Fibre optic cable Alcasa LW-U803LC4 OM4 3 m, 2x LC to 2x LC, 50 µm, full duplex

Alcasa LW-U803LC4 OM4 multimode fibre optic cable, 3 m, is a full duplex LC-to-LC patch cord designed for short-range high-bandwidth optical links. The cable uses 50 µm core OM4 multimode fibre and is terminated with two LC connectors on each end for duplex transmission. It is intended for datacentre patching, server and switch interconnects, InfiniBand and Fibre Channel links, and other short-distance optical connections that require reliable multimode performance.

Advantages

This OM4 multimode cable provides increased bandwidth and improved modal dispersion characteristics compared with lower-grade multimode fibres, enabling higher data rates over short distances. The full duplex LC-to-LC termination ensures straightforward pairwise connections between equipment ports without additional adapters. The LSZH jacket reduces smoke and toxic gas emission in the event of fire, which is suitable for enclosed installations and areas with increased safety requirements. The 3 m length balances manageable cable routing with reach for typical rack-to-rack or equipment-to-equipment links.

Suitable for

• Datacentre patching and horizontal cabling
• Server-to-switch and switch-to-switch interconnects
• InfiniBand and Fibre Channel short-range links
• Short-distance optical transmission in enterprise and telecom environments

How to use

Inspect connector endfaces for contamination before installation and clean with approved fibre cleaning tools if necessary. Route the 3 m cable along cable trays or within racks, avoiding tight bends; respect the manufacturer’s minimum bend radius for multimode fibre. Insert LC connectors into corresponding duplex ports on equipment, ensuring proper orientation and secure latch engagement. Avoid strain on the connectors and secure excess cable to prevent movement during equipment servicing.

Usage recommendations

Use this OM4 LC-to-LC cable for short-range, high-speed multimode connections in racks and containment systems. For best performance, maintain clean connectors and observe bend radius and handling guidelines specific to multimode fibre; replace or re-clean connectors if insertion loss or link errors occur.
