Cables Direct FB2S-LCLC-050YD 5m InfiniBand Cable LC-LC Yellow

Cables Direct FB2S-LCLC-050YD | LC-LC OS2 Single-Mode Fibre

The Cables Direct FB2S-LCLC-050YD InfiniBand/fibre optic cable 5 m LC Yellow is a 5-metre OS2 single-mode patch lead. It connects network equipment using LC to LC connectors. This cable suits UK data centre and enterprise rack deployments requiring reliable 10 Gbit/s links. Its LSZH yellow jacket supports safer installation in confined spaces.

This cable uses a 9 µm core with 125 µm cladding for single-mode transmission. It supports 1310 nm and 1550 nm wavelengths with 0.3 dB insertion loss. The round 3 mm LSZH jacket is yellow for easy identification. Full duplex operation enables bidirectional data flow over one fibre pair.

Low Smoke Zero Halogen (LSZH) jacket safety

The LSZH jacket limits smoke and halogen emissions during fire events. This is important for UK offices and risers with strict building regulations. Because the cable is yellow, engineers can trace links quickly in dense patch panels. In practice, LSZH helps meet internal safety policies without compromising performance.

LC UPC connectors for precise signal integrity

The LC connectors feature UPC polish for consistent low return loss (50 dB). Because the connectors are male on both ends, verify your patch panel or SFP ports accept LC-LC links. So you avoid mismatched gender issues during installation. In practice, UPC polish supports stable 10 Gbit/s single-mode links.

10 Gbit/s single-mode performance over 5 metres

This cable supports 10 Gbit/s data transfer across the full 5 m length. It works with standard OS2 single-mode transceivers at 1310 nm or 1550 nm. Because insertion loss is 0.3 dB, link budgets remain healthy over longer runs. So it suits core-to-rack or cross-connect tasks in UK networks.

Full duplex operation for bidirectional traffic

Full duplex support allows simultaneous transmit and receive on the same fibre pair. This reduces cable count compared to simplex solutions. Because it uses OS2 single-mode, it offers future-proof capacity beyond 10 Gbit/s with appropriate optics. So you can scale without replacing the patch leads.

3 mm round cable diameter for tidy routing

The 3 mm round jacket supports neat cable management in trays and enclosures. Because the jacket is yellow, you can separate single-mode links from multimode or copper runs. In practice, this helps maintain airflow and compliance in UK racks. So patch panels stay organised and serviceable.

Frequently Asked Questions

Q: Is this cable compatible with standard SFP+ LR transceivers?

A: Yes, it pairs with OS2-rated single-mode SFP+ modules at 1310/1550 nm.

Q: Does the cable support 25 Gbit or 100 Gbit links?

A: It is rated for 10 Gbit/s; higher rates depend on transceiver and link budget.

Q: Can I use this in UK office risers?

A: The LSZH jacket suits risers, but confirm local fire regulations and building compliance.

Q: Are both connectors male?

A: Yes, both LC connectors are male; verify your patch panel or device ports accept LC-LC.

Q: What is the return loss performance?

A: Return loss is 50 dB, supporting stable single-mode signal integrity.

Q: Is the cable CE or UKCA marked?

A: Not specified; confirm certification with the distributor or manufacturer before installation.
