue nylon outer jacket that supports termite resistance.
In addition, nylon creates a relatively low-friction hauling surface. Therefore, it can reduce friction between the cable and conduit during installation.
However, the nylon must remain intact to deliver its intended protection. For instance, deep cuts, scratches or abrasion can reduce its effectiveness.
Consequently, installers should use suitable rollers, bell mouths, hauling eyes and pathway preparation. They should also inspect the jacket during and after installation.
Some nylon-jacketed cable designs can develop wrinkles when the cable bends. Specifically, movement between the nylon and the underlying sheath may create these irregularities.
Wrinkling can make hauling more difficult and reduce the consistency of the protective jacket. Therefore, the C-Series uses a bonded sheath design that helps keep the nylon stable.
As a result, this construction allows the cable to remain comparatively flexible while maintaining a consistent external surface.
Nevertheless, installers must still follow the specified minimum bend radius.
The C-Series requires:
For example, a cable with a 14.9 mm outside diameter requires a minimum radius of approximately 447 mm while under load. After installation, the minimum radius reduces to approximately 224 mm.
Importantly, these figures describe radius rather than diameter. Therefore, pits, enclosures and route transitions must provide sufficient space for the complete bend.
The optional black PE sacrificial sheath protects the blue nylon jacket against abrasion and incidental damage.
For example, the additional layer may help when installers haul the cable through a long conduit containing rough surfaces or multiple entry points.
The sheath increases the nominal cable diameter by approximately 2 mm:
In addition, it increases the nominal cable weight:
Therefore, customers should not add the sheath automatically.
Instead, designers should compare the additional protection against its effect on:
Where abrasion presents a significant risk, the additional protection may justify the larger size and weight. However, a protected and low-risk pathway may not require the extra layer.
Water does not normally interrupt transmission through an intact optical fibre. However, it can damage the surrounding cable system.
For example, water may enter through:
Once inside, moisture can travel through spaces in the cable. Consequently, it may affect a greater length than the original damage point.
The C-Series uses dry water-blocking materials to restrict this movement. Specifically, the materials swell after contact with water and help contain it.
Furthermore, dry water blocking simplifies cable preparation because installers do not need to remove large quantities of filling compound.
Nevertheless, water blocking provides a secondary defence rather than a replacement for sealing.
Therefore, installers should:
Together, these practices help protect the entire optical system. Moreover, they reduce the likelihood that a minor sheath breach will develop into widespread moisture damage.
The C-Series supports OS2 Singlemode, OM3 Multimode and OM4 Multimode fibre.
The correct choice depends on the network speed, transmission distance, wavelength, active equipment and future capacity requirements. Therefore, designers should select the optical fibre as part of the complete transmission system.
OS2 Singlemode commonly supports telecommunications backbones, industrial networks, campuses, utilities and long-distance connections.
It can carry signals across long distances when paired with suitable optical equipment. Furthermore, OS2 provides a strong migration path for future network speeds.
Standard OS2 C-Series product codes include:
| Product code | Configuration |
|---|---|
| CS2-06 | 6-fibre OS2 C-Series |
| CS2-12 | 12-fibre OS2 C-Series |
| CS2-24 | 24-fibre OS2 C-Series |
| CS2-36 | 36-fibre OS2 C-Series |
| CS2-48 | 48-fibre OS2 C-Series |
| CS2-72 | 72-fibre OS2 C-Series |
| CS2-96 | 96-fibre OS2 C-Series |
Add /SS to the product code when the project requires the optional sacrificial sheath.
For example, CS2-24/SS identifies a 24-fibre OS2 C-Series cable with the additional sheath.
OM3 Multimode may suit shorter enterprise, campus or industrial backbone links.
However, designers must confirm that the proposed speed and distance remain within the relevant optical application requirements. In addition, they must account for connector and splice losses.
OM4 Multimode provides greater modal bandwidth than OM3. Therefore, it can support longer distances for some high-speed multimode applications.
Nevertheless, fibre category alone does not determine performance. Instead, connector loss, splice loss, wavelength, transceiver type and link budget also affect the result.
Accordingly, Anderson Corporation can confirm multimode availability and product coding for each project.
The following specifications provide a general guide to the RapidConnect C-Series.
| Technical characteristic | 2–72 fibres | 96 fibres |
|---|---|---|
| Number of elements | 6 | 8 |
| Tube or filler diameter | 2.1 mm | 2.1 mm |
| Nominal cable diameter | 14.9 mm | 15.9 mm |
| Diameter with sacrificial sheath | 16.9 mm | 17.9 mm |
| Nominal cable weight | 190 kg/km | 220 kg/km |
| Weight with sacrificial sheath | 240 kg/km | 275 kg/km |
| Maximum installation tension | 2.5 kN | 2.5 kN |
| Short-term crush resistance | 6.0 kN/100 mm | 6.0 kN/100 mm |
| Long-term crush resistance | 3.0 kN/100 mm | 3.0 kN/100 mm |
| Bend radius under load | 30 × cable OD | 30 × cable OD |
| Bend radius without load | 15 × cable OD | 15 × cable OD |
| Installation temperature | 0°C to +50°C | 0°C to +50°C |
| Transport and storage temperature | –20°C to +70°C | –20°C to +70°C |
| Operating temperature | –10°C to +70°C | –10°C to +70°C |
Cable designs may evolve over time. Therefore, customers should confirm all critical specifications before ordering. In addition, they should identify any project-specific requirements during the quotation process.
The C-Series supports a maximum installation tension of 2.5 kN.
However, installers should treat this figure as a limit rather than a target. Instead, a well-planned installation should keep the actual hauling force comfortably below it.
Several factors can increase tension:
Therefore, long or complex routes may require a formal tension calculation.
In addition, installers can use a dynamometer or tension-limiting winch to monitor the load. Most importantly, they should apply pulling force through an approved hauling arrangement rather than the optical fibres or loose tubes.
Heavy-duty construction does not protect cable against every handling error.
Therefore, installers should keep drums upright and use equipment suitable for their weight and dimensions. In addition, they should never drop drums or allow them to roll without control.
Before hauling begins, the installation team should confirm:
The drum should rotate freely while the cable leaves it in the intended direction. Meanwhile, rollers should prevent contact with sharp edges.
After installation, the team should retain enough cable at joints and termination points for preparation and future maintenance. Furthermore, installers should reseal any cable end that remains exposed.
The surrounding route strongly influences long-term cable performance.
For direct burial, contractors should remove sharp rocks and debris before placing the cable. Subsequently, suitable bedding and controlled backfill help distribute pressure more evenly.
For conduit installations, contractors should check:
For example, proving the conduit before cable delivery can prevent expensive installation delays.
Furthermore, each transition into a pit, building or enclosure must maintain bend radius and protect the jacket against abrasion. Therefore, route inspection should occur before the contractor commits the cable to the pathway.
Loose tube cable normally requires suitable joint enclosures, splice trays, pigtails and termination hardware.
During preparation, the technician must remove the external layers without damaging the loose tubes. In addition, the technician must handle the cut steel tape carefully because its edges may become sharp.
Furthermore, the project’s electrical design should define how installers manage the metallic armour.
Good jointing practice includes:
Moreover, the enclosure must secure the cable mechanically. Otherwise, movement or pulling forces may transfer to the spliced fibres.
Testing confirms both optical performance and installation quality.
Therefore, the project should define the testing regime before installation begins. Depending on the application, the contractor may need to complete:
An OTDR can identify splices, connectors, bends and breaks along the route. However, technicians must interpret the trace correctly.
In addition, launch and receive fibres may help measure the first and last connectors.
By contrast, optical loss testing directly measures total end-to-end attenuation. Therefore, contractors should not assume that an OTDR replaces a light-source and power-meter test when the specification requires both.
Finally, the network owner should retain baseline test records. As a result, future technicians can compare later measurements with the original commissioning results.
The C-Series and W-Series serve different environments.
The C-Series uses a loose tube, steel-armoured construction for heavy-duty underground protection.
By comparison, the RapidConnect Indoor/Outdoor Fibre Optic Cable uses a tight-buffered construction for suitable transitions between outdoor pathways and indoor premises.
Choose the C-Series when the project prioritises:
Alternatively, consider the W-Series when the project prioritises:
Therefore, neither cable acts as a direct substitute for the other. Instead, the pathway, fire requirements, termination method and mechanical risk should determine the selection.
Cable selection forms only one part of a resilient fibre network.
Therefore, a long-life underground system should also consider:
Additional fibres often represent a small proportion of the total installation cost. After all, the project may already include trenching, conduit, hauling, jointing, traffic management and mobilisation.
Therefore, spare fibres can provide cost-effective future capacity. For example, they may support expansion, redundancy, temporary restoration or new services.
Similarly, accessible joints can simplify maintenance. Even the strongest cable provides limited value if every joint sits in an inaccessible or permanently flooded location.
Consequently, the best result comes from treating the cable, route and network architecture as one infrastructure system. Moreover, designers should consider future maintenance before finalising the original route.
Eligible C-Series installations can form part of the RapidConnect 25-Year Enterprise Cabling Infrastructure System Warranty.
However, the warranty program covers a complete registered cabling system rather than an isolated cable purchase. Therefore, product selection, installation, testing and documentation requirements may apply.
Customers should contact Anderson Corporation during design or procurement if they intend to register the project.
Early confirmation helps customers:
Consequently, customers should not assume warranty coverage solely because they purchased RapidConnect cable. Instead, they should confirm the program requirements before installation begins.
A clear cable specification reduces ambiguity and helps suppliers quote the correct construction.
At a minimum, the project should identify:
For example, a basic specification may read:
RapidConnect C-Series CST armoured loose tube fibre optic cable, 24-fibre OS2 Singlemode, with corrugated steel tape armour, dry water-blocked construction and blue nylon outer jacket, suitable for the nominated underground installation.
Where the project requires the sacrificial sheath, the specification should state that requirement clearly.
However, a generic description cannot replace a complete engineering review for a critical or complex route. Therefore, customers should provide the route conditions and project constraints when requesting a quotation.
Before ordering, confirm the following:
Answering these questions before manufacture and delivery reduces project risk. Furthermore, it helps Anderson Corporation identify the correct construction and provide a more accurate quotation.
The RapidConnect C-Series combines several protection systems within one underground cable construction.
Key advantages include:
More importantly, Anderson Corporation helps customers evaluate the complete route rather than treating fibre count as the only selection criterion.
Therefore, this support becomes particularly valuable when the project includes direct burial, industrial environments, electrical infrastructure, unusual drum lengths or difficult hauling conditions.
Choosing the right CST Armoured Fibre Optic Cable involves far more than selecting a fibre count or comparing cable diameters. Instead, successful underground fibre projects require an understanding of steel armour, mechanical loading, rodent exposure, moisture, pathway design and installation practices.
That is why Anderson Corporation is developing one of Australia’s most comprehensive knowledge centres dedicated to CST armoured fibre optic cable and heavy-duty underground fibre infrastructure.
Whether you are designing an industrial backbone, installing a telecommunications network or protecting critical infrastructure, our technical articles will help you make informed engineering decisions.
As our Knowledge Centre grows, you will find practical guidance covering every stage of C-Series selection, specification, installation and lifecycle management.
If you are new to CST armoured fibre optic cable, our educational guides will explain the principles behind steel-armoured underground cable construction.
In particular, you will learn how corrugated steel tape protects a loose tube cable core against rodents, crushing forces and impact. Furthermore, these articles will explain when projects require steel armour and when another cable construction may provide a better solution.
Once you understand the fundamentals, you can explore the engineering that differentiates heavy-duty underground fibre optic cables.
For example, our technical guides will examine corrugated steel tape construction, crush resistance, impact resistance, installation tension and dry water-blocking technology.
Furthermore, these resources will explain how each cable component contributes to long-term underground performance.
Sometimes selecting the right fibre optic cable requires a clear understanding of the available alternatives.
Therefore, our comparison guides will examine how CST armoured fibre optic cable differs from GRP armoured cable, standard loose tube cable, indoor/outdoor cable and other underground fibre constructions.
As a result, engineers, consultants and contractors will be able to compare metallic armour, dielectric protection, installation requirements and mechanical performance more confidently.
Before purchasing any steel-armoured fibre optic cable, project teams should understand the engineering requirements that influence long-term network performance.
Accordingly, our procurement and specification guides will explain how to evaluate fibre count, fibre category, armour construction, cable diameter, pulling tension and optional sheath systems.
In addition, these resources will help consultants and asset owners prepare clearer cable specifications and avoid costly procurement mistakes.

Even the strongest armoured fibre optic cable requires correct installation.
Consequently, our installation guides will focus on practical field techniques that help contractors protect the cable while maintaining its specified bend radius and pulling-tension limits.
Whether the project involves direct burial, underground conduit, pits or industrial infrastructure, these articles will provide practical guidance for route preparation, hauling, jointing and testing.
Underground fibre networks can experience failures that require detailed investigation.
Rather than simply replacing the damaged cable, identifying the underlying cause can help prevent the same problem from affecting the replacement infrastructure.
For this reason, our problem-solving articles will examine rodent attack, crushing forces, impact, moisture, poor backfill, excessive pulling tension and other common causes of underground cable failure.
Installing underground fibre optic cable represents a long-term infrastructure investment.
Therefore, asset owners increasingly evaluate cable systems according to reliability, maintenance requirements and total cost of ownership rather than initial cable price alone.
Our lifecycle and asset-management articles will examine long-term underground survivability, inspection planning, spare fibre capacity, network resilience and future replacement costs.
Ultimately, these resources will help organisations maximise the value of their steel-armoured fibre infrastructure.
Articles Coming Soon
Every industry presents different underground infrastructure challenges.
For example, mining and industrial sites may expose cable to heavy equipment and repeated civil activity. Meanwhile, utility and telecommunications networks may prioritise long-distance reliability, physical security and rapid fault recovery.
Accordingly, our industry application articles will explain how RapidConnect C-Series CST Armoured Fibre Optic Cable supports demanding Australian underground networks.
These resources will cover industrial facilities, mining projects, utility networks, regional infrastructure, telecommunications backbones and critical communications systems.
Articles Coming Soon
CST means Corrugated Steel Tape. Specifically, the steel tape forms an armour layer around the cable core. Consequently, it improves resistance to rodents, crushing forces and impact.
The industry commonly uses “rodent proof” to describe steel-armoured cable. However, the more precise description is a cable that provides a high level of rodent resistance.
Yes. The C-Series suits direct-burial applications. Nevertheless, contractors must still provide correct trench preparation, bedding, backfill, burial depth and route marking.
Yes. In fact, CST cable can provide additional mechanical protection inside underground conduits. However, designers must confirm conduit capacity, bend radius and pulling tension.
No. Instead, the C-Series focuses on underground infrastructure. Therefore, use an appropriately engineered ADSS cable for self-supporting aerial routes.
No. Specifically, the optical fibres carry data as light. However, the metallic armour introduces electrical bonding and earthing considerations.
The standard range supports up to 96 fibres. In particular, constructions from 2 to 72 fibres use six elements, while the 96-fibre cable uses eight.
Customers can select OS2 Singlemode, OM3 Multimode or OM4 Multimode fibre. However, they should confirm availability and coding when requesting a quotation.
The C-Series supports a maximum installation tension of 2.5 kN. Nevertheless, installers should keep the actual load below this limit wherever possible.
The cable provides a nominal short-term rating of 6.0 kN/100 mm. Meanwhile, its nominal long-term rating reaches 3.0 kN/100 mm.
The cable requires 30 times its outside diameter under load. By contrast, it requires 15 times its outside diameter without load.
The water-blocking material swells after contact with water. As a result, it helps restrict moisture migration along the cable core.
No. Instead, water blocking provides a secondary defence. Therefore, installers must still seal cable ends, joints, pits and building entries.
The blue nylon jacket supports termite resistance and reduces hauling friction. However, installers must protect it against cuts and abrasion.
The optional black PE sheath protects the underlying nylon jacket during hauling and installation. Consequently, it may suit abrasive or uncertain pathways.
It adds approximately 2 mm to the cable diameter and increases the cable weight. Therefore, designers must check conduit capacity and hauling requirements.
CST uses conductive steel tape for heavy mechanical protection. By contrast, GRP uses non-metallic armour and supports an all-dielectric construction.
Possibly. However, the project engineer must assess the metallic armour, earthing, separation and electrical environment.
The C-Series primarily serves underground and external infrastructure. Therefore, designers must assess applicable fire and building-entry requirements before bringing it indoors.
Eligible C-Series installations can form part of the RapidConnect 25-Year Enterprise Cabling Infrastructure System Warranty. However, product, installation, testing and registration conditions apply.
First, provide Anderson Corporation with the fibre type, fibre count, cable length, installation environment, sheath requirement, delivery location and project timing. Furthermore, complex projects should include route details and required drum lengths.
Underground fibre infrastructure should reflect the consequences of failure rather than only the initial cable price.
The RapidConnect C-Series CST Armoured Fibre Optic Cable combines corrugated steel tape armour, dry water blocking and heavy-duty outdoor construction. Consequently, it protects critical optical fibres against rodents, crushing forces, impact and demanding underground conditions.
Therefore, the C-Series provides a strong solution for direct-burial networks, industrial facilities, telecommunications backbones, utility infrastructure, mining projects and other high-risk underground routes.
Contact Anderson Corporation to discuss your CST Armoured Fibre Optic Cable requirements, confirm the correct construction and request project pricing.
