Cables Direct FB4M-LCLC-050D OM4 5m LC-LC Aqua Fibre Optic Cable

Cables Direct FB4M-LCLC-050D | OM4 LC-to-LC Fibre Optic Cable

The Cables Direct FB4M-LCLC-050D fibre optic cable 5 m LC OM4 Aqua colour is a multi-mode patch lead for short-to-medium runs. It suits data centre racks and structured cabling in UK offices. Because it uses LC connectors, it fits modern network equipment with SFP+ ports. The aqua jacket clearly identifies OM4 performance. This cable is intended for 10G, 40G and 100G links over short distances. It supports 850 nm and 1300 nm wavelengths.

This exact model is a 5 metre LC-to-LC OM4 patch cable in aqua. It uses a 50 µm core with 125 µm cladding. The LSZH jacket reduces smoke and halogen in fire events. It is designed for indoor use in UK installations.

OM4 bandwidth for higher-speed links

OM4 offers greater bandwidth than OM3 over short runs. In practice, this supports 10G, 40G and 100G links. Because it is multi-mode, distance is limited compared with single-mode. For example, 100G using SR4 can reach around 100–150 m on OM4. Always confirm your switch transceiver standards before purchase.

LC connectors for high-density patching

LC connectors provide precise alignment and compact footprint. They suit SFP+ and QSFP ports found in modern switches. So you can patch cleanly in rack enclosures and panels. Also, the male connector gender is common for direct equipment links. If your panel uses female ports, confirm polarity and adapter needs.

LSZH jacket for indoor safety

The LSZH jacket limits smoke and halogen during combustion. This is suitable for UK indoor cable routes and risers. However, you must confirm local fire regulations for your building. Never assume compliance unless stated by the manufacturer or building specifier.

Aqua colour for OM4 identification

The aqua jacket follows common OM4 colour coding. This helps technicians identify fibre type quickly during audits. It reduces the risk of mixing OM3 and OM4 links. Also, it supports neat labelling in busy patch panels.

Precision performance specifications

This cable lists insertion loss at 0.3 dB and return loss at 35 dB. These figures support reliable link budgets for short runs. However, total loss depends on transceivers and connectors in the path. Always verify your transceiver power budget and link distance.
