QSFP-4SFP10G-CU1M — QSFP+ 40 Gbps

The QSFP-4SFP10G-CU1M from Cisco is a QSFP+ breakout DAC (Direct Attach Copper) cable providing 40 Gbps connectivity to four SFP+ 10 Gbps ports over a length of one metre. This passive pre-terminated copper cable operates between 0 and 70°C and requires no optical module, simplifying management and reducing port power consumption.

At 1 m of reach, the QSFP-4SFP10G-CU1M is the shortest copper breakout solution in the Cisco range, ideal for intra-rack connections between a 40G switch and 10G ToR (Top-of-Rack) switches in the same bay. It differs from the CU2M, CU3M, and CU5M variants solely by its minimum length. Genuine Cisco hardware, manufacturer warranty.
