HPE CWDM-SFP10G-1290-I Compatible SFP+ 10G CWDM 1290nm 40km DOM Duplex LC/UPC SMF Optical Transceiver Module for Transmission (Industrial)
P/N: CW-SFP10G40-29-I#112529
First, CWDM and DWDM have different wavebands, and the corresponding optical transmission schemes are different. Second, DWDM can be used with amplifiers, but CWDM modules cannot.

If you have a MUX, you can choose according to the channel range of the MUX, If there is no MUX and only the module is directly connected, then any wavelength can be choosed. They will all work well.

The main difference is the usable ambient temperature. If in a harsh environment, the industrial grade is recommend.

I was told by my AM that OEO can be used to convert non-WDM signals to WDM signals , and that you can use CWDM on your switch well
