## Summary description

The BlueOptics SFP3131FU2MK is a 2 m InfiniBand fibre optic cable featuring LC connectors and OM4 fibre type. With a core diameter of 50 µm, it ensures high-speed data transmission suitable for data centers and high-performance computing environments.

## Long description

BlueOptics SFP3131FU2MK is a 2 meter duplex fiber optic patch cord with LC/UPC to LC/UPC connectors and laser-optimized multi-mode OM4 fiber (G50/125 µm) in magenta. Designed for 850 nm transmission, this OM4 LC-LC cable is suitable for connecting patch panels, optical transceivers and InfiniBand links in data centers and high-performance computing environments. The cable uses an LSZH flame-retardant jacket to reduce smoke and eliminate halogen release.
Advantages
The cable offers low attenuation (specified as 2.5 dB/km), low insertion loss and high return loss; connector end-face polishing can be optimized (UPC or 8° APC) to further improve return loss. High-quality branded fibers (e.g., Corning, Fujikura, YOFC) and precision connectors from recognized manufacturers are used, with zirconia ceramic ferrules rated for up to 1500 mating cycles. Each assembly is tested with interferometer and OTDR and shipped with a measurement protocol for insertion loss and return loss. The product meets Telcordia GR-326-Core requirements and relevant IEC and RoHS standards, and is covered by a 25-year functional warranty with a next-day exchange option for replacements.
Suitable for
Connections between optical transceivers (LC to LC)
Patch panel to patch panel or patch panel to transceiver links
InfiniBand and high-speed data center uplinks
Short-range multimode applications at 850 nm

Standards: Telcordia GR-326-Core, IEC-61034, IEC-754-1, IEC 60332-1, IEC 60332-3, IEC/EN 60950, RoHS
How to use
Inspect connector end-faces for cleanliness before making connections. Align and insert the LC duplex connectors into compatible LC ports on patch panels, transceivers or network equipment until they click into place. Avoid tight bends and maintain the manufacturer-recommended minimum bend radius for OM4 multimode fiber during installation and routing to prevent increased attenuation or damage. For troubleshooting, use the included measurement protocol values as reference.
Usage recommendations
Store and handle the cable in a clean environment; use dust caps on unused connectors. For best performance in data center or HPC environments, keep cable runs within recommended multimode distance limits for OM4 and avoid mechanical stress or sharp bends.
