BlueOptics SFP3131BU0.5MM InfiniBand fibre optic cable 0.5 m LC

BlueOptics SFP3131BU0.5MM is a 0.5 m duplex fibre optic patch cord with LC/APC to LC/APC (8° angled polish) connectors and laser-optimized single-mode G.657.A1 fiber (9/125 µm). The cable is intended for InfiniBand and other high-speed networking applications and is suitable for connecting patch panels, optical transceivers or other LC/APC ports. The jacket is flame-retardant LSZH and the cable is delivered in yellow.

Advantages

The cable provides low attenuation (0.4 dB/km) with low insertion loss and high return loss, enabling reliable long-distance single-mode transmission at 1310 nm and 1550 nm. Manufactured using branded fibers and precision connectors, it is built for repeatable, low-loss mating cycles and comes with a measurement protocol for insertion and return loss. The LSZH jacket reduces smoke and avoids halogen emissions in case of fire.

Suitable for

• Connecting optical transceivers to transceivers (duplex links)
• Patch panel-to-patch panel or patch panel-to-transceiver connections
• InfiniBand and other high-speed single-mode network links
• Installations requiring flame-retardant, low-smoke cabling

How to use

Inspect connector endfaces and ensure dust caps are removed before connection. Plug LC/APC connectors into matching LC/APC ports with the keyed orientation and secure patch panel or transceiver ports as required. Route the cable without tight bends, avoiding strain on the connectors and keeping bend radius within manufacturer recommendations. For critical links, verify insertion loss and return loss using test equipment and retain the supplied measurement protocol with the installation records.

Usage recommendations

Store and install the cable in clean conditions, avoid contamination of endfaces and routinely clean connectors with appropriate fiber cleaning tools. Select appropriate cable length to minimise stress and maintain bend radius; request custom lengths if needed. Use LSZH cabling in areas where low smoke and halogen-free behaviour is required.
