InfiniBand / fibre optic cable BlueOptics R5Z80A-BO, QSFP56 to QSFP56, 5 m, turquoise

BlueOptics R5Z80A-BO is a 5 m InfiniBand / fibre optic active optical cable (AOC) with QSFP56 connectors on both ends, designed for high-speed server, switch and storage interconnects in data centre and HPC environments. The cable supports 200GBASE-SR4 transmission over multimode fibre, provides simultaneous transmit and receive channels, and includes Digital Diagnostics Monitoring (DDM/DOM) for real-time status of voltage, laser current, optical power and temperature. The cable is lightweight (0.23 kg) and finished in turquoise for easy visual identification.

Advantages

The BlueOptics AOC follows MSA QSFP56 standards and is built from quality optical components to ensure compatibility with common hardware platforms that support QSFP56 200G AOC connections. Active optical design reduces electromagnetic interference and enables lower latency and higher bandwidth compared with copper solutions for similar distances. Integrated digital diagnostics simplify monitoring and remote troubleshooting while the compact, lightweight construction facilitates cable routing and installation in high-density racks.

How to use

Install the QSFP56 connectors into compatible QSFP56 ports on switches, routers, servers or storage devices while equipment is powered down or following the vendor’s hot-plug guidance. Ensure both endpoints support 200GBASE-SR4 and, if you need monitoring data, confirm the host devices support DDM/DOM to access diagnostic values. Route the cable in the rack with adequate bend radius and secure it to avoid strain on the connector housings. After insertion, verify link status and throughput on the connected devices according to their management interface.

Recommendations

Use this 5 m QSFP56 AOC for short-reach, high-bandwidth links inside data centre racks or between adjacent racks. Maintain the manufacturer’s minimum bend radius, keep connectors clean and capped when not in use, and verify DDM/DOM support on host equipment before relying on diagnostic metrics for monitoring.
