Cables Direct FB4M-LCLC-100D 10m LC OM4 Aqua fibre optic cable

Cables Direct FB4M-LCLC-100D | OM4 LC-to-LC Fibre Optic Cable

The Cables Direct FB4M-LCLC-100D fibre optic cable 10 m LC OM4 Aqua colour is built for high-speed data centre and enterprise backbone links. This 10-metre multi-mode patch lead uses LC connectors and OM4 fibre to support 10 Gbps, 40 Gbps, and 100 Gbps applications. It is intended for network engineers and IT facilities managers who need reliable, low-loss connections between switches, servers, and patch panels. The aqua jacket clearly identifies OM4 specification, aiding quick cable management. Because it uses low smoke zero halogen (LSZH) materials, it suits environments where fire safety is a priority.

Technical Specifications at a Glance

Optimised for OM4 Bandwidth and Distance

OM4 fibre offers higher bandwidth than OM3, supporting 10 Gbps up to 400 metres and 40 Gbps up to 150 metres. This 10-metre cable is ideal for short-reach rack-to-rack connections within a data hall. Because it operates at 850 nm and 1300 nm wavelengths, it fits standard multi-mode transceivers. In practice, this reduces latency and supports future-proof upgrades. You should verify that your SFP+ or QSFP modules are OM4-rated for full performance.

Low Smoke Zero Halogen (LSZH) Safety

The jacket is constructed from LSZH material, which emits minimal smoke and no halogen compounds when exposed to flame. This is critical for enclosed spaces like server rooms and under-floor ducts where air quality matters. However, compliance with UK building regulations is not specified; confirm local fire safety standards before installation. Always check that your facility’s cable containment supports LSZH approvals.

Precision LC Connectors for Dense Port Layouts

LC connectors provide a small form factor, enabling high port density on modern switches and patch panels. Both connectors are male, ensuring a secure push-pull latching mechanism. This design minimises accidental disconnections during maintenance. Because the cable is aqua-coloured, you can quickly distinguish OM4 fibre from OM3 or single-mode runs. Verify that your equipment ports are LC-based before ordering.

Consistent Insertion Loss for Reliable Links

With a maximum insertion loss of 0.3 dB, this cable maintains signal integrity across the 10-metre run. Low insertion loss is essential for power budget calculations in high-speed networks. For example, it helps ensure that your transceivers operate within their optical tolerance. However, always confirm your total link budget includes patch panels and couplers. This cable is intended for structured cabling environments.

Aqua Colour Coding for Quick Identification

The aqua colour is the recognised standard for OM4 multi-mode fibre, reducing installation errors. This visual cue helps technicians identify cable types during audits or upgrades. In practice, it speeds up troubleshooting and reduces downtime. Because the cable is 10 metres, it is suited for intra-rack or adjacent rack connections. You should verify the required length for your specific topology.

Check before you buy

• Confirm your network devices have LC multi-mode ports compatible with OM4 fibre.
• Verify the required cable length for your rack layout; 10 m may be excessive for single-rack setups.
• Check that your transceivers (SFP+, QSFP) support OM4 50 µm core at your target data rates.
• Ensure LSZH jacket material meets your facility’s fire safety and UK building regulations.

Frequently Asked Questions

Q: Is this cable compatible with OM3 equipment?

A: Yes, OM4 is backward compatible with OM3, but you will only achieve OM3 speeds unless both ends support OM4.

Q: Can I use this cable outdoors?

A: No, the LSZH jacket is designed for indoor use; confirm outdoor-rated alternatives if needed.

Q: Are the connectors polish types specified?

A: No, the input does not state UPC or APC polish; verify with the distributor before purchase.

Q: Does this cable support 100 Gbps links?

A: Yes, OM4 supports 100 Gbps up to 100 metres using SR4 optics; confirm your transceiver model.

Q: Is the cable UKCA or CE marked?

A: The input does not specify compliance marks; verify with the manufacturer or distributor for UKCA/CE status.
