QSFP-4SFP10G-CU4M — QSFP+ 40 Gbps

The Cisco QSFP-4SFP10G-CU4M is a passive QSFP+-to-4xSFP+ breakout DAC cable delivering 40 Gbps across four 10 Gbps lanes over a length of 4 metres of pre-terminated copper. With no active components, it minimises power consumption and latency, with an operating range of 0 to 70 °C.

With its 4 m of copper, this breakout DAC cable suits connections between a QSFP+ 40G switch and four SFP+ 10G devices located a few rack units away, where a 3 m cable would fall short. It is a cost-effective solution for rapidly deploying 10G fanout links in server rooms. Genuine Cisco hardware, manufacturer warranty.
