Will the SFPs from the ONS systems work in a cat6500? There's a plethora of ONS-SC-2G SFPs out there, but not so many DWDM-SFP-xxxx modules. I'm guessing that the disparity in supply means they don't work, but would like some confirm. (Have a temporary need to run a gig over a DWDM wave, looking for the cheap way out.)
