CBO InfiniBand cable QSFP-H40G-CU1M-HU-BL — QSFP to QSFP, 1 m, passive copper

CBO InfiniBand cable QSFP-H40G-CU1M-HU-BL is a 1-meter passive copper direct-attach cable with QSFP connectors on both ends. It is designed for short-reach, high-speed connections between switches, servers and storage devices that support QSFP, HDR or 40G interfaces. The cable provides a low-latency, point-to-point link suitable for rack- and chassis-level interconnects in data center environments where reliable, electrically connected links are required.

Advantages

The passive copper construction delivers consistent signal integrity for short distances while eliminating the need for separate transceivers, reducing system complexity and power consumption. QSFP-to-QSFP termination ensures direct compatibility with equipment that accepts QSFP modules, enabling simple plug-and-play deployment. The one-meter length balances flexibility and cable management in dense rack installations, and the robust connector housings are engineered for repeated insertion and removal.

Key specifications

How to use

Insert each QSFP connector into the corresponding QSFP port on the network devices, ensuring the latch engages and the connector is fully seated. Verify link status via the equipment LEDs or management interface after installation. For hot-pluggable environments, follow the host system guidance for safe insertion and removal to avoid port damage; power-down is generally not required for supported hardware but consult device documentation if uncertain. Route the cable to avoid tight bends and mechanical strain on the connectors.

Recommendations

For reliable operation, use this 1 m passive QSFP copper cable within the same rack or adjacent racks where short-reach electrical connections are appropriate. Avoid routing near strong electromagnetic interference sources and maintain bend radius recommended by the vendor. If longer distances or optical isolation are needed, consider active cables or fiber-optic transceiver solutions compatible with QSFP interfaces.
