Can 25GbE sfp operate on 10Gb ?

[AlexeyF]

Hi

I wonder if 25GbE SFP28 ports can operate on 10Gb ?

we have X65404 model transceivers 

are there any limitations ?

Thanks

Unfortunately not - optical ethernet transceivers are always single rate. Please contact your account team to obtain pricing for appropriate transceivers.

No, a 25gbit SFP is 25gbit only.

Do these ports support RS-FEC ?
