BlueOptics QDD-400G-AOC-3M-BO InfiniBand fibre optic cable 3m QSFP-DD Male

The BlueOptics QDD-400G-AOC-3M-BO InfiniBand fibre optic cable 3m QSFP-DD Male is a 3‑meter active optical cable (AOC) with QSFP-DD male connectors at both ends, designed for high‑speed short‑reach links. It implements 400GBASE‑SR8 style transmission over multimode fiber with integrated transmitter and receiver modules on each connector, providing a factory‑terminated, low‑latency connection for switches, routers and compute or storage nodes that accept QSFP‑DD interfaces.

Advantages

This QSFP‑DD AOC delivers a compact, pre‑tested connection that removes the need for separate transceivers and fiber patching, reducing installation time and potential connection errors. With support for 400 Gbit/s aggregate throughput over a 3 m link and multimode optics, the cable offers consistent signal integrity and predictable performance in data center topologies. The male‑to‑male QSFP‑DD configuration simplifies direct device‑to‑device links and is compatible with equipment that supports QSFP‑DD AOC modules.

How to use

Install the BlueOptics QSFP‑DD AOC by aligning and inserting each QSFP‑DD male connector into the QSFP‑DD cages on the devices until the retention mechanism engages. Ensure both endpoints are powered and that device firmware or hardware supports QSFP‑DD AOC modules and the intended 400G protocols. No additional transceivers or optical patch cords are required; the cable is ready for operation once seated and recognized by the equipment. For moves or replacements, remove the cable by releasing the connector latch and withdrawing straight out to avoid stressing the cable assembly.

Recommendations

Place and route the cable to avoid tight bends and mechanical strain, keeping bend radius within manufacturer guidance for multimode AOC assemblies. Verify device compatibility with QSFP‑DD AOC modules and confirm link settings (protocol, speed, lanes) in the equipment management interface after installation. In high‑density rack environments, plan cable routing to maintain airflow and allow access for service.
