BlueOptics SFP3131BU7.5MK cavo in fibra ottica InfiniBand 7,5 m LC giallo

BlueOptics SFP3131BU7.5MK is a 7.5 meter duplex fibre optic patch cord with LC/UPC to LC/UPC connectors and laser‑optimized single‑mode G.657.A1 fiber (9/125 µm). The yellow cable is intended for InfiniBand and other high‑speed data transmission applications and features a flame‑retardant LSZH jacket. It supports transmission at common wavelengths such as 1310 nm and 1550 nm and is available in multiple lengths, with 7.5 m as the supplied length.

Advantages

The cable offers low attenuation (approximately 0.4 dB/km), low insertion loss and high return loss; connector end‑face polish options (UPC or 8° APC) allow further return‑loss optimization. High‑quality branded fiber and precision connectors with zirconia ceramic ferrules are used to ensure reliable, low‑loss connections and a long mating cycle life. Each cable is tested with interferometer and OTDR and shipped with a measurement protocol for insertion and return loss. The LSZH jacket reduces smoke and no halogens are released in case of fire.

Key specifications

How to use

Inspect connectors and ensure dust caps are removed before installation. Route the duplex LC cable between the transceivers or panel ports, observing fiber bend radius limits for G.657.A1 to avoid excess stress. Plug each LC connector into the corresponding LC receptacle until it clicks; ensure correct duplex orientation for transmit/receive pairs. After installation, verify link integrity using appropriate testing equipment and refer to the enclosed insertion loss and return loss measurement protocol.

Recommendations

Store and handle the patch cord without sharp bends, protect connector end‑faces from contamination, use LC dust caps when not connected, and follow standard cleaning procedures before mating. For installations in enclosed or populated spaces prefer LSZH jacketed cables to minimize smoke and toxic gas emission in case of fire.
