RapidConnect CS Patch Leads deliver compact, high-density two-fibre connectivity for modern optical networks. Available in CS-to-CS and LC-to-CS configurations, these factory-terminated leads support OS2 singlemode and OM4 multimode applications.
CS Patch Leads provide compact, two-fibre connectivity for high-density optical networks. Each lead uses the SENKO CS® Very Small Form Factor connector to reduce the space required at patching and equipment interfaces. Consequently, network designers can increase connection density while retaining familiar duplex transmit-and-receive fibre architecture.
Anderson Corporation supplies CS-to-CS and LC-to-CS patch leads for data centres, telecommunications networks, enterprise infrastructure and other high-performance optical systems. Available configurations include OS2 singlemode and OM4 multimode fibre. Moreover, customers can specify the required connector combination, end-face geometry, cable length and other assembly details.
Unlike a traditional duplex LC interface, one CS connector houses two 1.25 mm ceramic ferrules within a compact connector body. Therefore, each connector supports a complete two-fibre optical channel. An integrated push-pull mechanism also helps technicians install and remove connectors where finger access is limited.
CS technology offers an important bridge between established duplex fibre cabling and new high-density equipment. For example, an LC-to-CS patch lead can connect an existing LC duplex patching environment to equipment fitted with a CS interface. Meanwhile, a CS-to-CS patch lead can support an end-to-end CS connection where both interfaces use the CS format.
However, connector density alone does not determine network performance. Fibre type, end-face geometry, polarity, insertion loss, cleanliness and compatibility all affect the completed optical channel. For that reason, every CS patch lead should match the equipment interface and the wider cabling system.
A CS patch lead is a factory-terminated fibre optic cable with a CS connector on at least one end. The opposite end may also use a CS connector, or it may use another duplex connector such as LC. Anderson Corporation primarily offers CS-to-CS and LC-to-CS configurations.
Each CS connector carries two optical fibres. Typically, one fibre supports transmission in one direction, while the second fibre supports transmission in the opposite direction. Therefore, the connector provides Base-2 duplex connectivity within one compact housing.
The CS connector uses two 1.25 mm ceramic ferrules. LC connectors also use 1.25 mm ferrules. However, a duplex LC assembly usually combines two separate LC connector bodies with a clip. In contrast, CS places both ferrules into one purpose-designed, compact connector body.
This construction provides several practical benefits:
Nevertheless, CS and LC are physically different connector formats. Therefore, a CS connector cannot plug directly into an LC adaptor or LC transceiver port. The equipment, adaptor or cassette must provide the correct CS interface.
If a network uses conventional SC, LC, ST or FC connectivity, Anderson Corporation’s broader Fibre Optic Patch Leads Authority Hub explains the standard connector and fibre options available.
Network equipment continues to carry more data within less physical space. Consequently, equipment manufacturers and network operators need smaller optical interfaces that can support greater connection density.
Traditional duplex LC connectivity remains widely used. However, two LC connector bodies and their duplex clip occupy valuable front-panel space. This footprint can limit port density in transceivers, patch panels, cassettes and network equipment.
The CS connector addresses this limitation by combining two ferrules within one compact housing. As a result, the connector maintains a two-fibre channel while reducing the physical space required at the interface.
The connector also supports higher-density equipment designs. For example, selected QSFP-DD, OSFP and SFP-DD transceiver arrangements can use multiple CS connections to separate parallel optical lanes into individual two-fibre channels. However, the exact interface depends on the transceiver model and equipment design.
Therefore, network designers should never assume that every high-speed transceiver accepts a CS connector. Instead, they must verify the manufacturer’s interface specification before ordering patch leads.
Importantly, this density comparison concerns the connector interface. It does not mean that replacing an LC patch lead with a CS lead automatically quadruples the capacity of an existing network. The patch panel, adaptor, transceiver and equipment layout must all support the denser CS format.
SENKO classifies CS as a Very Small Form Factor, or VSFF, connector. VSFF connectors reduce interface size while supporting the optical performance required by modern fibre networks.
The CS connector achieves this compact format without replacing conventional single-fibre ferrule technology with a multi-fibre rectangular ferrule. Instead, it retains two separate 1.25 mm ceramic ferrules. Therefore, the connector remains a Base-2 solution built around two-fibre duplex channels.
This distinction matters because Base-2 connectivity aligns naturally with many conventional Ethernet optical links. One fibre carries the transmitted signal, while the other carries the received signal. Consequently, technicians can work with familiar transmit-and-receive polarity principles.
The compact design can provide several advantages:
CS adaptors can place more two-fibre connections within a given panel area than conventional duplex LC adaptors. Therefore, a network may accommodate more ports without adding equivalent rack space.
Equipment manufacturers can use compact optical interfaces to increase port density. Consequently, switches, transceivers and other devices may support more connections across a limited front-panel area.
Compact connectors can help manufacturers design smaller or higher-capacity modular cassettes. However, cassette capacity still depends on fibre routing, bend-radius control, adaptor placement and internal management.
Greater density can make connector access difficult. Therefore, the CS connector includes a push-pull mechanism that helps technicians insert or remove it without gripping the connector body directly.
Each connector terminates two individual fibres. As a result, CS can support duplex applications without introducing an MPO/MTP multi-fibre interface into the patching connection.
A CS connector combines several components into a compact assembly. Each component contributes to alignment, protection, strain relief or handling.
The connector contains two 1.25 mm zirconia ceramic ferrules. These ferrules hold and align the two optical fibres. Precise alignment helps minimise optical loss when two connectors mate through an adaptor or equipment receptacle.
The housing positions both ferrules within a single connector body. Consequently, CS provides two-fibre connectivity without the separate bodies used by a duplex LC assembly.
A push-pull tab allows technicians to operate the connector in confined spaces. Instead of reaching around the connector body, the technician can use the tab to engage or disengage the connector.
The boot supports the cable where it enters the connector. Therefore, it reduces excessive stress at the termination point. Nevertheless, technicians must still avoid pulling, sharply bending or twisting the patch lead.
Dust caps protect the ferrule end faces during storage and transport. However, a dust cap does not guarantee that an end face remains clean. Caps can contain or transfer contamination. Therefore, technicians should inspect the connector before every mating.
A standard CS connector is inherently a two-fibre connector. Consequently, Anderson Corporation positions these CS patch leads as duplex assemblies rather than offering the connector as a conventional single-fibre simplex product.
This point avoids a common source of confusion. The cable may appear as one round outer jacket, yet it still contains two optical fibres. Therefore, the number of outer cable jackets does not determine whether the optical connection is simplex or duplex.
A compact round cable can protect both fibres within one shared jacket. As a result, the assembly can reduce cable bulk and support the unified CS connector body. The construction also creates a tidy patching arrangement within high-density cabinets.
The two fibres must maintain the correct transmit-and-receive relationship throughout the link. Therefore, polarity remains essential even though both fibres share one connector and one cable jacket.
A CS-to-CS patch lead has a CS connector at both ends. This configuration supports connections where both optical interfaces accept CS connectors.
Potential applications include:
CS-to-CS assemblies retain the connector’s compact format across both ends of the connection. Therefore, they provide the greatest density benefit where the complete patching environment uses CS connectivity.
However, network designers must confirm the required polarity before ordering. They must also verify whether the equipment requires UPC or APC end faces. A physically compatible connector with the wrong polish cannot provide a suitable connection.
An LC-to-CS patch lead has a duplex LC connector arrangement at one end and a CS connector at the other. Therefore, it connects established LC duplex infrastructure to newer equipment or panels fitted with CS interfaces.
This hybrid configuration can support:
LC-to-CS patch leads can protect the value of an existing LC cabling system. For example, an organisation may retain its installed LC patch panels while deploying switches or transceivers with CS ports. Consequently, only the equipment patching changes.
However, a hybrid lead does not convert optical standards. It simply provides different connector formats at each end of the same two fibres. Therefore, the transceiver wavelength, fibre type, link budget and transmission standard must still match.
An LC-to-CS lead also requires defined polarity. The transmit and receive positions at the duplex LC end must map correctly to the corresponding CS ferrules. As a result, ordering information should clearly state the required orientation.
CS and duplex LC patch leads can both support two-fibre optical channels. Nevertheless, they use different physical interfaces and suit different network designs.
| Feature | CS Patch Lead | Duplex LC Patch Lead |
|---|---|---|
| Fibre count | Two fibres | Two fibres |
| Ferrule diameter | 1.25 mm | 1.25 mm |
| Connector arrangement | Two ferrules in one compact body | Two LC bodies joined as a duplex pair |
| Interface category | Very Small Form Factor | Small Form Factor |
| Density | Higher in compatible equipment | Conventional density |
| Operation | Integrated push-pull mechanism | LC latch, sometimes with a pull tab |
| Installed base | Emerging high-density systems | Very widely installed |
| Equipment compatibility | Requires CS interface | Requires duplex LC interface |
| Hybrid option | LC-to-CS available | LC-to-CS available |
| Typical purpose | High-density and next-generation interfaces | General enterprise, carrier and data centre connectivity |
The best connector depends on the interfaces within the network. If both devices provide LC ports, a duplex LC patch lead remains the correct choice. Conversely, if one device provides a CS port, the assembly must include a CS connector at that end.
Therefore, CS should not be viewed as a universal replacement for LC. Instead, it provides a compact alternative for equipment and patching systems specifically designed around the CS interface.
CS may offer a strong advantage where rack space, panel space or transceiver density creates a constraint. However, LC may remain preferable where compatibility with an extensive installed base matters more than maximum density.
OS2 singlemode fibre supports long-distance and high-bandwidth optical transmission across a wide range of network applications. Anderson Corporation’s current fibre standard uses G.657.A2 bend-insensitive singlemode fibre for relevant patch lead constructions.
G.657.A2 fibre provides improved resistance to bend-induced attenuation compared with traditional singlemode fibre designs. Consequently, it suits compact patching environments where cable routing can become tight.
However, bend-insensitive fibre does not remove minimum bend-radius requirements. Excessive bending can still increase attenuation, damage the cable or shorten its service life. Therefore, installers must route CS patch leads through suitable guides and maintain controlled bends.
OS2 CS patch leads may suit:
The cable jacket will generally use yellow to identify singlemode fibre. Nevertheless, jacket colour alone cannot confirm fibre type. Therefore, technicians should verify the product label and ordering code before installation.
OM4 multimode fibre supports high-speed short-reach connections in data centres and enterprise networks. Consequently, OM4 CS patch leads can combine high-density connector technology with a recognised laser-optimised multimode platform.
OM4 applications may include:
Anderson Corporation identifies OM4 patch cabling with Erika Violet, specifically RAL 4003. This colour provides a clear visual distinction from yellow OS2 singlemode assemblies.
However, colour does not establish optical compatibility. Some network environments use aqua or other colours for multimode products. Therefore, technicians must check the printed identification, product packaging and network records.
The transmission distance available over OM4 depends on the Ethernet or Fibre Channel application, transceiver type and complete channel loss. As a result, the patch lead must form part of a properly designed link rather than being selected by connector type alone.
Singlemode CS connectors may use Ultra Physical Contact or Angled Physical Contact end faces. These formats are commonly described as UPC and APC.
A UPC connector uses a polished physical-contact end face without the angled geometry of APC. It suits many data communications and telecommunications applications.
An APC connector uses an angled end face to reduce reflected optical power. Therefore, APC can suit applications that require stronger return-loss performance.
However, UPC and APC connectors must not be mated together. Their end-face geometries do not align correctly. Consequently, a mixed connection can produce excessive loss, poor return loss and possible end-face damage.
The equipment interface determines the required polish. Therefore, customers should verify the transceiver, adaptor or device specification before ordering.
Connector colour may help with identification. Green commonly indicates APC, while blue commonly indicates UPC singlemode connectivity. Nevertheless, technicians should not rely on colour alone because housings and tabs can vary.
Multimode CS connectors do not use APC geometry in the same way as singlemode assemblies. Therefore, the fibre and polish selection must follow the actual optical application.
Insertion loss measures the optical power lost when a component enters the optical path. Every connector pair, splice and length of fibre contributes some loss to the complete link.
A high-quality CS patch lead should provide controlled connector loss. However, the measured loss of an installed connection depends on both mating connectors, their cleanliness, fibre alignment and test method.
Low insertion loss provides several benefits:
Nevertheless, connector specifications should not be confused with the measured loss of a complete patch lead. A connector manufacturer may publish performance based on controlled random-mating tests. Meanwhile, an assembled lead may receive end-to-end testing under a different method.
For this reason, customers should compare like-for-like specifications. They should also review the complete optical budget rather than focusing on one connector value.
Return loss describes how effectively a connection limits reflected optical power. Higher return-loss values generally indicate less reflected power returning towards the source.
Reflections can affect some high-performance singlemode systems. Therefore, connector polish, fibre contact and end-face quality matter.
APC connectors generally provide stronger return-loss performance than UPC connectors. However, APC only offers this advantage when the entire interface uses compatible APC geometry.
Contamination can also reduce return-loss performance. For example, dust or residue can prevent complete physical contact between ferrules. Consequently, even a correctly specified connector may perform poorly when dirty.
Therefore, inspection and cleaning remain critical parts of installation and maintenance.
A duplex optical link normally uses one fibre for transmission and one fibre for reception. Therefore, the transmitter at one end must connect to the receiver at the opposite end.
CS places both fibres inside one connector body. However, the network still requires correct transmit-and-receive polarity. The compact housing does not correct a crossed or incorrectly mapped link.
Polarity should remain controlled across:
Before installation, the designer should document the required fibre mapping. Afterwards, the installer should verify continuity and polarity.
If the link does not establish, technicians should avoid randomly reversing components. Instead, they should trace the complete channel and confirm the intended transmit-and-receive path.
High-density connectivity creates a practical handling challenge. As more connectors occupy the same panel area, technicians have less room to grip each connector.
The CS connector addresses this issue with an integrated push-pull tab. Therefore, a technician can connect or disconnect the lead by operating the tab from behind the connector.
This mechanism can:
However, technicians must use the mechanism correctly. Pulling the cable jacket can transfer force to the termination and fibre. Similarly, twisting the tab or pulling at an angle may damage the connector.
Before disconnecting a lead, the technician should identify both ends and confirm that the correct service can be interrupted. Dense panels increase the risk of selecting the wrong connection. Therefore, clear labels and current records become especially important.
Data centres continue to increase switch capacity, server density and optical port counts. Consequently, front-panel space and rack space have become valuable resources.
CS patch leads can support high-density data centre designs by reducing the footprint of each two-fibre connection. Applications may include leaf-and-spine architectures, high-density distribution frames, equipment patching and selected high-speed transceiver interfaces.
LC-to-CS assemblies can also help during staged upgrades. For example, an existing LC-based structured cabling system may remain in service while new equipment introduces CS ports. Therefore, the organisation can update active equipment without immediately replacing the permanent cabling.
However, a data centre should evaluate more than port density. Cable-management capacity, access, labelling, cleaning, testing and replacement procedures must also support the denser arrangement.
Higher density can magnify operational mistakes. One incorrectly labelled or contaminated connector can affect a critical service. Therefore, network owners should combine CS connectivity with disciplined fibre management.
Telecommunications networks require reliable, repeatable optical connections. At the same time, central offices, exchanges, roadside cabinets and equipment platforms may provide limited physical space.
CS patch leads can support suitable telecommunications equipment where high-density two-fibre interfaces are required. Moreover, OS2 singlemode fibre aligns with the long-distance and wavelength-based technologies commonly used across carrier networks.
Potential applications include:
Nevertheless, the environmental conditions must suit the patch lead construction. Standard indoor patch leads should not be exposed to water, uncontrolled outdoor conditions or mechanical abuse.
Enterprise networks may use CS connectivity as higher-density switches and equipment enter the market. For example, a large campus, hospital, university or corporate network may need to increase optical port density within an existing communications room.
Hybrid LC-to-CS leads can simplify such upgrades. The installed building backbone may continue to terminate on LC adaptors, while the new switch uses CS interfaces. Consequently, the patch lead becomes the transition between the two formats.
However, enterprises should assess replacement availability and technician familiarity before adopting a new connector platform. Spare leads, cleaning tools, inspection capability and documentation should all support CS connectivity.
A controlled introduction may provide the best outcome. For example, the organisation can deploy CS within a defined equipment zone while retaining LC across the wider structured cabling system.
Cloud and hyperscale facilities operate large numbers of optical links. Therefore, small improvements in connector density can create substantial benefits across thousands of connections.
CS technology can help manufacturers and operators increase the number of Base-2 optical channels within high-density panels and equipment. Moreover, selected transceiver designs can use multiple CS connections to organise high-speed optical lanes.
However, hyperscale terminology should not imply that CS only suits the world’s largest facilities. Smaller data centres and enterprise networks may also benefit where space and port density matter.
Conversely, not every network requires maximum density. Where equipment already uses LC and panel capacity remains sufficient, conventional LC patch leads may provide a simpler choice.
CS connectors have been developed with next-generation data rates and compact transceiver formats in mind. Selected QSFP-DD, OSFP and SFP-DD solutions may incorporate CS interfaces.
In these applications, multiple two-fibre CS connections can provide access to individual optical channels. Consequently, the equipment can combine high transceiver capacity with manageable Base-2 connectivity.
However, terms such as 200G, 400G or 800G describe aggregate data rates rather than a universal connector arrangement. Different transceivers can use duplex LC, CS, SN, MPO/MTP or other optical interfaces.
Therefore, customers must verify:
A CS patch lead cannot make incompatible transceivers communicate. Instead, it provides the physical optical connection required by equipment designed for the CS interface.
Anderson Corporation’s CS patch lead offering uses compact cable suitable for the connector and intended application. The current product information identifies a 2.0 mm round cable construction.
A compact round duplex cable can reduce congestion within high-density cabinets. Moreover, the shared jacket keeps both fibres together and supports orderly routing.
However, smaller cable does not mean that technicians can handle it carelessly. Installers should avoid:
Hook-and-loop straps generally provide better control than tightly fastened nylon cable ties. In addition, horizontal and vertical managers should support the cable without forcing sharp turns.
Technicians should also route enough slack for maintenance. However, excessive slack can obstruct airflow and complicate tracing. Therefore, cable length should match the actual pathway.
A suitable CS patch lead must match both the physical interfaces and the optical system.
Determine whether the link requires:
Do not rely on a general description such as “small duplex connector.” Instead, inspect the equipment specification or connector label.
Choose OS2 for compatible singlemode applications or OM4 for compatible multimode applications. The fibre must match the installed cabling and transceivers.
For singlemode links, verify the required end-face geometry at both interfaces. Never connect UPC directly to APC.
Confirm how the two fibres map from one connector to the other. This step becomes especially important for LC-to-CS assemblies.
Measure the intended route through the cable managers. Then, allow sufficient service slack without creating large coils.
Consider the total loss from patch leads, adaptors, permanent cabling, splices and other passive components. The completed link must remain within the transceiver budget.
Verify that the patch lead will operate indoors within its rated temperature and handling conditions. If the route includes exposed or harsh areas, consult Anderson Corporation about a suitable construction.
Determine whether the project requires insertion-loss results, polarity verification, serialised records or other documentation.
Clear ordering information helps prevent incompatible or incorrectly configured assemblies.
When requesting a quotation, specify:
A typical description may read:
CS UPC to CS UPC, OS2 duplex, 2.0 mm round cable, 2 metres
Alternatively:
LC UPC to CS UPC, OS2 duplex, 2.0 mm round cable, 3 metres
For multimode:
LC to CS, OM4 duplex, Erika Violet RAL 4003 jacket, 2 metres
Custom requirements should be discussed before manufacture. Moreover, high-volume projects should confirm one approved sample or configuration before the full order proceeds.
A controlled installation process protects optical performance and reduces the risk of service disruption.
First, check the connector types, fibre type, polish, length and labels. Also confirm that the assembly matches the intended equipment.
Next, look for signs of crushing, moisture or mishandling. If the packaging has suffered damage, inspect the lead carefully before use.
Then, inspect both connector end faces with suitable equipment. Clean them when required and reinspect before connection.
Keep dust caps fitted until the lead is ready to connect. However, do not assume that a newly uncapped connector is clean.
Orient the connector with the receptacle before insertion. Never force it into the port.
Push the connector into the correct CS interface until it engages. Afterwards, check that the connector sits securely.
Use the designated cable managers and maintain the required bend radius. Also protect the lead from doors, sharp edges and equipment trays.
Identify the circuit, destination and port according to the site standard. Dense panels particularly benefit from clear, durable labels.
Finally, complete the required continuity, polarity and insertion-loss testing. Record the results where the project requires formal documentation.
Contamination remains one of the most common causes of fibre connection problems. Even a small particle can block part of the fibre core, prevent proper physical contact or damage both mating surfaces.
Therefore, technicians should follow an inspect-clean-inspect-connect process.
First, inspect the CS ferrules with an inspection system and adaptor suitable for the connector. If contamination appears, use an approved cleaning method. Then, inspect the end face again before mating.
Both sides of a connection require attention. Cleaning only the patch lead does not correct contamination inside the adaptor, transceiver or equipment receptacle.
Technicians should avoid:
A contaminated connector can transfer debris to a clean one. Therefore, one poor maintenance decision can affect several components.
Testing confirms that the assembly and completed channel meet the project requirements.
Inspection identifies dust, oils, scratches and other end-face defects. Therefore, it should occur before mating and whenever a connection experiences unexpected loss.
A continuity check confirms that light passes through each fibre. However, continuity alone does not establish acceptable insertion loss.
Polarity testing confirms that the transmit and receive paths map correctly. This test becomes especially important for hybrid LC-to-CS assemblies.
Insertion-loss testing measures the optical loss across the patch lead or completed link. The test method, reference leads and interfaces should suit the installed connector types.
An OTDR can help characterise longer fibre links and identify reflective events. However, it does not replace a properly conducted insertion-loss test for every acceptance requirement.
Testing procedures should follow the project specification and relevant standards. Furthermore, test equipment must use suitable launch leads, receive leads and connector interfaces.
A CS connector cannot mate with an LC adaptor. Therefore, visually similar connector sizes should never substitute for positive identification.
Mating different end-face geometries can cause high loss and damage. Consequently, technicians must check the polish before connection.
An OS2 patch lead should not replace OM4 within a multimode channel, or vice versa. The connector may fit, yet the optical system may not perform correctly.
Incorrect fibre mapping prevents the transmitter from reaching the corresponding receiver. Therefore, polarity should be verified rather than guessed.
Dust, oil and residue can create high or unstable loss. Inspection and cleaning usually provide the first diagnostic step.
Tight bends can increase attenuation. Moreover, severe bending may permanently damage the cable.
Pulling on the jacket can stress the termination. Therefore, technicians should use the connector’s push-pull mechanism.
A cable that is too short places tension on the connectors. Conversely, an excessively long lead can obstruct airflow and complicate management.
A high-speed transceiver may use a different connector despite having a similar application. Therefore, the exact manufacturer specification must govern selection.
Higher density improves space efficiency, but it also increases the need for disciplined management.
Each lead should carry a unique and readable identifier. Moreover, records should show the connection at both ends, the fibre type and the service supported.
Technicians should separate active patch leads from abandoned cables. Otherwise, unused leads consume management capacity and restrict access.
Patch leads should also follow defined routes. Random routing across adaptor faces can obstruct the push-pull tabs and make later maintenance difficult.
Before removing a lead, the technician should trace and verify it. Afterwards, records should be updated immediately.
Spare CS leads should remain capped, packaged and labelled. In addition, the organisation should keep the connector-specific inspection and cleaning tools required for maintenance.
A patch lead may appear simple, yet its performance depends on precision manufacturing. Fibre preparation, ferrule geometry, polishing, alignment, crimping and cable strain relief all affect reliability.
A suitable CS assembly should provide:
However, product quality cannot compensate for poor installation. Excessive pulling, contaminated interfaces or incorrect mating can undermine even a well-manufactured lead.
Therefore, Anderson Corporation supports a complete approach that combines product selection, correct ordering, disciplined installation and appropriate testing.
Many organisations already have extensive duplex LC infrastructure. Therefore, adopting CS does not necessarily require a complete cabling replacement.
LC-to-CS patch leads can provide a controlled transition between the installed LC environment and new CS equipment. This approach may preserve permanent cabling, panels and cassettes while allowing selected active equipment to change.
A migration plan should identify:
A staged migration can reduce disruption. For example, one equipment row or network zone may adopt CS first. The organisation can then evaluate installation, maintenance and operational outcomes before expanding the platform.
Nevertheless, unnecessary connector transitions should be avoided. Every mated connection adds some optical loss and creates another point that requires cleaning and management.
CS patch leads may provide a strong solution when:
Conversely, standard duplex LC leads may remain the better choice when:
The correct decision should follow the equipment and network design. Therefore, connector density should support the wider operational requirement rather than become an objective by itself.
Anderson Corporation supplies fibre optic connectivity for Australian data centres, telecommunications networks, enterprise infrastructure and specialist applications.
Our CS patch lead service helps customers define the complete assembly rather than selecting a connector in isolation. Consequently, we can review the connector combination, fibre type, polish, polarity, cable length and application before manufacture.
Customers can benefit from:
Where a conventional connector provides the better solution, customers can also review the wider RapidConnect Fibre Optic Patch Leads range. This range covers established connector formats for general network patching.
