## Summary description

The BlueOptics SFP3131EU1MK is a 1m InfiniBand fibre optic cable featuring LC connectors and OM3 fibre type. With a core diameter of 50 µm, it supports full duplex communication, making it ideal for high-speed data transfer in networking applications.

## Long description

BlueOptics SFP3131EU1MK is a 1 meter InfiniBand fibre optic patch cord with duplex LC/UPC to LC/UPC connectors and laser-optimized multimode fiber (LOMMF) in category OM3 (50/125 µm core). The aqua-colored cable is designed for 850 nm transmission and supports full-duplex connections between patch panels, optical transceivers or other fibre equipment. The jacket is low-smoke, zero-halogen (LSZH) for reduced smoke and no halogen release in case of fire.
Advantages
This OM3 LC–LC duplex cable provides low attenuation (3.5 dB/km), low insertion loss and high return loss. High-quality branded fibers and manufacturer connectors with zirconia ceramic ferrules ensure durable performance and up to 1500 mating cycles. Each cable is tested with interferometry and OTDR, and a measurement protocol for insertion loss and return loss is included with the product.
Suitable for
 InfiniBand and short-range high-speed data links
 Connections between optical transceivers and patch panels
 Data centre horizontal and rack-level fibre runs

How to use
Inspect connectors and cable for visible damage before installation. Align LC connectors with corresponding ports on transceivers or patch panels and insert until a click indicates mating. Use appropriate cable management to avoid tight bends and strain; maintain minimum bend radius per manufacturer guidance. For testing, verify insertion loss and return loss using test equipment and refer to the included measurement protocol.
Usage recommendations
Use this OM3 LC–LC duplex cable for short-reach, high-bandwidth links such as InfiniBand or server-to-switch connections. Store and install in environments that avoid excessive bending, tensile stress and contamination of connector endfaces. For custom lengths or bulk installs, consult the supplier for options and pre-test procedures.
