InfiniBand active optical cable CBO QSFP-AOC-5M-DL-BO, QSFP to QSFP, 5 m

CBO InfiniBand active optical cable QSFP-AOC-5M-DL-BO is a 5 m QSFP-to-QSFP direct-link cable engineered for short-range, high-throughput interconnects. As an active optical cable, it converts electrical signals to optical and back within the cable assembly to provide low-latency data transmission and galvanic isolation between connected devices. The cable is intended for use in dense networking environments such as data centers and high-performance computing clusters where reliable, plug-and-play fiber connections between switches, routers and compute nodes are required.

Advantages

The active optical design reduces signal loss and enables longer reach compared with passive copper direct-attach solutions while maintaining low latency and high bandwidth. Integrated optics and transceiver electronics within the cable eliminate the need for separate transceiver modules, simplifying installation and reducing space and power consumption in rack deployments. The QSFP form-factor connectors support standard QSFP ports and ensure compatibility with network equipment that accepts QSFP-to-QSFP direct links.

Suitable for

• Short-reach interconnects between QSFP-capable switches and routers
• Server-to-switch or server-to-server connections in HPC clusters
• Top-of-rack and leaf-spine fabric links in data center racks
• Low-latency InfiniBand and RDMA deployments

Key specifications

• Cable type: active optical cable (AOC)
• Connector type: QSFP to QSFP
• Length: 5 meters
• Transmission: optical with integrated electrical-to-optical conversion
• Latency: low-latency design suitable for RDMA and InfiniBand traffic
• Compatibility: fits standard QSFP ports on networking and compute equipment

How to use

Install the cable by inserting each QSFP connector into the corresponding QSFP port on your devices until the latch clicks into place. No additional transceiver modules or optical patching are required. After physical connection, verify link status through the equipment management interface or LEDs on the ports. For hot-pluggable systems, the cable can be connected or removed while devices are powered on, but follow your equipment vendor guidelines for hot-swap procedures to avoid transient link errors.

Usage recommendations

Route the cable to avoid tight bends and mechanical strain; maintain the manufacturer-specified minimum bend radius for active optical assemblies. Use this 5 m QSFP-to-QSFP AOC for short-range links within racks or between adjacent racks and verify firmware and port compatibility with vendor documentation to ensure full functionality in InfiniBand or RDMA environments.
