You will need the part number to determine SFP compatibility. This is from Digital Optical Monitoring - DOM, which has a link to the compatibility matrix:

DOM Support on Cisco Transeivers

Not all transceivers support DOM, a list of capable transceivers is available at:

DOM compability Matrix

How to use DOM

Following command can be used to turn on/off DOM for all transceivers type in the system

Router(config)#transceiver type all
Router(config-xcvr-type)#monitoring
Router(config-xcvr-type)#end

Once enabled, DOM can be accessed via CLI using show interface transceiver command
