BlueOptics CAB-SMF-ST-LC-3-BO InfiniBand fibre optic cable 3 m G.657.A1

The BlueOptics CAB-SMF-ST-LC-3-BO InfiniBand fibre optic cable is a 3 m single-mode patch cable designed for high-speed data transmission and reliable optical links. It uses G.657.A1 laser-optimized single-mode fibre and combines LC and ST connectors to provide compatibility with a wide range of networking equipment and transceivers. The cable features an LSZH flame-retardant sheath and is manufactured and tested to meet common industrial quality standards for low attenuation and consistent return-loss performance.

Advantages

This 3 m LC–ST patch cable offers low attenuation across the optical path and high return-loss values appropriate for demanding InfiniBand and fibre network applications. Components include high-grade single-mode fibre and ceramic ferrules to ensure stable mating performance and up to 1500 mating cycles. Each cable is tested with interferometry and OTDR and supplied with measured input-loss and return-loss values to support predictable installation results.

Suitable for

• Connecting optical transceivers to patch panels or switches
• InfiniBand interconnects in data centres and HPC environments
• Single-mode fibre runs requiring LC to ST terminations
• Installations where low smoke zero halogen (LSZH) sheathing is required

Key specifications

• Fibre type: single-mode G.657.A1 (laser-optimized)
• Length: 3 metres
• Connector A: LC
• Connector B: ST
• Sheath: LSZH (low smoke zero halogen)
• Tested for input loss and return loss; OTDR and interferometer tested
• Durability: zirconia ceramic ferrule, up to 1500 mating cycles
• Standards: manufactured to applicable IEC and RoHS norms

How to use

Inspect connector endfaces for contamination before insertion and clean with appropriate fibre cleaning tools if required. Insert the LC connector into the LC port and the ST connector into the ST port ensuring correct orientation and secure latching. Route the cable to avoid sharp bends and tensile stress; maintain the specified minimum bend radius for G.657.A1 single-mode fibre. After installation, verify link performance using appropriate optical power meters or transceiver diagnostics and refer to the supplied measurement protocol for baseline input-loss and return-loss values.

Usage recommendations

Store the cable coiled without tight loops and avoid crushing. Use dust caps when connectors are not in use. For installations in enclosed or public spaces where halogen-free materials are required, the LSZH sheath makes this cable suitable; still comply with local fire codes and mechanical protection requirements. If lower return-loss values are needed, consult the supplier about alternative polish types or custom polishing options.
