QSFP-4SFP25-CU4M — Cisco QSFP+

The QSFP-4SFP25-CU4M is a Cisco 4-metre passive breakout direct attach cable, with a QSFP+ connector on the aggregation side and four SFP28 25G ports on the server side. With no active components, it delivers minimal latency and reduced power consumption for high-density data center interconnections.

At 4 metres, this breakout DAC is suited to spanning the width of a standard cabinet row or connecting a mid-aisle top-of-rack switch. It is distinguished from the CU5M (5 m) by its slightly shorter length, offering greater flexibility in dense cabling environments. Genuine Cisco hardware, manufacturer warranty.
