## Summary description

The BlueOptics SFP3131GU1MK is a 1 m InfiniBand fibre optic cable featuring LC connectors. It utilizes OM5 fibre with a 50 µm core diameter, supporting full duplex communication. Ideal for high-speed data transmission in data centers and networking environments.

## Long description

The BlueOptics SFP3131GU1MK InfiniBand fibre optic cable is a 1 m duplex LC–LC patch cord built on OM5 laser-optimized multimode fiber (50 µm core). Designed for full-duplex InfiniBand and high-speed short-range links, this lime-green LC/UPC to LC/UPC cable supports 850 nm multimode transmission and is intended for connections between transceivers, patch panels and active equipment in data centers and network racks.
Advantages
This OM5 LC–LC duplex cable provides low attenuation and high return loss for reliable short-reach data transmission. Its LSZH (low smoke zero halogen) jacket reduces smoke and avoids halogen release in case of fire, meeting common industry safety standards. The cable is manufactured with branded multimode glass and zirconia ceramic ferrule connectors to ensure consistent optical performance and long connector life. Each unit is tested for insertion loss and return loss, and a measurement report is supplied.
Suitable for
InfiniBand links and short-range high-speed interconnects
Patch panel to transceiver or transceiver-to-transceiver connections
Data center uplinks and server rack fiber runs
Multimode 850 nm optical systems requiring OM5 performance
Key specifications
Fiber type: OM5 multimode, 50 µm core diameter

Color: lime green (OM5 standard color)
Duplex/full-duplex capable
How to use
Install the BlueOptics SFP3131GU1MK by aligning and inserting the LC connectors into corresponding LC ports on patch panels, transceivers or switches. Ensure connectors are clean before mating; fiber dust or contaminants can increase insertion loss. Route the cable following rack and cable management best practices to avoid tight bends — maintain the specified minimum bend radius. For reliable operation, use the supplied test report to verify insertion loss and return loss against your system requirements.
Usage recommendations
Clean connector endfaces with appropriate fiber cleaning tools before first use, avoid exceeding the cable minimum bend radius, and store or install in environments within the recommended temperature and humidity ranges. For critical links, validate end-to-end performance after installation using optical test equipment and keep measurement documentation for maintenance purposes.
