CBO InfiniBand cable BN-QS-QS-CBL-1M-BL — 1 m QSFP to QSFP, blue jacket

Direct-attach CBO InfiniBand cable BN-QS-QS-CBL-1M-BL is a 1 metre QSFP-to-QSFP link with a blue jacket designed for short-range high-speed interconnects. It provides a fixed-length QSFP connection without the need for separate transceivers, suitable for direct connections between QSFP ports in servers, switches and storage systems. The cable's compact construction and 1 m length make it practical for within-rack or adjacent-rack connections where low latency and high throughput are required.

Advantages

This QSFP-to-QSFP cable reduces component count by eliminating external transceivers and associated power and cooling overhead. The fixed 1 m length simplifies cable management in dense rack environments, while the blue jacket aids visual identification and organisation. Designed for InfiniBand signalling, it supports high data rates over a short distance with low latency and reliable physical connectivity.

How to use

Ensure both ports are QSFP-compatible and powered off or in a hot-pluggable state according to your equipment's guidelines. Align the QSFP connectors with the device ports and insert firmly until the latch engages. Verify link status through the host system or switch management interface and confirm expected data rates and link stability. For removal, release the connector latch and pull straight out to avoid damaging the port or cable.

Recommendations

Route the cable to avoid sharp bends and maintain the manufacturer's minimum bend radius. Use in environments where the 1 m length provides the required reach; for longer distances select an appropriate alternative. Keep the cable free from excessive tension and away from hot components to preserve signal integrity and mechanical reliability.
