InfiniBand cable CBO CBL-QSFP-40GE-PASS-5M-BL, QSFP to QSFP, passive, 5 m

InfiniBand cable CBO CBL-QSFP-40GE-PASS-5M-BL is a 5-meter passive QSFP-to-QSFP copper link engineered for short-reach, high-bandwidth interconnects. Designed for use with compatible QSFP ports on switches, network adapters and servers, this cable supports 40 Gigabit Ethernet and InfiniBand connections. Its passive construction provides a simple, low-power physical layer connection that reduces complexity in rack and data center topologies while delivering low latency and stable throughput for latency-sensitive applications.

Advantages

The passive QSFP-to-QSFP cable offers a cost-effective alternative to active optics for short distances, with no additional power or modules required. Its fixed 5 m length simplifies cable management within server racks and between adjacent equipment, and the direct copper link ensures predictable latency and consistent signal characteristics. The cable is compatible with standard QSFP interfaces and is intended to provide reliable physical connectivity for 40GE and InfiniBand interconnects.

Key specifications

How to use

Install the cable by aligning each QSFP connector with the QSFP port on the equipment and gently inserting until the connector latches. Ensure both ends are connected to compatible QSFP ports configured for 40GE or InfiniBand operation. Verify link status on the connected devices and confirm network configuration and speed settings match the intended 40 Gigabit or InfiniBand link. For safe handling, avoid excessive bending and maintain recommended bend radius for copper direct attach assemblies.

Recommendations

Use this 5 m passive QSFP cable for short, high-bandwidth connections within racks or between adjacent racks. Verify QSFP compatibility with your switches and adapters, and check device firmware or vendor compatibility lists if available before deployment. Avoid routing the cable near sources of mechanical stress or sharp edges and maintain proper airflow in the rack.
