Cabo DAC CBO QSFP para QSFP cabo de cobre passivo 1 m (AT-QSFP1CU)

Direct Attach Copper (DAC) cable CBO QSFP to QSFP Passive Copper 1 m (AT-QSFP1CU) is a 1-metre passive QSFP-to-QSFP copper connection engineered for short-range, high-speed links between compatible network devices. The cable supports low-latency data transmission and reduces power consumption compared with optical transceivers, making it suitable for dense rack-to-rack and intra-rack interconnects in data centres and networking closets.

Advantages

The passive copper design offers a cost-effective, low-power interconnect option that eliminates the need for separate transceivers and optical modules. With a fixed 1 m length and QSFP-to-QSFP connectors, the cable provides a compact, easy-to-install solution that minimizes component count and simplifies cabling management. Its direct-attach architecture delivers predictable electrical performance and low latency for short-reach applications.

Key specifications

How to use

Confirm that both devices support passive QSFP-to-QSFP direct attach copper connections and that the QSFP ports accept passive cables. Insert each QSFP connector securely into the corresponding port until the latch engages. Avoid excessive bending of the cable and ensure proper airflow and cable routing in the rack to prevent mechanical stress. For removal, depress the connector latch and pull straight out, supporting the connector body rather than pulling on the cable jacket.

Recommendations

Use this 1 m passive QSFP DAC for short-distance interconnects where low latency and reduced power draw are priorities; verify device compatibility and supported data rates before deployment to ensure reliable operation.
