A) Those are CWDM GBICs/SFPs, not DWDM GBICs/SFPs.

B) Spamming an operations list with parts for sale is a bad idea.

C) Be wary, there are a TON of fake Cisco optics (especially in CWDM) 
   coming out of asia and floating around the used markets right now. 
   Sometimes they work, sometimes they don't. Sometimes they install 
   the GBIC innards inside the shell upside down and misspell 
   "transceiver" on the "cisco" label too.
