We haven't had any problems with plugging FDR stuff into and EDR
switch. It does downgrade the connections but still works.

Heya,
I do very much the same QSFP28-EDR 100G adapter cards into QSFP+-FDR
56G just with the use of a cable. I even QSFP+-FDR to 4x SFP+-10G
using various brocade, mellanox, chelsio hardware and have never come
out worse.
Some cables can be a bit funny but I have never had issues with cables
branded by NetApp, DELL, CISCO or purchasing coded variants from
suppliers. However FS.com are a valued cable supplier for anything
that I might think could be a bit fickle.
Allot of the time it is cable compatibility and rarely the adapters
themselves.
Hope this help you out buddy :)
Kind regards,
Darren Wise

has anyone plugged a mellanox fdr card into a mellanox edr switch? i
need to connect a server that doesn't have a x16 port so no edr card,
but i do have an fdr card that's x8. i don't need the speed just the
connection, but i've not tried this before. a quick google says it
should work, but i'm loathe to until i hear someone else has.
