The Cisco SFP-H25G-CU2.5M is a 2.5-meter long twinax copper cable for high-speed data transmissions up to 25 Gbps. Featuring passive copper technology, this direct attach cable provides reliable and efficient connectivity between devices equipped with SFP28 connectors.

With connectors on both ends being the same type (SFP28), it ensures compatibility across various network equipment such as switches, routers, servers, and storage devices that support these interfaces.

Copper cables are known for their cost-effectiveness compared to fiber optic alternatives while still delivering excellent performance over short distances like in data centers or server rooms where they are typically used.

Measuring at only 2.5 meters, this cable maintains optimum signal integrity due to its low attenuation characteristics provided by the robust construction of twisted-pair cabling.
