## Summary description

The BlueOptics SFP3131EU2MK is a 2 m InfiniBand fibre optic cable featuring LC connectors. It uses OM3 fibre with a 50 µm core diameter, supporting full duplex communication for efficient data transfer.

## Long description

The BlueOptics SFP3131EU2MK is a 2 m InfiniBand fiber optic patch cord with duplex LC/UPC to LC/UPC connectors and laser-optimized multi-mode fiber (LOMMF) in OM3 (50/125 µm) rated fiber. Designed for 850 nm transmission, the aqua-colored cable supports full-duplex connections between patch panels, optical transceivers and other network equipment. The jacket is flame-retardant LSZH to limit smoke and avoid halogen release in case of fire.
Advantages
This OM3 LC–LC duplex cable offers low attenuation (3.5 dB/km), low insertion loss and high return loss. Connectors are fitted with zirconia ceramic ferrules and branded connector components to ensure reliable mating performance up to 1500 cycles. Production testing includes interferometer and OTDR measurements; each cable ships with a measurement report of insertion loss and return loss. The product conforms to Telcordia GR-326-Core 4.4 and common IEC and RoHS standards.
Suitable for
InfiniBand and short-range multimode optical links
Connections between optical transceivers and patch panels
Data center trunking and server interconnects
Applications requiring LSZH jackets for reduced smoke and no halogens

How to use
Inspect connectors and fiber ends for contamination before installation. Plug the LC connectors into corresponding duplex LC ports on transceivers or patch panels, ensuring correct polarity for transmit and receive paths. Avoid tight bends below the manufacturer’s recommended bend radius and secure the cable to prevent strain on connectors. If necessary, verify link performance with appropriate optical test equipment using the included measurement report as a reference.
Usage recommendations
For best long-term performance, store and handle the OM3 patch cord in a clean environment, clean connector end faces with approved fiber cleaning tools before mating, and choose cable lengths that minimize excess slack in high-density installations.
