Not CWDM, but we do have DWDM ER and ZR SFP+ in X2-SFP+ converter on 
8-port M1 linecards, and they work fine, DDM included.

They're all "Cisco compatible" optics i.e. have the right bits written 
into the EEPROM to emulate a vendor transceiver; you need "service 
unsupported-transceiver" for normal 3rd party optics, which I have 
tested but don't use in production, as we use reprogrammable optics.
