InfiniBand cable CBO LSWM1QSTK1-BL 3 m QSFP passive copper

CBO LSWM1QSTK1-BL is a 3 m InfiniBand QSFP passive copper cable engineered for short-reach, high-throughput interconnects in data center and high performance computing environments. The cable features QSFP terminations on both ends and a fixed 3-metre length to link switches, servers and storage with minimal latency and low power consumption compared with active or optical alternatives.

Advantages

This passive copper QSFP cable delivers consistent low-latency transmission and stable electrical performance for short-distance connections. It eliminates the need for optical modules for short links, reducing component count and overall system cost. The direct-attach design is plug-and-play, requires no external power or configuration, and provides predictable signal integrity suitable for dense rack deployments.

Key specifications

How to use

Insert each QSFP connector into the appropriate QSFP port on your switches, servers or storage devices until the latch engages. Confirm link status through device indicators or management interfaces and verify negotiated link speed. For best results, route the cable to avoid sharp bends and mechanical strain; maintain recommended bend radius and secure the cable to prevent movement in dense cabling environments.

Recommendations

Use this 3 m passive QSFP copper cable for short, high-bandwidth links inside racks or between adjacent racks. Avoid extended routing through cable trays or near high-EMI sources. Inspect connectors for debris before insertion and ensure QSFP ports support passive copper direct-attach connections and the intended InfiniBand speed.
