BlueOptics InfiniBand Fibre Optic Cable 20m QSFP Male-Male

The BlueOptics InfiniBand Fibre Optic Cable 20m QSFP Male-Male is an active optical cable (AOC) designed for 40G data transmission over multi-mode fiber. With QSFP-to-QSFP connectors and a 20-metre length, this cable integrates transceivers and optical components in a pre-assembled solution that supports high-throughput links between switches, routers, storage systems and other compatible network devices. The cable follows MSA QSFP form-factor conventions and offers a factory-tested replacement option for platforms that accept comparable 40GBASE-SR4 AOCs.

Advantages

This BlueOptics 20m QSFP AOC provides optical data transmission that is immune to electromagnetic interference and reduces signal attenuation compared with copper alternatives. Built with high-quality laser diodes and integrated circuits sourced from established component manufacturers, the cable includes transceivers on both ends and supports simultaneous send/receive operation. It offers digital diagnostics (DDM/DOM) for real-time monitoring of voltage, laser bias current, output power, received power and temperature when supported by the host hardware. Factory testing against major hardware platforms ensures functional compatibility and long-term reliability.

Suitable for

• High-performance computing clusters and InfiniBand fabrics
• Data-centre switch-to-switch or switch-to-server connections
• Storage area network (SAN) links and server interconnects
• Low-latency networking for virtualization and HPC applications

• Length: 20 metres
• Data rate: up to 40 Gbit/s (40GBASE-SR4 compatible)
• Fiber type: multi-mode fiber (integrated within AOC)
• Active components: integrated transmitter and receiver at each end
• Monitoring: Digital Diagnostics Monitoring / Digital Optical Monitoring (DDM/DOM) support
• Form factor: QSFP MSA compliant

How to use

Install the BlueOptics 20m QSFP AOC by inserting the QSFP connectors into compatible QSFP ports on your network devices until the latch engages. Ensure the host devices support 40GBASE-SR4/InfiniBand AOC modules and, if you intend to use DDM/DOM monitoring, verify that the hardware and firmware expose diagnostic readouts. No field termination or patching is required because the cable is pre-assembled; avoid bending the cable beyond the recommended minimum bend radius and route it to prevent mechanical strain on the connectors.

Usage recommendations

For reliable operation, confirm compatibility with the target hardware platform and keep device firmware up to date. Avoid sharp bends and physical damage; maintain a clean environment around connector insertion points. If DDM/DOM data is required for diagnostics, enable the monitoring interface on the host device and observe the reported parameters during commissioning and routine checks.
