QSFP-4SFP10G-CU5M — QSFP+ 40 Gbps

The QSFP-4SFP10G-CU5M from Cisco is the longest DAC (Direct Attach Copper) cable in the QSFP+ breakout series, with 5 metres of passive copper extending 40 Gbps across four independent SFP+ 10 Gbps links. It operates without external power or optical modules, within a thermal range of 0 to 70°C.

This 5 m length is the recommended reference for connections between racks separated by two to three bays, in Cisco environments where an optical budget cannot be economically justified. The QSFP-4SFP10G-CU5M is the longest version in the Cisco copper breakout range and should be selected when the 1 m, 2 m, or 3 m variants do not cover the required distance.
