Fiber Optics and Mini CWDM In fiber optic communications, wavelength-division multiplexing (WDM) is a technique that multiplexes a number of optical carrier signals onto one strand of fiber by using different wavelengths. Two key WDM technologies are Coarse Wavelength Division Multiplexing (CWDM) and Dense Wavelength Division Multiplexing (DWDM). Which solution is best suited for a […]
