Mini Loose Tube Fibre Optic Cable Diameter: Why Smaller Means More Capacity

Mini Loose Tube Fibre Optic Cable diameter can significantly influence how much useful network capacity engineers can obtain from existing duct and conduit infrastructure. In underground fibre networks, every millimetre of cable diameter occupies valuable pathway space. Therefore, compact cable construction can provide benefits that extend well beyond easier cable handling.

Importantly, this issue becomes more significant when conduits already contain services, civil expansion is difficult or network owners expect substantial future growth. In these situations, simply selecting a cable with enough fibres for today’s requirement can overlook a much larger infrastructure question:

How efficiently does that cable use the available conduit?

The RapidConnect® TR-Series Mini Loose Tube Fibre Optic Cable uses compact Mini Loose Tube construction to provide high fibre density within a reduced cable footprint. As a result, engineers can pursue higher fibre capacity while using finite underground pathways more efficiently.

However, smaller diameter should never mean reducing the cable’s engineering requirements. Instead, good cable design must balance compact construction with mechanical protection, environmental durability, installation performance and long-term reliability.

Why Cable Diameter Matters in Fibre Networks

It is easy to treat cable diameter as just another number on a technical datasheet.

However, in a duct or conduit installation, diameter directly affects the amount of pathway space that the cable consumes. Consequently, outside diameter can influence both current installation decisions and future network expansion.

That matters because underground infrastructure has finite physical capacity.

Once a conduit becomes congested, expanding the network may require:

• Installing another conduit.
• Constructing a new underground route.
• Excavating established infrastructure.
• Installing additional pits.
• Obtaining permits or approvals.
• Implementing traffic management.
• Disrupting operational sites.
• Reconfiguring existing services.

Therefore, the real cost of a larger cable may not appear when the cable is purchased.

Instead, the cost can emerge years later when the network needs additional capacity but the existing pathway has insufficient room.

For this reason, engineers should consider cable diameter as an infrastructure-capacity variable, not simply a product dimension.

The Problem: Fibre Demand Grows but Conduits Do Not

Network capacity requirements rarely remain static.

Over time, organisations continually add:

• Network connections.
• CCTV cameras.
• Buildings.
• Telecommunications equipment.
• Industrial systems.
• Security infrastructure.
• Utility monitoring.
• Transport systems.
• Operational technology.

However, the underground conduit installed during the original project usually remains the same size.

This creates a fundamental infrastructure problem:

Network demand can grow. Conduit diameter cannot.

Therefore, network designers need to obtain as much useful capacity as practical from the pathways already available.

One solution involves installing additional conduits during initial construction. However, that opportunity does not always exist, particularly when engineers upgrade established networks.

Alternatively, designers can use the available conduit more efficiently.

This is where compact Mini Loose Tube cable construction becomes particularly valuable.

Smaller Cable Diameter Can Increase Pathway Capacity

A smaller cable occupies less cross-sectional area inside a conduit.

Importantly, that relationship is more significant than it may initially appear because the cross-sectional area of a circular cable changes with the square of its radius.

The basic relationship is:

Area = π × radius²

Therefore, a relatively modest reduction in cable outside diameter can produce a considerably larger reduction in the physical cross-sectional area occupied by the cable.

For example, consider two hypothetical circular cables:

• Cable A has a 12 mm outside diameter.
• Cable B has a 9 mm outside diameter.

Cable A has a cross-sectional area of approximately 113 mm².

By comparison, Cable B has a cross-sectional area of approximately 64 mm².

Although the diameter has fallen by only 25%, the cross-sectional area has fallen by approximately 44%.

That distinction is important.

However, this does not mean engineers should simply pack as many cables as possible into a conduit. Conduit fill, installation method, pulling performance, route geometry and applicable requirements still matter.

Instead, the key principle is straightforward:

A compact cable gives the designer more options within the same physical pathway.

Ultimately, that flexibility can become extremely valuable over the life of the network.

Conduit Capacity Is About Area, Not Just Diameter

When assessing whether a cable will fit within a conduit, engineers should not simply compare cable diameter with conduit diameter.

Instead, the relationship between the cross-sectional areas of the cables and the usable internal area of the pathway becomes important.

This is why visual assessments can be misleading.

A conduit may appear to have considerable spare room when viewed from an access point. However, existing cable occupancy, bends, internal diameter, pulling conditions and route length can substantially affect whether another cable can actually be installed.

Therefore, project-specific design should consider:

• Conduit internal diameter.
• Cable outside diameter.
• Existing cable occupancy.
• Number of cables.
• Route length.
• Number and severity of bends.
• Cable pulling requirements.
• Applicable installation standards.

Moreover, Australian telecommunications infrastructure operates within established cabling requirements. The Australian Communications and Media Authority identifies AS/CA S009:2020 Installation requirements for customer cabling as the Wiring Rules covering installation and maintenance practices for applicable telecommunications cabling. (ACMA)

For current Australian regulatory and standards information, see the ACMA Australian cabling standards guidance.

Accordingly, compact cable design should support good pathway engineering rather than replace it.

More Fibres per Millimetre Changes the Capacity Equation

Cable capacity should not be assessed only by asking:

How many fibres does this cable contain?

Instead, a better question is:

How many fibres can this cable provide for the physical space it occupies?

Essentially, this is a fibre-density question.

Traditional cable architectures may require a larger overall structure to accommodate a particular fibre count. By contrast, compact Mini Loose Tube construction aims to package fibres more efficiently.

Therefore, cable diameter becomes particularly important as fibre counts increase.

For example, a high fibre count provides substantial optical capacity. However, if achieving that capacity requires an unnecessarily large cable, the design may consume more pathway space than necessary.

Compact construction attempts to solve both sides of the problem:

more optical capacity and more efficient physical utilisation.

As a result, engineers can evaluate cable capacity in relation to the infrastructure required to support it.

Why Existing Conduits Make Mini Loose Tube Fibre Optic Cable Diameter Even More Important

Cable diameter becomes especially important when engineers work with established infrastructure.

A new greenfield project may allow designers to specify additional conduits from the beginning.

However, an existing network may offer no such flexibility.

Instead, engineers may need to work with:

• Existing underground ducts.
• Fixed conduit diameters.
• Established pit systems.
• Existing cables.
• Limited spare pathways.
• Road crossings.
• Building penetrations.
• Congested infrastructure corridors.

In these situations, every new cable consumes part of a resource that may be difficult or expensive to replace.

Therefore, compact cable construction can help preserve the usefulness of existing civil infrastructure.

Our Mini Loose Tube Fibre Optic Cable Fibre Count Guide examines this relationship from the capacity-planning perspective. In particular, it explains why engineers should consider fibre count, available conduit space and the difficulty of installing another cable as interconnected decisions.

Consequently, cable diameter and fibre count should rarely be specified independently.

Smaller Mini Loose Tube Fibre Optic Cable Diameter Can Help Preserve Space for Future Cables

A fibre network may satisfy its capacity requirement on commissioning day yet still require substantial expansion later.

For example, a campus backbone might initially require one cable. Several years later, another building, CCTV network or operational system may require a second connection through the same underground infrastructure.

If the original cable consumed unnecessary conduit space, the second installation may become more difficult.

By contrast, selecting a compact cable can help preserve pathway capacity.

However, that does not guarantee that another cable can always be installed later. Route bends, existing cables, pulling tension, duct condition and applicable requirements can all affect feasibility.

Nevertheless, efficient use of the available cross-sectional area provides engineers with more options.

Therefore, cable diameter should form part of future-capacity planning from the first installation.

Smaller Cable Can Reduce Pressure for Additional Civil Works

Civil construction often represents a substantial component of an underground fibre project.

Depending on the route, installing a new pathway can involve:

• Trenching.
• Directional boring.
• Road crossings.
• Concrete cutting.
• New pits.
• Reinstatement.
• Permits.
• Traffic control.
• Labour.
• Site disruption.

Consequently, making better use of an existing conduit can have considerable commercial value.

Furthermore, civil works can become especially challenging where the route crosses established roads, landscaped areas, operational industrial facilities or other infrastructure.

Therefore, cable diameter can influence far more than the cable installation itself.

A compact cable may help defer the point at which another pathway becomes necessary. In some cases, it may also allow engineers to accommodate future capacity within infrastructure that already exists.

For network owners, that can turn a seemingly small dimensional specification into a significant whole-of-life infrastructure consideration.

High Fibre Count and Small Mini Loose Tube Fibre Optic Cable Diameter Work Together

There are two principal ways to increase the useful capacity of a fibre route.

First, engineers can install more cables.

Alternatively, they can increase the number of fibres available within the cable infrastructure.

Where conduit space is limited, the second approach can become particularly attractive.

For example, installing a higher fibre count during the original project may provide spare capacity for future services without requiring another cable installation.

However, increasing fibre count should not automatically result in an unnecessarily large cable.

Instead, compact cable engineering aims to improve the relationship between:

• Fibre count.
• Cable diameter.
• Conduit utilisation.
• Future capacity.

The RapidConnect® TR-Series Mini Loose Tube Fibre Optic Cable applies this principle through compact Mini Loose Tube construction for outdoor duct and conduit networks.

As a result, engineers can evaluate capacity not merely in fibres per cable but in fibres relative to the pathway space consumed.

Compact Cable Design Can Improve Installation Practicality

Cable diameter also affects practical installation considerations.

For example, a compact cable can provide advantages where routes include:

• Restricted conduit space.
• Multiple bends.
• Existing services.
• Underground pits.
• Building entries.
• Confined access points.

However, smaller diameter does not remove the need for correct installation practices.

Installers must still observe:

• Maximum pulling tension.
• Minimum bend radius.
• Conduit requirements.
• Approved pulling methods.
• Appropriate cable handling.
• Route-specific installation procedures.

Furthermore, a smaller cable should never encourage installers to exceed the engineering limits of the complete cable assembly.

For detailed field guidance, our Mini Loose Tube Fibre Optic Cable Installation article explains conduit preparation, pulling, bend-radius control and commissioning in greater detail.

Therefore, compact construction should make an appropriate installation more efficient rather than justify poor installation practice.

Mini Loose Tube Fibre Optic Cable Diameter and Bend Radius Are Connected

Cable diameter can also influence the physical geometry required during installation and cable management.

However, engineers should distinguish this mechanical relationship from the optical bend performance of the fibres inside the cable.

A compact cable can provide practical benefits within:

• Underground pits.
• Cable chambers.
• Equipment areas.
• Building entries.
• Restricted pathway transitions.

Nevertheless, engineers must always use the manufacturer’s specified minimum bend radius for the particular cable configuration.

Therefore, smaller diameter should never be interpreted as permission to bend the cable without regard to its specification.

Smaller does not mean bend it however you like.

Instead, compact construction can support more efficient cable management while correct bend control continues to protect the cable.

G.657.A2 Complements Compact Cable Architecture

Optical fibre technology also contributes to modern high-density network design.

The RapidConnect® TR-Series uses G.657.A2 bend-insensitive singlemode optical fibre in its singlemode configuration.

G.657.A2 provides enhanced resistance to macrobending loss. Therefore, it complements compact cable architectures and confined fibre-management environments.

However, G.657.A2 does not make the finished cable smaller by itself.

The complete cable architecture determines outside diameter.

Instead, G.657.A2 contributes to the broader engineering objective of supporting compact fibre systems while providing enhanced optical bend performance.

Our G.657.A2 Mini Loose Tube Fibre guide explains this distinction in greater detail, including why fibre bend performance must not be confused with the mechanical bend radius of the finished cable.

Consequently, compact cable design and bend-insensitive fibre should be viewed as complementary technologies rather than interchangeable specifications.

Smaller Should Never Mean Less Protection

Reducing cable diameter only creates value if the finished cable still provides the protection required by the application.

This distinction is critical.

An outdoor fibre cable may encounter:

• Water.
• Humidity.
• Temperature variation.
• Pulling forces.
• Mechanical stress.
• Underground environmental conditions.
• Long service periods.

Therefore, compact construction must still incorporate appropriate environmental and mechanical protection.

The RapidConnect® TR-Series combines its Mini Loose Tube architecture with:

• G.657.A2 bend-insensitive fibre in singlemode configurations.
• Water Blocking Technology.
• Triple Protection Technology.
• A premium PA12 Blue Nylon jacket.

Consequently, the design objective is not simply to manufacture a thin cable.

Instead, the objective is to achieve efficient fibre density within a cable engineered for demanding outdoor duct and conduit environments.

This distinction should remain central to any diameter comparison.

Water Protection Still Matters in a Compact Cable

Reducing the cable footprint does not remove the environmental challenges associated with underground infrastructure.

For example, water can enter pits and conduits through groundwater, drainage problems, damaged infrastructure or severe weather.

Therefore, compact cable construction still needs an appropriate strategy for moisture protection.

The TR-Series incorporates Water Blocking Technology to help restrict longitudinal water migration within the cable.

Our Water Blocking Technology in Mini Loose Tube Fibre Optic Cable article explains this aspect of cable construction in greater detail.

Importantly, this demonstrates why cable diameter should never be considered alone.

A useful compact cable needs to achieve reduced physical size while retaining the environmental protection required by its intended application.

Why PA12 Matters in a Compact Outdoor Cable

The outer jacket also remains an important part of the complete cable system.

The RapidConnect® TR-Series uses a premium PA12 Blue Nylon jacket.

In a compact cable, material selection matters because the design still needs to protect the internal cable structure throughout installation and long-term operation.

Therefore, engineers should evaluate cable diameter alongside jacket construction rather than considering the two characteristics independently.

Our PA12 Nylon Fibre Optic Cable article examines the role PA12 plays in demanding outdoor fibre cable applications.

Again, the engineering objective is balance:

compact size without treating protection as optional.

Mini Loose Tube Fibre Optic Cable Diameter Can Affect Procurement Decisions

Procurement teams often compare fibre cables using familiar specifications such as:

• Fibre count.
• Fibre type.
• Jacket material.
• Tensile rating.
• Temperature rating.
• Price.

However, overall cable diameter deserves attention as well.

Two cables that provide the same fibre count may not consume the same amount of pathway space.

Therefore, when comparing cable options, procurement teams should ask:

What is the outside diameter?

How much pathway capacity will it consume?

Does the design provide an efficient fibre count for its physical footprint?

Will the remaining pathway support future expansion?

Could choosing a larger cable contribute to future civil costs?

These questions shift procurement from simple product comparison towards infrastructure optimisation.

Moreover, they encourage buyers to consider the total installed network rather than only the price per metre of cable.

Do Not Specify Fibre Count Without Checking Mini Loose Tube Fibre Optic Cable Diameter

Fibre count and cable diameter should be evaluated together.

For example, a project may specify 96 fibres because the network requires substantial future capacity.

That decision may be entirely appropriate.

However, engineers should still confirm the physical characteristics of the proposed 96-fibre cable.

Relevant specifications include:

• Outside diameter.
• Cable mass.
• Minimum bend radius.
• Maximum pulling tension.
• Conduit compatibility.
• Pathway requirements.
• Pit requirements.

Our Mini Loose Tube Fibre Optic Cable Fibre Count Guide examines how engineers can balance present capacity, future growth, redundancy and available pathway space.

Therefore, the correct objective is not simply more fibres.

Instead, it is the right fibre capacity in an efficient and installable cable architecture.

Do Not Compare Mini Loose Tube Fibre Optic Cable Diameter Without Comparing Construction

The opposite mistake can also occur.

For instance, a procurement team may identify the smallest-diameter cable on a comparison table and automatically assume that it provides the best solution.

However, that approach is too simplistic.

Cable diameter should always be considered alongside:

• Fibre count.
• Cable construction.
• Environmental protection.
• Tensile performance.
• Crush performance.
• Water-blocking design.
• Jacket material.
• Temperature requirements.
• Installation method.
• Application suitability.

A small cable that does not meet the mechanical or environmental requirements of the project provides little value.

Therefore, diameter should function as one component of a complete engineering assessment.

Ultimately, the goal is not minimum diameter at any cost. Instead, the goal is maximum useful infrastructure efficiency while satisfying the technical requirements of the network.

Think in Terms of Pathway Efficiency

A useful way to approach cable selection is to think in terms of pathway efficiency.

Instead of evaluating only the cable, consider the complete relationship between:

fibre capacity + cable diameter + conduit capacity + future network growth.

This changes the specification process.

For example, suppose two cable designs can provide the required fibre count.

If one achieves that capacity within a more compact, appropriately engineered construction, it may preserve more pathway space for future requirements.

That preserved space has infrastructure value.

Likewise, if a compact higher-fibre-count cable allows the network owner to accommodate future growth without installing another cable, its value may extend far beyond the initial product cost.

Therefore, cable diameter should form part of network-capacity planning rather than remain buried in a datasheet.

Smaller Cable Does Not Mean Unlimited Conduit Capacity

Compact cable design improves pathway efficiency, but it does not create unlimited space.

Engineers must still account for:

• Conduit internal diameter.
• Existing cable occupancy.
• Route bends.
• Cable friction.
• Pulling distance.
• Installation method.
• Cable pulling tension.
• Applicable installation requirements.

Furthermore, installing another cable into a conduit containing existing services may introduce additional installation challenges.

Therefore, available physical space alone does not determine whether another cable can be installed successfully.

Instead, compact cable provides additional design flexibility, not permission to ignore installation engineering.

For this reason, engineers should consider both the mathematical space available and the practical installation conditions along the entire route.

Mini Loose Tube Fibre Optic Cable Diameter Matters in Underground Pits Too

The conduit is not the only location where cable diameter can influence network design.

Underground pits may also contain:

• Existing fibre cables.
• Slack loops.
• Conduit entries.
• Splice infrastructure.
• Future cable routes.
• Other telecommunications services.

Consequently, cable geometry can affect how efficiently technicians can organise and maintain infrastructure within the available pit space.

However, pit design involves much more than cable diameter alone.

Bend radius, slack management, access, drainage and future maintenance also require consideration.

Therefore, our Installing Mini Loose Tube Fibre Cable in Underground Pits article covers those pit-specific installation issues separately.

This distinction also prevents cable diameter guidance from becoming another general installation article.

Smaller Mini Loose Tube Fibre Optic Cable Diameter Can Support Industrial Network Expansion

Industrial sites provide another strong example of why pathway efficiency matters.

Factories, processing facilities, utilities and other industrial sites can accumulate communications infrastructure over many years.

Meanwhile, installing additional underground pathways may interfere with:

• Production.
• Roads.
• Heavy-vehicle routes.
• Existing services.
• Machinery.
• Security infrastructure.
• Site operations.

Therefore, preserving conduit capacity can become strategically important.

A compact cable cannot eliminate every future civil requirement. However, it can help engineers make better use of the infrastructure already available.

As a result, cable diameter can influence the long-term flexibility of an industrial network.

Maintenance Benefits From Efficient Infrastructure

Compact cable construction can also contribute to more manageable infrastructure.

For example, heavily congested pits and pathways can make future work more difficult.

Technicians may need to identify existing cables, inspect infrastructure or install additional services without disturbing operational fibre.

Therefore, preserving physical space can improve more than expansion capacity.

It can also support:

• Easier cable identification.
• Better pathway organisation.
• Improved access.
• Reduced congestion.
• More practical future modifications.

Our Mini Loose Tube Fibre Cable Maintenance and Inspection Guide explains why accessibility, records and infrastructure condition matter throughout the life of the fibre network.

Consequently, efficient cable geometry can contribute to both capacity planning and long-term asset management.

When Is Smaller Mini Loose Tube Fibre Optic Cable Diameter Most Valuable?

Compact Mini Loose Tube cable construction becomes particularly valuable when:

• Existing conduit space is limited.
• Fibre counts are increasing.
• Installing additional ducts would be expensive.
• Routes pass beneath established infrastructure.
• Civil construction would cause disruption.
• Long-term network growth is expected.
• Underground pits provide restricted space.
• Multiple network services share the same corridor.
• Future pathway capacity has strategic value.
• High fibre density is required.

These conditions frequently occur across telecommunications, utility, industrial, transport, government, campus and regional networks.

Therefore, cable diameter can become an important specification criterion for both new projects and network upgrades.

However, the greatest benefit usually occurs where civil infrastructure is difficult or expensive to expand.

A Better Way to Specify Fibre Capacity

Rather than asking only:

How many fibres do we need?

engineers should ask a sequence of questions.

First:

How many fibres do we need now?

Next:

How many fibres are we likely to need during the life of the infrastructure?

Then:

What cable diameter provides that capacity?

Finally:

How efficiently does that cable use the available conduit while still meeting the project’s mechanical and environmental requirements?

This approach links optical capacity directly to physical infrastructure.

As a result, engineers can make more informed decisions about both the cable and the pathway that supports it.

Furthermore, the process encourages project teams to consider future network requirements before the available conduit becomes constrained.

Look Beyond Price per Metre

Cable procurement frequently focuses on initial product cost.

However, price per metre represents only one component of the total infrastructure cost.

A more complete assessment may consider:

• Cable cost.
• Installation cost.
• Available conduit capacity.
• Future fibre requirements.
• Potential additional cable installations.
• Future civil works.
• Operational disruption.
• Maintenance accessibility.

Therefore, a cable that uses existing infrastructure more efficiently may deliver value that is not obvious from its purchase price alone.

For example, preserving enough conduit capacity for a future expansion could prove substantially more valuable than a small difference in initial cable cost.

Consequently, network owners should evaluate cable diameter through a whole-of-life infrastructure lens.

Why the RapidConnect® TR-Series Uses Compact Construction

The purpose of Mini Loose Tube construction is not simply to make the cable look smaller on a datasheet.

Instead, compact construction addresses a genuine network infrastructure problem: how to provide useful fibre capacity without unnecessarily consuming finite duct and conduit space.

The RapidConnect® TR-Series Mini Loose Tube Fibre Optic Cable combines this compact architecture with technologies designed for outdoor duct and conduit applications.

These include:

Mini Loose Tube construction for efficient fibre packaging.

G.657.A2 bend-insensitive optical fibre in singlemode configurations for enhanced resistance to macrobending loss.

Water Blocking Technology to help restrict longitudinal water migration.

Triple Protection Technology for additional cable protection.

Premium PA12 Blue Nylon jacketing as the external protective layer.

Therefore, the objective is not simply smaller diameter.

Instead, the objective is to combine compact geometry, useful fibre density and appropriate outdoor cable protection within one cable system.

Frequently Asked Questions – Mini Loose Tube Fibre Optic Cable Diameter

Why does Mini Loose Tube Fibre Optic Cable diameter matter?

Cable diameter affects how much physical space the cable occupies within a duct or conduit. Therefore, a compact cable can help engineers use existing pathway capacity more efficiently.

Does a smaller cable mean I can install more cables in a conduit?

Potentially, but not automatically. Engineers must still assess conduit dimensions, existing cables, pulling conditions, route geometry and applicable installation requirements.

Why does a small change in Mini Loose Tube Fibre Optic Cable Diameter make such a difference?

Because cable cross-sectional area depends on the square of the radius. Consequently, reducing diameter can produce a proportionally larger reduction in the physical area occupied by the cable.

Can a smaller fibre cable contain a high fibre count?

Yes. Compact cable architectures can package substantial fibre capacity into relatively small physical dimensions. However, engineers should compare the complete cable specifications rather than fibre count or diameter alone.

Does G.657.A2 make Mini Loose Tube Fibre Optic Cable Diameter smaller?

Not by itself. The complete cable architecture determines outside diameter. However, G.657.A2 bend-insensitive fibre complements compact fibre cable and management designs.

Is the smallest cable always the best cable?

No. Engineers must also consider mechanical performance, water protection, jacket construction, tensile requirements, temperature rating and application suitability. Therefore, diameter should never be assessed in isolation.

Why can smaller cable diameter reduce future network costs?

A compact cable can preserve more usable pathway capacity. Consequently, future expansion may be possible without immediately constructing additional underground infrastructure.

Should Mini Loose Tube Fibre Optic Cable Diameter be included in fibre procurement decisions?

Yes. Procurement teams should evaluate outside diameter alongside fibre count, mechanical specifications, environmental protection and conduit compatibility.

Conclusion – Mini Loose Tube Fibre Optic Cable Diameter

Mini Loose Tube Fibre Optic Cable diameter matters because underground network capacity depends on more than the number of fibres inside a cable.

It also depends on how efficiently that cable uses the physical infrastructure surrounding it.

Therefore, a smaller, appropriately engineered cable can occupy less conduit space, support higher pathway efficiency and preserve greater flexibility for future network growth. Consequently, compact construction can help network owners extract more value from existing ducts while potentially reducing pressure for disruptive future civil works.

However, smaller should never mean compromising cable protection or installation performance. Engineers must still evaluate fibre count, tensile requirements, bend radius, environmental protection, jacket construction and conduit compatibility as part of the complete specification.

The RapidConnect® TR-Series Mini Loose Tube Fibre Optic Cable combines compact Mini Loose Tube construction with G.657.A2 bend-insensitive singlemode fibre, Water Blocking Technology, Triple Protection Technology and a premium PA12 Blue Nylon jacket for outdoor duct and conduit networks.

Ultimately, the objective is not simply to install the smallest cable.

Instead, it is to achieve more useful fibre capacity from finite pathway infrastructure without sacrificing the engineering performance the network requires.
