BlueOptics CAB-SMF-ST-LC-5-BO InfiniBand fibre optic cable 5 m G.657.A1

The BlueOptics CAB-SMF-ST-LC-5-BO InfiniBand fibre optic cable is a 5 m single-mode patch cable designed for high-speed networking. It uses G.657.A1 laser-optimized single-mode fibre with a 125 µm core diameter and is terminated with an LC connector on one end and an ST connector on the other. The cable supports full-duplex optical communication and is intended for patching between patch panels, transceivers, and other optical ports in data centres and enterprise networks.

Advantages

This 5 m BlueOptics cable provides low attenuation per kilometre and high return-loss performance, supporting stable optical signals over typical short-distance campus and rack-level links. The cable is fitted with high-quality zirconia ceramic ferrules and connectors from established component manufacturers to ensure durability and repeatable mating performance. A flame-retardant LSZH outer jacket reduces halogen release and smoke generation in the event of fire, complying with common industry safety norms.

Suitable for

• Patch panel to patch panel connections in racks and cabinets
• Connecting optical transceivers (LC to ST) in switches and servers
• Short-range InfiniBand and single-mode network links within buildings

Key specifications

• Connector A: LC (UPC style)
• Connector B: ST (PC style)
• Core/cladding diameter: 125 µm (single-mode standard cladding)
• Duplex mode: Full duplex
• Jacket material: LSZH (flame-retardant, low smoke, zero halogen)
• Test methods: Interferometer and OTDR tested with measured input loss and return loss protocol

How to use

Route the BlueOptics CAB-SMF-ST-LC-5-BO cable between the two optical ports to be connected, ensuring bend radii are not violated and cable management is used to avoid sharp bends or kinks. Clean connector endfaces before mating using an appropriate fibre cleaning tool and inspect endfaces if possible. Insert the LC connector into the LC receptacle and the ST connector into the ST socket until secure. Verify optical link status on connected equipment and, if required, check insertion loss and return loss values against system tolerances using an OTDR or power meter.

Usage recommendations

Maintain minimum bend radius guidelines for single-mode G.657.A1 fibre, avoid repeated mechanical stress on connectorized ends, and store unused cables coiled without tight loops. Use compatible LC and ST ports and clean endfaces prior to each connection to preserve low attenuation and reliable performance over time.
