Almost all sfp and sfp+ transceivers are multirate, but they vary quite a
lot.  For SFPs, some will do 100M, and many will handle up to 2.5G.  For
SFP+, some of them will handle 4G FC, almost all of them will handle both
8G FC and 10G ethernet, and many of them will handle rates greater than 10G
for stuff like SDH.  Some will also do 1G.

The OP needs to get transceivers will are coded to cisco specs.  There are
a couple of third party suppliers who will do this and who will provide
ongoing support for this.
