BlueOptics ET7502-AOC-3M-BO InfiniBand fibre optic cable 3m QSFP-DD Male/Male

The BlueOptics ET7502-AOC-3M-BO InfiniBand fibre optic cable 3m QSFP-DD Male/Male is a 3‑meter active optical cable designed for high-density data center and high-performance computing environments. It features QSFP‑DD male connectors on both ends and uses multi‑mode fibre with integrated transmitter and receiver modules to carry optical signals for InfiniBand and compatible 400GBASE-SR8 or other high‑speed protocols where QSFP‑DD interfaces are supported.

Advantages

This QSFP‑DD AOC offers a compact, low-latency connection with consistent optical performance across its 3 m length. The integrated transceiver design eliminates separate SFP/QSFP modules, reducing component count and simplifying rack cabling. It is intended for direct-mate, high-throughput links between QSFP‑DD ports in switches, routers, storage systems and compute nodes that support QSFP‑DD AOC connectivity.

How to use

Install the cable by inserting each QSFP‑DD connector into the matching QSFP‑DD port on your devices until it latches. Ensure that connected devices are powered down or follow hot‑swap procedures recommended by the device vendor. Verify that your switches, routers or hosts support QSFP‑DD AOC modules and the intended protocol (InfiniBand, 400G Ethernet modes, etc.). After connection, confirm link status and speed via device management interfaces and monitor for any error counters during initial operation.

Recommendations

Use this 3 m QSFP‑DD AOC in short‑reach topologies such as within racks or between adjacent racks. Verify compatibility with your hardware vendor’s support list before deployment, handle connectors by the housing to avoid contamination, and keep dust caps on unused ports. For stable high‑speed operation, maintain bend radius limits for the cable and avoid excessive tension or tight cable management routing.
