Cisco SFP-H25G-CU2M= 25GBASE-CU SFP28 Cable 2 m | DAC, 25 GbE — SFP-H25G-CU2M=

Maintain clean, short-reach 25 GbE connectivity with Cisco’s 2 m SFP28 copper direct attach cable. This twinax-style DAC is designed for links where optical modules are unnecessary and where cost, latency, and rack density all matter. By connecting SFP28 ports directly, it removes the need for separate transceivers and fiber patching, helping streamline deployment in tightly packed network environments. At 2 meters, this cable is well suited for adjacent rack and same-rack connections between switches, top-of-rack gear, and servers equipped with 25 GbE SFP28 interfaces. The direct attach design supports a cleaner physical layer with fewer components to manage, which can reduce points of failure and simplify day-two operations. For infrastructure teams standardizing on 25 GbE, it offers a practical way to keep short links efficient without overbuilding the connection path. Cisco cabling is often chosen where consistency matters as much as performance. This model fits environments that need dependable copper interconnects for high-throughput workloads, dense switching fabrics, and server aggregation layers. It is a straightforward choice when you want the economics of copper and the operational simplicity of a purpose-built DAC for short distances.
