## Summary description

The Gembird CFO-MDOM4-LC/LC-20M is a 20m long fibre optic cable featuring LC/UPC connectors and OM4 fibre type. It supports full duplex communication with a core diameter of 50 µm, making it ideal for high-speed data transmission in InfiniBand applications.

## Long description

The Gembird CFO-MDOM4-LC/LC-20M InfiniBand fibre optic cable is a 20-metre duplex patch cable with LC/UPC connectors and OM4 multimode fibre. Designed for high-speed data transmission, this cable uses 50 µm core diameter fibre and supports full duplex communication, making it suitable for InfiniBand links, data centre interconnects and other short- to medium-range high-bandwidth connections.
Advantages
This OM4 fibre cable provides improved modal bandwidth and lower attenuation compared with lower-grade multimode fibres, enabling higher data rates and longer reach in multimode deployments. The LC/UPC connectors deliver reliable, low-loss connections suitable for dense port environments. With a 20 m length, the cable offers flexible routing options while maintaining signal integrity for InfiniBand systems and other high-performance networks.
Suitable for
InfiniBand server and switch interconnects
Data centre patching and rack-to-rack links
High-speed storage area networks (SAN)
Short- to medium-range multimode Ethernet links
Key specifications
Length: 20 m
Connector type: LC/UPC to LC/UPC, duplex
Fibre type: OM4 multimode
Core diameter: 50 µm
Operation: full duplex
How to use
Connect each LC/UPC connector to the corresponding LC port on your InfiniBand host channel adapters, switches or transceivers, ensuring correct polarity for duplex links. Route the cable through cable management trays or rack channels to avoid sharp bends; observe minimum bend radius recommendations from your equipment vendors. Inspect connector endfaces before insertion and clean with appropriate fibre cleaning tools if necessary to minimise insertion loss.
Usage recommendations
For reliable performance, store and handle the OM4 cable in a manner that prevents kinks and excessive bending. Use dust caps when connectors are not mated, and perform regular inspections of connector endfaces. Choose transceivers and equipment ports compatible with OM4 multimode fibre and LC/UPC terminations to achieve the expected data rates and reach.
