DAC cable CBO AT-QSFP-4SFP10G-1CU 10G QSFP to 4× SFP+ direct-attach copper, 1m, blue

The DAC cable CBO AT-QSFP-4SFP10G-1CU 10G QSFP to 4× SFP+ direct-attach copper, 1m, blue is a passive breakout cable that converts a single QSFP port into four independent 10 Gbps SFP+ links. Intended for short-reach interconnects in data center and telecom rack environments, this 1 metre copper assembly supports high-density port consolidation while maintaining low latency and reduced power consumption compared with active optical solutions. The cable is color-coded blue for easy identification and designed to fit QSFP and SFP+ transceiver sockets used in switches, servers and blades.

Advantages

This DAC cable offers four separate 10 Gbps lanes from a single QSFP interface, providing a compact and cost-effective solution for high-density deployments. As a passive copper direct-attach option it delivers low latency, negligible power draw and simple plug-and-play installation without the need for optical modules or separate power sources. The 1 m length is suitable for typical rack and top-of-rack interconnections and the robust connectors ensure reliable mating cycles and stable signal integrity for short-distance links.

Key specifications

How to use

Power off or follow hot-plug guidance for your network devices, then insert the QSFP end into the host QSFP port and plug each SFP+ connector into the target SFP+ ports. Confirm link negotiation and speed settings on the connected equipment and adjust firmware or interface settings if required by your switch or server platform. For reliable operation use the cable within its intended 1 m short-reach range and ensure connectors are free from debris before insertion.

Recommendations

Use this passive DAC for short-distance, high-density connections inside racks or between adjacent racks. Avoid exceeding the recommended reach and do not bend the cable sharply near the connectors. Check compatibility notes for your network hardware and update device firmware if necessary to ensure full 10 Gbps operation on all lanes.
