CBO InfiniBand Active Optical Cable JNP-25G-AOC-20M-BO 25G SFP28 20 m

The CBO InfiniBand Active Optical Cable JNP-25G-AOC-20M-BO is a 20-metre SFP28 AOC designed for 25G InfiniBand links. This active optical cable converts electrical signals to optical transmission to deliver low-latency, high-bandwidth connections between switches, servers and storage within data centres. The 20 m length provides a mid-reach option for rack-to-rack or aisle-to-aisle interconnects while offering the electromagnetic isolation and reduced bulk typical of optical cabling.

Advantages

This active optical cable combines SFP28 compatibility with optical transmission to minimise signal degradation over longer copper runs, offering lower attenuation and improved crosstalk immunity. Its optical design reduces cable weight and thickness compared with equivalent copper assemblies, helping to improve airflow and simplify cable routing in dense installations. The AOC supports low-latency operation suitable for latency-sensitive applications and eliminates the need for separate transceivers and patch cords, simplifying deployment.

Key specifications

How to use

Install the AOC by inserting the SFP28 connectors into the compatible 25G SFP28 ports on network switches, host adapters or storage devices. Ensure devices are powered down or support hot-plug insertion per device documentation, then verify link status and negotiated speed through the equipment management interface. Route the cable to avoid tight bends and mechanical stress; maintain the recommended bend radius from the manufacturer and avoid kinking. For mixed equipment environments, confirm SFP28 compatibility and firmware requirements to ensure link stability.

Recommendations

Use the cable for mid-reach interconnects where copper is impractical due to electromagnetic interference or weight. Store and handle the AOC in anti-static conditions, avoid exposure to excessive heat, and follow rack-management best practices to preserve airflow and reduce cable strain. For full compatibility, check the host and switch documentation for supported SFP28 AOC modules and link settings.
