AOC CBO QSFP-100G-AOC-20M 20m QSFP28 active optical cable for 100G networks

The AOC CBO QSFP-100G-AOC-20M is a 20-meter QSFP28 active optical cable designed for 100G Ethernet and InfiniBand environments. It delivers a pre-terminated, low-latency 100G link between QSFP28 ports without requiring separate optical transceivers, simplifying deployment in data center and high-performance network infrastructures. The cable supports direct connections between switches, servers and network devices where QSFP28 interfaces are available, reducing cabling complexity and improving airflow in racks.

Advantages

This active optical cable provides an integrated, plug-and-play solution for 100G links, eliminating the need for separate transceiver modules and fiber patch cords. The QSFP28 AOC offers low insertion loss and reduced latency compared with multi-component connections, and the 20 m length enables flexible rack-to-rack and row-to-row connectivity. Because it is a factory-terminated assembly, installation time is reduced and signal integrity is preserved across the full channel.

Suitable for

• Data center uplinks and spine-leaf fabrics
• Switch-to-switch high-speed interconnects
• Server-to-switch direct links in dense server environments
• High-performance computing and InfiniBand clusters requiring 100G links

Key specifications

• Interface type: QSFP28 to QSFP28 active optical cable
• Data rate: 100 Gbps aggregated bandwidth
• Length: 20 meters
• Cable type: Active optical cable with factory-terminated connectors
• Latency: low-latency design suitable for high-performance networks
• Compatibility: designed for equipment with QSFP28 ports supporting 100G Ethernet or InfiniBand

How to use

Connect the QSFP28 connector on each end of the AOC to the QSFP28 ports on your networking devices while both devices are powered off or live according to device vendor guidance. Once seated, the cable is recognized as a direct 100G link and requires no separate configuration beyond standard port setup on connected switches or servers. Ensure connectors are oriented correctly and fully inserted until the latch engages, and avoid sharp bends near the connector to maintain optical performance.

Usage recommendations

For reliable operation, route the 20 m AOC to avoid tight bends and mechanical strain, maintain appropriate rack airflow, and follow equipment vendor compatibility lists for QSFP28 modules and ports. Verify link status and speed in your switch or host operating system after installation and monitor for any errors or thermal warnings during initial operation.
