Cisco Systems, Inc. SFP-H25G-CU2M= 25G SFP28 Passive Copper Cable 6.56 ft

25G SFP28 passive copper cable

This Cisco SFP28 passive copper cable provides a direct 25 Gigabit Ethernet link between two SFP28 ports. It is built for data-centre and high-performance computing environments that need low-power, high-density connectivity without active optics. The 6.56 ft length suits rack-to-rack or intra-rack runs where a fixed copper assembly is preferred.

Fits SFP28 slots with no external power

Each end terminates in an SFP28 male connector that plugs directly into a compatible switch, router or NIC port. Because the assembly is passive it draws no additional power from the host system and requires no separate transceiver module. The fixed cable eliminates the need to stock or manage separate patch cords and optical transceivers for short-reach links.

Passive design maintains signal integrity over

The copper construction delivers consistent 25 Gb/s throughput across the entire 6.56 ft run without the latency or power overhead of active equalisation. Heat output remains negligible, helping preserve thermal headroom in dense chassis. The cable is intended for sustained 25G operation in controlled environments where bend radius and cable management follow standard installation practices.
