BlueOptics CAB-SMF-LC-SC-7.5-BO InfiniBand fibre optic cable 7.5 m 2x LC LC/APC

The BlueOptics CAB-SMF-LC-SC-7.5-BO is a 7.5 m single-mode fibre optic cable designed for InfiniBand data links. It features G.657.A1 fibre with a 9 µm core diameter and 2x LC/APC connectors configured for full duplex transmission. The cable supports low insertion loss and return loss characteristics typical for APC-terminated single-mode links, making it suitable for demanding high-speed interconnects where signal integrity and minimal reflections are required.

Advantages

This fibre cable delivers stable single-mode performance over a short to medium reach with APC polish connectors to reduce back reflections. The G.657.A1 fibre specification provides improved bend resistance compared with older single-mode variants, allowing for more flexible routing in racks and conduit. Using LC/APC terminations ensures compatibility with equipment requiring angled physical contact connectors and helps maintain signal quality in InfiniBand environments.

How to use

Install the cable by connecting each LC/APC connector to the corresponding LC/APC port on your InfiniBand transceivers or patch panels, ensuring connectors are aligned and fully seated to avoid signal loss. Route the cable along rack cable management paths, avoiding sharp bends and crushing points; the G.657.A1 fibre allows tighter bend radii but standard good-practice routing should be followed. Before finalising the installation, inspect and, if needed, clean connector endfaces with appropriate fibre cleaning tools to maintain low insertion loss and return loss.

Recommendations

Regularly inspect connector endfaces and use dust caps when connectors are not in use. Maintain bend radii above the minimum recommended for G.657.A1 fibre, secure the cable to prevent strain on connectors, and match APC connectors with APC ports to ensure optimal return loss performance.
