This blog ETU-LINK will show you how to identify the wavelength of CWDM optical module through the color of the pull ring. We all know that CWDM has a total of 12 wavelengths, with a full band range of 1270-1610nm, with each wavelength interval of 20nm. The industry divides the entire band into front wave and back wave, with the front wave band of 1270-1450nm and the back wave band of 1470-16...
