"show int" will give some limited information:

switch#show int g0/25
GigabitEthernet0/25 is up, line protocol is up (connected)
[..]
  Full-duplex, 1000Mb/s, link type is force-up, media type is 1000BaseSX SFP

or:

GigabitEthernet0/28 is up, line protocol is up (connected)
[..]
  Full-duplex, 1000Mb/s, link type is auto, media type is 1000BaseLX SFP

if the transceiver implements the features, you can add "transceiver"
option to above command to get additional monitoring information ...
