BlueOptics QDD-400-AOC3M-BO InfiniBand fibre optic cable 3 m QSFP-DD

The BlueOptics QDD-400-AOC3M-BO InfiniBand fibre optic cable 3 m QSFP-DD is a 3-metre active optical cable with QSFP-DD male connectors on both ends, designed for high-speed data transmission in data centers and networking environments. Built to support 400G applications over multimode fibre, this AOC integrates transmitter and receiver components to transfer optical signals with low latency and reliable performance. The cable conforms to QSFP-DD form factor and MSA-compatible specifications, making it suitable for direct connections between switches, servers and storage hardware that accept QSFP-DD modules.

Advantages

This 3 m active optical cable provides high-density, high-throughput connectivity without the need for separate transceiver modules, reducing rack space and simplifying cabling in dense environments. Being an active optical cable, it delivers electrical-to-optical conversion within the connector housings which enables longer reach and lower signal loss over multimode fibre compared with passive copper alternatives. The QSFP-DD to QSFP-DD interface supports multi-lane 400G operation suitable for Ethernet, Fibre Channel over Ethernet or SDH/SONET compatible workflows, while maintaining compatibility with major networking platforms that accept QSFP-DD AOCs.

How to use

Install the BlueOptics QDD-400-AOC3M-BO by inserting each QSFP-DD connector into the corresponding QSFP-DD port on the networking equipment until it latches. Ensure both endpoints support QSFP-DD AOC connections and the intended 400G or multi-lane configuration. No separate transceivers or external power supplies are required beyond the host ports. Verify link negotiation and configuration in the device management interface and confirm the expected protocol (Ethernet, Fibre Channel over Ethernet or SDH/SONET) and speed settings. Handle the cable by the connector housings and avoid tight bends to maintain fibre integrity.

Recommendations

For optimal performance, use the cable within recommended bend radius limits, keep connectors clean and protected when not connected, and verify compatibility with your hardware platform's supported QSFP-DD AOC devices. Consider testing a sample in your specific setup to confirm interoperability and link behavior under your workload.
