CBO InfiniBand Active Optical Cable QSFP-AOC-20M-QN-BO — QSFP to QSFP, 20 m

CBO InfiniBand Active Optical Cable QSFP-AOC-20M-QN-BO — QSFP to QSFP, 20 m is a 20-metre fiber-based active optical link that connects two QSFP ports for high-speed InfiniBand environments. The cable combines optical fibers with integrated transceivers to deliver long-reach, low-latency connectivity while presenting standard QSFP electrical interfaces on both ends. It is intended for data centre and server interconnect applications where copper reaches are insufficient and fiber-based links are preferred for performance and signal integrity.

Advantages

The active optical design reduces signal attenuation and electromagnetic interference compared with copper alternatives, enabling stable high-bandwidth transmission over 20 metres. Integrated optics and electronics simplify installation by eliminating separate transceivers and fiber patch cords. Low latency and consistent performance make the cable suitable for demanding cluster computing and storage networks. The QSFP connector form factor maintains compatibility with standard QSFP ports and allows direct QSFP-to-QSFP connectivity without additional adapters.

Suitable for

• Rack-to-rack server connections in data centres
• Intra-rack links between high-performance compute nodes
• InfiniBand fabrics and high-throughput storage networks
• Clusters and HPC interconnects requiring low latency

Key specifications

• Cable type: Active Optical Cable (AOC)
• Connector type: QSFP to QSFP
• Length: 20 metres
• Interface: InfiniBand-compatible high-speed QSFP electrical interfaces
• Transmission characteristics: fiber-based, low latency, high bandwidth
• Installation: plug-and-play with integrated transceivers

How to use

Insert each QSFP connector into the corresponding QSFP port on the devices to be interconnected, ensuring proper orientation and that port latches engage. The integrated optics and electronics are powered by the QSFP ports, so no separate power or configuration is required for basic connectivity. Verify link status and negotiated speed on both endpoints after insertion and monitor for any port or link errors via the host management tools. When removing the cable, release the connector latch and withdraw the plug carefully to avoid stressing the fiber assembly.

Usage recommendations

For reliable operation, route the cable to avoid sharp bends and mechanical strain; maintain the manufacturer’s minimum bend radius and protect connectors from dust when not in use. Use the cable for rack-to-rack or intra-rack runs up to 20 m and confirm compatibility with your QSFP ports and InfiniBand equipment. Regularly inspect connector endfaces and clean with appropriate fiber-cleaning tools if contamination is suspected.
