## Summary description

The BlueOptics SFP3131FU5MK is a 5 m InfiniBand fibre optic cable featuring LC connectors. It supports OM4 fibre type and full duplex communication, making it ideal for high-speed data transfer in data centers and networking applications.

## Long description

BlueOptics SFP3131FU5MK is a 5 meter duplex fiber optic patch cord with LC‑UPC to LC‑UPC connectors and laser‑optimized multimode fiber OM4 (G50/125 µm) in a magenta, low‑smoke zero‑halogen (LSZH) jacket. Designed for 850 nm transmission, this LC‑LC OM4 cable is suitable for connecting patch panels, InfiniBand or optical transceivers and other network equipment requiring full‑duplex multimode links. A measurement protocol with input loss and return loss values is included.
Advantages
The cable provides low insertion loss (input loss under 0.2 dB) and a typical attenuation of 2.5 dB/km, combined with high return loss. Ceramic zirconia ferrules and branded multimode fiber ensure consistent signal quality and long connector life. The LSZH jacket reduces smoke and avoids halogen release in case of fire, meeting common industrial safety norms. Each patch cord is tested with interferometer and OTDR and shipped with a test report.
Suitable for
Data center trunks and patch panel connections
InfiniBand and short‑reach multimode links (850 nm)
Connecting LC optical transceivers and active network devices

How to use
Inspect connectors and ports for dust before connecting. Align the LC duplex connectors with corresponding LC ports on patch panels or transceivers and insert until the latch clicks. For removal, press the LC latch and gently pull the connector out. Route the cable without sharp bends and avoid excessive tensile force; observe minimum bend radius recommended for OM4 multimode fiber.
Usage recommendations
Store and handle the patch cord in a clean environment; use dust caps when connectors are not in use. For critical links, verify measured insertion loss from the supplied measurement protocol and repeat testing after installation if required.
