  • Difference of DWDM and CWDM?

    The main difference from DWDM is that CWDM has a wider wavelength spacing than the wavelength interval of 0.2 nm to 1.2 nm in the DWDM system, and the standard wavelength interval in the industry is 20 nm. The wavelengths specified in ITU-T G.694.2 are shown in Table 1. The wavelength band to whi...
