It is possible we don’t know what we were doing, but we  could not get all the 
data on non cisco SFPs.  They still worked OK.

  There is something special embedded in Cisco SFPs that the equipment can 
detect.  Generic SFPs can be detected.  
  Kinda like a generic non HP print head in an HP printer.

  Cisco gear doesn't know jack difference if you program the SFP properly.  ;-)

  Don't count on non cisco branded SFP to be able to give you all the data 
  metrics like RX power TX power etc.  Cisco gear knows when it is not talking 
  to its own stuff and will refuse to give you full features.

  No, you need CWDM SFPs in the right wavelengths, standard non-colored
  optics will not work.

  See the list in Table 3 here:
  
http://www.cisco.com/c/en/us/products/collateral/interfaces-modules/cwdm-transceiver-modules/product_data_sheet09186a00801a557c.html

  You don't need to use a Cisco-branded SFP, any with the right
  wavelengths will work.
