CBO InfiniBand QSFP to QSFP Cable CAB-Q-Q-5M-BL — 5 m, black

The CBO InfiniBand QSFP to QSFP Cable CAB-Q-Q-5M-BL is a 5 m black direct-attach cable designed for QSFP ports in servers, switches and storage equipment. Intended for InfiniBand interconnects, this fixed-length cable offers a single-cable solution for short to mid-range intra-rack connections where a reliable, low-latency link is required. Its compact, pre-terminated design simplifies installation in dense rack environments and avoids the need for separate transceivers.

Advantages

This QSFP to QSFP cable provides a predictable physical connection with consistent signal performance and low insertion loss. The 5 m length balances flexibility and manageability for typical rack and row layouts, while the robust black jacket protects the internal conductors from physical wear. As a passive direct-attach solution for InfiniBand links, it reduces component count and can lower overall system power compared with active transceiver-based alternatives.

How to use

Align each QSFP connector with the corresponding port on your network device and insert until the latch engages. Ensure both devices are powered and configured for the same InfiniBand link parameters prior to data transmission. Route the cable to avoid sharp bends and excessive tension; maintain appropriate bend radius as recommended for QSFP assemblies. For dense installations, label both ends to simplify identification and troubleshooting.

Recommendations

Use this fixed-length QSFP to QSFP cable for short- to mid-range intra-rack connections where direct, low-latency links are required. Avoid installation in routing paths exposed to mechanical strain or temperatures outside typical data center operating ranges. Periodically inspect connectors for dirt or damage and clean with appropriate tools if necessary.
