QSFP-4SFP10G-CU3M — QSFP+ 40 Gbps

The QSFP-4SFP10G-CU3M from Cisco is a 3-metre QSFP+ passive copper breakout cable (DAC) enabling a 40 Gbps link to be distributed across four SFP+ 10 Gbps interfaces. With no active components, it delivers near-zero latency and minimal power draw, for operating temperatures between 0 and 70°C.

The 3 m reach of the QSFP-4SFP10G-CU3M covers close inter-bay cabling scenarios in a datacenter, notably links between a 40G aggregation switch and 10G servers spread across two adjacent racks. It sits between the 2 m and 5 m variants of the CU family, providing the right compromise for mid-range distances. Genuine Cisco hardware, manufacturer warranty.
