BlueOptics SFP3131EU20MK InfiniBand fibre optic cable 20 m LC Aqua

The BlueOptics SFP3131EU20MK InfiniBand fibre optic cable is a 20 m LC–LC duplex patch cord designed for high-speed multimode links. Constructed with OM3 laser-optimized multimode fiber (50/125 µm, aqua), the cable supports full-duplex transmission at 850 nm and is intended for use with InfiniBand ports, transceivers and patch panels. The cable features LSZH (low-smoke zero-halogen) outer jacketing for reduced smoke and no halogen release in case of fire, and is produced from branded glass and connector components to ensure consistent optical performance.

Advantages

The OM3 multimode core and LC/UPC connectors deliver low attenuation (approximately 3.5 dB/km) and high return loss, supporting reliable short-range high-bandwidth links. Factory testing with interferometer and OTDR ensures measured insertion loss and return loss values are documented and included with each cable. Durable zirconia ferrules and quality connector manufacturing provide long mating life and stable connections, while the LSZH jacket improves safety in enclosed installations.

Suitable for

• InfiniBand uplinks and mid-range data center connections
• Connections between optical transceivers and patch panels or switches
• Short-reach high-speed multimode networks using 850 nm optics
• Installation environments requiring low-smoke, zero-halogen cabling

How to use

Route the 20 m LC–LC cable between the InfiniBand port or optical transceiver and the corresponding patch panel or switch port. Ensure connectors are clean and free of dust before insertion to avoid increased insertion loss; use appropriate fiber cleaning tools if necessary. Insert the LC duplex plug(s) until the latch engages and secure any strain relief or cable management to prevent tension on the connectors. Follow standard safety practices for fiber handling and avoid tight bends; maintain the cable bend radius recommended by the manufacturer.

Usage recommendations

Store the cable coiled loosely to avoid kinks, use LC dust caps when connectors are not in use, and verify optical link parameters after installation using appropriate test equipment. For installations requiring other lengths or connector types, consider ordering custom-length patch cords to minimize excess slack and optimize routing.
