InfiniBand/fibre optic cable BlueOptics 740-060378-BO 10 m QSFP Male/Male

The BlueOptics 740-060378-BO is a 10 m active optical cable (AOC) with QSFP male-to-male connectors designed for high-speed InfiniBand and multimode fibre applications. It supports 40GBASE-SR4 class transmission and is intended for direct QSFP-to-QSFP connections in switches, routers and storage systems that accept QSFP 40G AOCs. The cable integrates optical transmitters and receivers on each end to enable simultaneous send/receive operation over multimode fibre and is manufactured to MSA-compliant form-factor and signaling requirements for interoperability with compatible hardware.

Advantages

The 10 m BlueOptics QSFP AOC provides high-bandwidth, low-latency connectivity without susceptibility to electromagnetic interference, as optical transmission avoids EMI. Pre-terminated QSFP-to-QSFP construction eliminates the need for separate transceivers, patching or manual fibre termination and reduces insertion loss from patch cords. Built and tested to MSA standards, the cable includes digital diagnostics (DDM/DOM) support for real-time monitoring of operating parameters where supported by host hardware. The manufacturing approach emphasizes component quality and aims for long operational lifetime and high availability in data centre environments.

Suitable for

• 40 Gbps short-reach server-to-switch or switch-to-switch links
• High-throughput storage connectivity and SAN interconnects
• Low-latency cluster interconnects and HPC/InfiniBand fabrics
• Data centre rack-to-rack optical links where QSFP-to-QSFP AOC is supported

Key specifications

• Cable type: Active Optical Cable (AOC), pre-terminated QSFP-to-QSFP
• Length: 10 meters
• Connector: QSFP male on both ends (QSFP-to-QSFP)
• Maximum data rate class: 40G (40GBASE-SR4 equivalent multimode operation)
• Medium: Multimode fibre with integrated optical transceivers
• Monitoring: Digital Diagnostic Monitoring / Digital Optical Monitoring (DDM/DOM) capable when supported by host

How to use

Install the BlueOptics QSFP AOC by inserting each QSFP connector into the corresponding QSFP port on compatible network devices, ensuring proper alignment and latch engagement. Confirm that the host devices support QSFP 40G AOC modules and, if required, enable or verify DDM/DOM support in device firmware or management interfaces to access diagnostic data. No fibre polishing or patching is required; handle connectors by the housing to avoid touching optical interfaces and avoid tight bends along the cable length to preserve optical performance.

Recommendations

Use in network equipment that explicitly supports QSFP 40G AOCs and ensure firmware compatibility; avoid sharp bends and maintain recommended bend radius. If monitoring is needed, verify that the connected devices expose DDM/DOM parameters to the management system.
