Wonder why is there a sharp price difference between these CWDM modules of CWDM-SFP25G-10SP(1270nm-1370nm) and CWDM-SFP25G-10M(1470nm-1570nm)? Are they different in any way?

Yes, my AM told me they are different in transmitter type. The transmitter type of CWDM module of 1470nm-1570nm is EML CWDM and that of the module of 1270nm-1370nm is DFB CWDM. EML devices are more difficult to produce and thus more costly. Por A***t en 23 de nov. de 2021
