CVR-QSFP28-SFP25G for 9500-32C to 25G SFP ?

[pwwiddicombe]

I have a need to be able to connect 25G fiber from a 9500-48y4c, to C9500-32C's.   Will the CVR-QSFP28-SFP25G allow me to use the 10/25G SFP's; or is there an alternative to permit that?

Should work just fine, as both switches support that QSFP. See table-2 in this link:

That's the problem, actually. QSFP-4SFP25G as a breakout cable is supported for 25G copper within a few feet - but not fiber; and not as a converter for higher than 10G.

How about this:

I am just not sure if these switches support it.

Cisco actually has one of their own (plus there are some available from third parties); unfortunately there seems to be no documentation from Cisco as to what Cisco plafforms it's compatible with ?
