SFP-H25G-CU1 — Cisco SFP28 25G

The SFP-H25G-CU1 is a Cisco passive direct attach cable in the SFP28 25G form factor, measuring 1 metre in length. With no active components, it provides a direct 25 Gigabit Ethernet link between two SFP28-compatible devices with near-zero power draw and negligible latency.

This 1 m length makes it the preferred solution for intra-cabinet connections, particularly between a server and a top-of-rack switch installed in the same rack. Compared to the SFP-H25G-CU2 (2 m), it is optimised for very compact installations where every centimetre of cabling matters. Genuine Cisco hardware, manufacturer warranty.
