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

The BlueOptics AOC-Q-Q-40G-20M-CT-BO is a 20-metre active optical cable (AOC) with QSFP male connectors on both ends, designed for InfiniBand and 40GBASE-SR4 applications. This pre-assembled multimode fibre solution integrates optical transmitters and receivers at each end to deliver up to 40 Gbit/s over a 20 m link, offering a tested, plug-and-play connection for data centre switches, routers and storage systems that support QSFP to QSFP links.

Advantages

This active optical cable provides high-bandwidth, low-latency data transmission without susceptibility to electromagnetic interference. It conforms to MSA standards for QSFP-to-QSFP AOCs and includes Digital Diagnostics Monitoring (DDM/DOM) for real-time monitoring of supply voltage, laser bias current, output and received power, and temperature. The cable is assembled using high-quality optical components and is designed for long service life and reliable performance in professional networking environments.

Key specifications

How to use

Install the BlueOptics AOC-Q-Q-40G-20M-CT-BO by inserting the QSFP male connectors into QSFP ports on supporting devices. Ensure both host ports support QSFP AOC modules and the required 40GBASE-SR4 or InfiniBand protocol. No additional transceivers or patching are required; power and signalling are provided by the connected devices. If device firmware or vendor compatibility lists are used, verify support for third-party AOCs where required by the hardware vendor.

Recommendations

Verify that target hardware supports QSFP AOCs and DDM/DOM if you intend to use digital diagnostics. Route the cable to avoid sharp bends and mechanical stress, maintain multimode fibre bend-radius guidelines, and keep connectors clean during installation. Use the BlueOptics AOC for short-reach, high-bandwidth links in controlled data-centre environments.
