## Summary description

The Alcasa LW-U820LC5 is a 20m InfiniBand fibre optic cable featuring LC connectors and OM5 fibre type. With a core diameter of 50 µm, it supports full duplex communication, ensuring efficient data transfer for high-performance networking applications.

## Long description

The Alcasa LW-U820LC5 InfiniBand Fibre Optic Cable 20m LC Green OM5 is a multimode fibre cable designed for high-performance data links in modern network environments. With LC connectors on both ends and OM5 multimode glass with a 50 µm core, the cable supports full duplex transmission and is suited to short- to medium-range interconnects in data centres, storage area networks and high-speed compute clusters.
Advantages
This 20 metre OM5 fibre cable provides predictable multimode performance with reduced modal dispersion compared to older multimode grades, enabling reliable high-bandwidth links. The LC terminations offer compact connector density and stable mating performance. The green jacket colour simplifies identification in complex cable runs and the cable construction supports low insertion loss and consistent optical characteristics for InfiniBand and other multimode applications.
Suitable for
Short- to medium-distance InfiniBand links in data centres
Connections between servers, switches and storage arrays
High-performance computing clusters and SAN environments
Upgrades from legacy multimode installations requiring higher modal bandwidth
Key specifications
Fibre type: OM5 multimode
Core diameter: 50 µm
Connector type: LC to LC
Length: 20 metres
Transmission mode: full duplex
Jacket colour: green
How to use
Ensure both ends are clean and free from dust or contaminants before mating the LC connectors with equipment ports. Route the cable to avoid tight bends and mechanical strain; adhere to the minimum bend radius specified by your infrastructure guidelines. Plug the LC connectors into the corresponding InfiniBand or multimode fibre ports until they click to secure the connection. Verify link status and throughput using the host or switch management tools and perform any necessary optical power checks.
Usage recommendations
Store and handle the OM5 multimode cable in a dust-free environment and use fibre cleaning tools for end-face maintenance. Avoid routing near strong electromagnetic interference sources and use proper cable management to prevent kinking. For optimal performance, match connector types and fibre grades across the link and follow vendor guidelines for insertion loss and return loss limits.
