BlueOptics QSFP-H40G-AOC3M-HU-BO InfiniBand fibre optic cable 3 m Male/Male

The BlueOptics QSFP-H40G-AOC3M-HU-BO InfiniBand fibre optic cable 3 m Male/Male is a 3-meter active optical cable (AOC) with QSFP-to-QSFP connectors designed for short-reach, high-speed links. It implements a 40GBASE-SR4 compatible electrical and optical interface using multimode fibre with an integrated transmitter and receiver on each end. The cable is intended for direct interconnection of switches, routers, storage systems and other network devices that accept QSFP 40G AOC modules and supports industry-standard InfiniBand and Ethernet signalling at up to 40 Gbit/s over the 3 m span.

Advantages

This BlueOptics active optical cable delivers a compact, lightweight connection that reduces electromagnetic interference and eliminates the need for separate transceivers or patch panels for short-reach links. Compliance with QSFP form-factor and 40GBASE-SR4 compatible signalling ensures interoperability with devices that support standard QSFP AOC modules. Built-in optical transceivers on both ends provide consistent optical performance for high-throughput applications while the 3 m length helps maintain signal integrity in dense rack and cabinet environments.

Key specifications

How to use

Install by inserting each QSFP connector into the corresponding QSFP port on the network devices until the latch engages. Ensure both ends are seated and that connected devices are configured for 40G operation or the appropriate InfiniBand/Ethernet protocol. No separate optical transceivers or patch cables are required; treat the cable as a single integrated link. Avoid sharp bends, excessive pulling force and contact with active metal edges during installation to protect the fibre and connector ferrules.

Recommendations

For reliable operation, use the cable for short-reach connections up to 3 m inside racks and between adjacent cabinets, verify device compatibility with QSFP 40G AOC modules, and keep connector endfaces clean. Store and route the cable following standard fibre handling practices to maintain performance.
