InfiniBand/fibre optic cable BlueOptics QSFP-40G-D-AOC-20M-H-BO 20m Male/Male

The BlueOptics QSFP-40G-D-AOC-20M-H-BO is a 20-metre active optical cable designed for high-speed InfiniBand and fibre channel environments. With QSFP connectors on both ends and a male-to-male configuration, this cable supports 40Gbps data rates and is intended for short to medium reach interconnects in data centres, server racks and high-performance networking equipment.

Advantages

The cable combines the compact QSFP form factor with optical transmission to reduce electromagnetic interference and heat compared with copper alternatives. Its 20 m length provides flexibility for connecting switches, servers and storage arrays across racks without additional transceivers. The pre-terminated active optical design simplifies installation and reduces the number of active components required in each enclosure.

How to use

Ensure both network ports support QSFP 40Gbps interfaces and are powered off or in a state that allows hot-plugging according to the equipment manual. Align the QSFP connector keying with the port and insert the cable until the latch engages. Verify link status on connected devices and check for expected data rates in the host or switch management interface. If the devices provide diagnostics, confirm optical parameters such as link up and signal levels. When removing the cable, release the connector latch and pull straight out to avoid damaging the port.

Recommendations

Use the cable in temperature-controlled rack environments and avoid tight bends or kinks that could stress the optical fibres. For critical links, verify compatibility with the network equipment vendor's QSFP specifications and test the link after installation. Store unused cables coiled loosely and protected from dust and mechanical stress.
