## Summary description

The BlueOptics SFP3131FU0.5MK is a 0.5 m InfiniBand fibre optic cable featuring LC connectors and OM4 fibre type. It supports full duplex communication with a core diameter of 50 µm, ideal for high-speed data transfer in data centers and networking applications.

## Long description

BlueOptics SFP3131FU0.5MK is a 0.5 meter InfiniBand fiber optic patch cord with duplex LC/UPC to LC/UPC connectors and laser-optimized multi-mode OM4 fiber (50/125 µm core). The cable is designed for 850 nm transmission and supports full-duplex links between patch panels, switches and optical transceivers. The jacket is flame-retardant LSZH and the cord is available in multiple standard lengths; this unit is 0.5 m long and colored magenta for easy identification.
Advantages
This OM4 LC–LC duplex patch cord offers low attenuation (specified at 2.5 dB/km), low insertion loss and high return loss. Connectors use zirconia ceramic ferrules and branded fiber from established manufacturers to ensure consistent performance and long mating life. Each cable is factory-tested with interferometer and OTDR and delivered with a measurement protocol for insertion and return loss. The LSZH jacket reduces smoke and halogen release in case of fire and the product meets industry requirements including Telcordia GR-326-Core.
Suitable for
 High-speed InfiniBand links in data centers
 Connections between optical transceivers and patch panels
 Short-reach multimode applications requiring OM4 performance

How to use
Route the cable between LC ports of devices or patch panels ensuring both ends are clean and free of dust before mating. Align the duplex connectors with the keyed ports and insert until the latch clicks. Avoid tight bends and secure the cable to prevent strain on the connectors. For best optical performance, use the supplied measurement protocol to verify insertion and return loss after installation.
Usage recommendations
Clean connector endfaces with appropriate fiber cleaning tools before each connection and avoid exposing the cable to mechanical stress; store unused connectors with dust caps. Use OM4 cabling for applications that require higher modal bandwidth and improved short-reach performance compared with lower multimode categories.
