Q&A

How long is the Cisco SFP-H25G-CU4M?

The Cisco SFP-H25G-CU4M is a 25G SFP28 direct-attach copper cable measuring 4 m. Because the modules are factory-terminated at both ends, the cable cannot be shortened or re-terminated in the field — order the exact length required.

Is the Cisco SFP-H25G-CU4M copper or optical?

It is a direct-attach copper cable (Passive copper (twinax)): Passive, no external power, terminated with SFP28 to SFP28 connectors. It carries the link without separate transceivers at each end.

How does the Cisco SFP-H25G-CU4M compare with the Cisco SFP-H25G-CU1M?

The SFP-H25G-CU4M reaches 4 m assembly length over Passive copper (twinax), while the SFP-H25G-CU1M reaches 1 m assembly length over Passive copper (twinax). Pick the shortest reach that covers the link distance — going longer than needed costs more and adds optical budget margin you will not use.
