## Summary description

The BlueOptics SFP3131EU5MK is a 5-meter InfiniBand fibre optic cable featuring LC connectors and OM3 fibre type. It supports full duplex communication and has a core diameter of 50 µm, making it ideal for high-speed data transmission in data centers and networking environments.

## Long description

BlueOptics SFP3131EU5MK is a 5 meter duplex fiber optic patch cord with LC/UPC to LC/UPC connectors, laser-optimized multi-mode OM3 fiber (50/125 µm) and an aqua-colored, flame-retardant LSZH jacket. It is designed for 850 nm transmission and full-duplex connections between patch panels, optical transceivers and other networking equipment in data centers and enterprise networks. The cable is available in multiple lengths and meets common industry standards for optical performance and safety.
Advantages
The OM3 fiber provides laser-optimized performance with an attenuation of approximately 3.5 dB/km, low insertion loss and high return loss. Connectors use zirconia ceramic ferrules from reputable manufacturers to ensure long lifetime and up to 1500 mating cycles. Each cable is factory-tested with interferometer and OTDR and shipped with a measurement protocol documenting insertion loss and return loss. The LSZH jacket reduces smoke and halogen release in case of fire.
Suitable for
High-speed InfiniBand links and short-reach fiber connections
Interconnection of optical transceivers and patch panels
Data center backbone and server-to-switch cabling
Structured cabling in enterprise and campus networks

How to use
Inspect connectors and fiber ends before installation and ensure dust caps are removed just prior to mating. Route the patch cord without sharp bends or tight radii to avoid microbending losses; follow the minimum bend radius specified by the network equipment vendor. Plug the LC connectors into corresponding LC ports on transceivers or patch panels, maintaining correct polarity for duplex links. After installation, verify link performance using appropriate optical test equipment or the provided measurement protocol.
Usage recommendations
Please store and handle the cable in a clean environment, avoid touching ferrule endfaces, and replace dust caps when the cable is not connected. For custom lengths or different connector types request a special order; verify transceiver compatibility with OM3 multimode fiber for optimal results.
