## Summary description

The Gembird CFO-MDOM4-LC/LC-25M is a 25m LC/UPC fibre optic cable designed for high-speed data transmission. It features OM4 fibre type with a core diameter of 50 µm and full duplex capability, making it ideal for InfiniBand applications. This cable ensures reliable performance and is suitable for various networking needs.

## Long description

The Gembird CFO-MDOM4-LC/LC-25M InfiniBand fibre optic cable LC/UPC 25m OM4 is a 25-metre multimode fibre assembly engineered for high-throughput, low-latency connections. It uses OM4 multimode fibre with a 50 µm core diameter and LC/UPC connectors on both ends for full-duplex InfiniBand and other high-performance networking environments. The cable is intended to provide stable optical transmission over short to medium distances, supporting data centre interconnects, switch-to-switch links and other rack-level fibre links.
Advantages
This OM4 fibre cable offers higher bandwidth and improved modal performance compared with lower-grade multimode fibres, enabling higher data rates and extended reach for multimode links. The LC/UPC terminations provide low insertion loss and consistent connector performance. The 25 m length gives flexibility for rack-to-rack or room-to-room deployments without the need for splices. The design supports full-duplex operation required by InfiniBand systems and similar high-speed fabrics.
Suitable for
InfiniBand host and switch connections requiring full-duplex multimode links
Data centre rack-to-rack optical interconnects
High-performance computing clusters and storage area networks
Server room cabling and network equipment interlinks
Key specifications
Fibre type: OM4 multimode fibre
Core diameter: 50 µm
Connector type: LC/UPC to LC/UPC
Cable length: 25 metres
Mode: Full duplex (duplex multimode)
Typical use: Short- to medium-range high-speed optical links
How to use
Inspect both LC/UPC connectors and the fibre ends for contamination before installation; clean connectors with proper fibre cleaning tools if necessary. Route the cable through cable management channels or trays to avoid sharp bends and excessive tensile stress, observing the manufacturer’s minimum bend radius for multimode fibre. Insert each LC connector into the corresponding LC port until it clicks, ensuring correct orientation for transmit and receive pairs to establish full-duplex links. Verify optical link status and perform basic optical power or link tests as appropriate for the InfiniBand or networking equipment in use.
Usage recommendations
Store and handle the fibre cable in a dust-free environment when possible; avoid bending the cable beyond its rated minimum radius and protect LC/UPC connectors with dust caps until final assembly. For reliable long-term performance, perform connector cleaning and periodic inspection, and use labelled cable management to maintain correct port mapping in dense installations.
