Re: 25G SFP28 capable of rate-adaption down to 1G?

Are you talking about an SFP28 module that can link at 25Gb, but also 1Gb? We just put 1Gb SFPs in the SFP28 ports and they work fine. I have not seen a single module that does both, but admittedly, I have not looked too hard, as the 1Gb modules are so cheap. Or, are you talking about a module that presents as 25Gb to the switch, but 1Gb to the client device? thanks, -Randy ----- On Jan 31, 2022, at 1:05 PM, Bill Woodcock woody@pch.net wrote:

Hey, does anyone know of an SFP28 capable of rate-adapting down from 25G on the cage side down to 1G on the line side? Can be copper or fiber on the line side, I don’t care, my interest is in the chip inside.

Thanks,
