## Summary description

Direct Attach Copper (DAC) cable CBO AT-QSFP1CU is a 1 meter passive QSFP-to-QSFP copper connection designed for short-range high-speed links between compatible network devices. It provides a low-latency, energy-efficient alternative to optical transceivers for rack-to-rack or intra-rack interconnects, simplifying installation and reducing component count.

## Long description

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.
Suitable for
Rack-to-rack and intra-rack high-speed connections in data centres
Switch-to-switch and server-to-switch links with compatible QSFP ports
Short-reach 40/56/100 Gbps interconnects where passive copper is supported
Key specifications
Cable type: passive copper Direct Attach Cable (DAC)
Connector type: QSFP to QSFP
Length: 1 metre
Use case: short-reach high-speed interconnects
Performance: low-latency, energy-efficient electrical link for compatible QSFP ports
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.
Usage 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.
