Compact Coarse Wavelength Division Multiplexer
紧凑型粗波分复用器
Dense Wavelength Division Multiplexing (DWDM) is a combination of a group of optical wavelengths that can be transmitted with a single fiber. This is a laser technology used to increase bandwidth on existing fiber backbone networks. More precisely, the technique is to multiplex the tight spectral spacing of a single fiber carrier in a designated fiber in order to utilize the achievable transmission performance (for example, to achieve the smallest degree of dispersion or attenuation). In this way, under a given information transmission capacity, the total number of optical fibers required can be reduced.
