InfiniBand/fibre optic cable Cisco QSFP-100G-AOC3M= 3 m

The Cisco QSFP-100G-AOC3M= is a 3 m active optical cable with QSFP connectors on both ends, designed for short-distance, high-speed links in data centers and HPC environments. It supports 100G Ethernet and InfiniBand applications, delivering low latency and reliable performance while being thinner and lighter than equivalent copper cables.

Advantages

Active optical construction reduces cable weight and diameter compared with copper, improving cable management and enabling better airflow in high-density racks. The QSFP-to-QSFP design ensures straightforward compatibility with equipment that accepts QSFP 100G ports and provides consistent signal quality for short-reach connections.

Suitable for

• Connecting switches, servers and storage within the same rack
• Inter-rack links in data centres over short distances (up to 3 m)
• High-performance computing (HPC) clusters and InfiniBand fabric links

How to use

Plug each QSFP connector into compatible QSFP ports on network devices or adapters. Ensure both endpoints support 100G QSFP connections and that devices are powered and configured for the intended link speed and protocol. Route the cable to avoid sharp bends and mechanical stress; the thin, flexible construction simplifies routing in dense rack environments.

Recommendations

Use the cable for short-reach connections within racks or between adjacent racks. Maintain bend radius and avoid excessive tensile force. Verify device compatibility with QSFP 100G ports and confirm firmware or driver settings for optimal operation.
