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.

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. ~Seth
