## Summary description

The BlueOptics SFP3131FU50MK is a 50 m InfiniBand fibre optic cable with LC connectors. It features OM4 fibre type and a core diameter of 50 µm, ensuring full duplex communication for high-speed data transfer.

## Long description

The BlueOptics SFP3131FU50MK is a 50 m InfiniBand multimode fibre optic patch cord with duplex LC/UPC to LC/UPC connectors and OM4 (G50/125 µm) fibre. It is designed for full-duplex 850 nm transmission and connects patch panels, optical transceivers, or other fibre ports over a 50 metre link. The cable uses a flame-retardant LSZH jacket and is available in a magenta colour for easy identification in data centre and cabling environments.
Advantages
This OM4 multimode patch cord provides low attenuation (approximately 2.5 dB/km) and high return loss for reliable high-speed links. Connectors are fitted with zirconia ceramic ferrules and brand-name components to ensure low insertion loss and long service life. The cable assembly is factory-tested using interferometry and OTDR, and a measurement report for insertion loss and return loss is supplied with each unit. The LSZH jacket reduces smoke and eliminates halogen release in the event of a fire, aligning the cable with common safety standards.
Suitable for
High-speed InfiniBand connections between servers, switches and storage
Data centre horizontal and rack-to-rack interconnects
Connecting optical transceivers and patch panels using LC duplex ports
Key specifications

How to use
Unpack the patch cord and inspect connectors and dust caps before installation. Remove dust caps only when ready to connect. Route the cable following standard cable management practice to avoid tight bends and mechanical stress; maintain the manufacturer’s minimum bend radius for OM4 multimode fibre. Insert each LC connector into the corresponding duplex LC port or transceiver until it clicks and secure any patch panel retainers if present. Verify link integrity and optical performance using appropriate test equipment or by checking device link/activity indicators.
Usage recommendations
For best performance, store and handle the cable in a clean environment, keep connectors capped when not in use, and avoid kinking or excessive bending. Use this OM4 50 m LC–LC duplex patch cord where low-loss, high-bandwidth multimode links are required; verify transceiver compatibility with OM4 multimode and 850 nm operation prior to deployment.
