Dense Wavelength Division Multiplexing(DWDM) systems are an important part of modern long-haul backbone networks and metropolitan networks. In long-haul transmission applications, fiber attenuation and dispersion are the main factors affecting optical signal transmission, so active devices such as Erbium Doped Fiber Amplifier (EDFA) and Dispersion Compensator (DCM) are commonly used in Dense Wavelength Division Multiplexing (DWDM)… Continue reading Do you know the EDFA and DCM in DWDM system
