CBO InfiniBand Cable DEM-CB100QXS-BL 1 m QSFP black

Passive InfiniBand cable DEM-CB100QXS-BL from BlueOptics is a 1 m direct-attach copper solution with QSFP connectors designed for short-range, high-speed interconnects. The cable supports connections between switches, host adapters and storage systems that use QSFP interfaces, offering a compact alternative to optical transceivers for rack-level links and dense data centre topologies. Its single‑meter length minimises excess cabling while maintaining the signal integrity required for low-latency environments.

Advantages

The cable provides a reliable, low-latency physical link suitable for short-range InfiniBand connections. As a passive QSFP direct-attach cable, it reduces the need for separate transceivers and fibres, simplifying installation and lowering component count. The compact 1 m form factor helps keep rack layouts tidy and reduces signal attenuation associated with longer runs. The black jacket offers standard colour coding and mechanical protection for frequent handling in data centre racks.

Key specifications

How to use

Connect one QSFP end into the QSFP port of a network switch, host adapter or storage unit and the other end into the corresponding QSFP port on the paired device. Ensure both devices are powered down or meet hot-plug guidelines recommended by the equipment manufacturer before insertion or removal. Route the cable to avoid tight bends and mechanical strain on the connectors; secure any excess length within the rack to maintain airflow and accessibility.

Recommendations

Use this 1 m passive QSFP cable for short, rack-level links where distance does not require active or optical cabling. Verify compatibility of QSFP port speeds and InfiniBand link settings on both devices before deployment and follow equipment vendor guidelines for hot‑plug operations and ESD protection.
