BlueOptics SFP3333BU2MK InfiniBand fibre optic cable 2 m ST Yellow

The BlueOptics SFP3333BU2MK is a 2 m InfiniBand fibre optic patch cord with duplex ST/PC to ST/PC connectors and laser-optimized single-mode fibre (SMF) of type G.657.A1 (9/125 µm). Designed for reliable point-to-point connections, this yellow, 2‑metre cable supports optical transmission at 1310 nm and 1550 nm, and is fitted with a flame-retardant LSZH jacket for reduced smoke and no halogen release in case of fire. Each cable is factory-tested for insertion loss and return loss and shipped with a measurement protocol to document performance.

Advantages

The cable uses G.657.A1 single-mode fibre optimized for low bending loss and stable transmission, offering typical attenuation around 0.4 dB/km and low input loss. Durable zirconia ceramic ferrules and branded connector components provide high mating-cycle durability. The LSZH jacket limits smoke emission and avoids halogen gases. Every unit is verified by interferometer and OTDR to ensure consistent optical parameters and compliance with industry standards.

How to use

Route the BlueOptics SFP3333BU2MK cable between the two optical devices or between a patch panel and a transceiver, taking care to avoid tight bends and excessive tensile stress. Align and insert the ST connectors into the corresponding ST sockets until the connector latches. Verify optical link status on connected devices and, if required, check insertion loss and return loss against the enclosed measurement protocol. For best performance keep connectors clean and protected with dust caps when not in use.

Recommendations

Store and handle the cable following standard fibre-optic best practices: avoid bending below the specified minimum bend radius for G.657.A1, use proper cable management in racks and conduits, and clean connector endfaces before mating to maintain the low insertion loss and return loss values documented in the test report.
