QSFP-4SFP25-CU5M — Cisco QSFP+

The QSFP-4SFP25-CU5M is a Cisco passive breakout direct attach cable in the QSFP+ form factor, fanning out to four SFP28 25G connectors. At 5 metres in length, it splits a single QSFP+ port into four independent 25G links for connecting multiple servers or devices from a single uplink port.

This 5 m length, the longest in the QSFP-4SFP25-CU series, is suited to deployments where equipment is spread over a greater distance — for example, across two rows of cabinets in a data center. It is distinguished from the CU4M, CU3M, CU2M, and CU1M variants by its extended reach. Genuine Cisco hardware, manufacturer warranty.
