SFP-H25G-CU1M Description
The SFP-H25G-CU1M is a Cisco 25GBASE-CR1 SFP28 passive copper cable for direct 25 Gigabit Ethernet connections inside one rack. The 1-meter cable has SFP28 connectors at both ends, draws up to 0.1W and operates from 0 to 70 degrees C. The cable needs no host FEC at this length, so a port can run it without enabling BASE-R FEC or RS-FEC.

Application Scenarios
Inside one server cabinet, the cable joins a server SFP28 port to a 25G switch port a short run away, with passive copper and no optics at either end.
Catalyst 9200L fixed 25G uplink ports and the Catalyst 9300 25G uplink network module accept the cable for a one-meter connection to a neighboring switch in the same closet.

SFP-H25G-CU1M is a 1-meter passive copper SFP28 cable that needs no host FEC, as does SFP-H25G-CU2M, so a run that exceeds 1 meter but fits within 2 meters moves to SFP-H25G-CU2M. SFP-H25G-CU3M reaches 3 meters but requires BASE-R FEC on the host port, so the host must support that setting before it replaces either shorter cable. Where the same 1-meter run must be optical, SFP-25G-AOC1M matches the length but draws 1W against 0.1W and requires BASE-R FEC or RS-FEC on the host port.
Ordering Checklist
- C1300X hosts: Confirm the switch is a C1300X with SFP28 ports, such as C1300X-24T-4X, C1300X-48P-4X or C1300X-10NU-2X. The cable is listed for the C1300X SFP28 ports, where 25G is available for stacking only and uplinks run at 10G.
