## Summary description

The BlueOptics SFP3131EU0.5MK is a 0.5 m InfiniBand fibre optic cable featuring LC connectors. It utilizes OM3 fibre optic type with a core diameter of 50 µm, ensuring full duplex communication. This cable is ideal for high-speed data transmission in data centers and networking applications.

## Long description

BlueOptics SFP3131EU0.5MK is a 0.5 meter duplex LC/UPC to LC/UPC OM3 (50/125 µm) multimode fiber patch cord in aqua color, designed for InfiniBand and other high-speed data connections. The cable uses laser-optimized multimode fiber (LOMMF) and an LSZH flame-retardant jacket. It transmits at 850 nm and is suitable for connecting patch panel ports, transceivers and other network equipment where short-run multimode fiber links are required.
Advantages
The cable offers low attenuation (3.5 dB/km), low insertion loss and high return loss. Connectors use zirconia ceramic ferrules from reputable manufacturers and are rated for up to 1500 mating cycles. Each patch cord is tested by interferometer and OTDR and supplied with a measurement protocol for insertion loss and return loss. The LSZH jacket reduces smoke and avoids halogen release in case of fire. The product complies with Telcordia GR-326-Core 4.4 and relevant IEC and RoHS standards.

How to use
Inspect connectors and ports for contamination before mating. Remove protective caps, align the duplex LC connectors with the matching ports and insert until secure. Use the supplied measurement protocol to verify insertion loss and return loss if required. For permanent installations route the cable to avoid sharp bends and mechanical stress; respect the minimum bend radius specified by the fiber manufacturer.
Usage recommendations
For reliable performance in data center and InfiniBand applications, use this OM3 duplex LC patch cord for short-reach links (within the supported attenuation and distance limits), keep connectors clean, and choose appropriate cable lengths to minimize excess slack and bending.
