Description

technical field [0001] The invention provides a 100G non-coherent DWDM optical transmission system, which belongs to the technical field of communication transmission. Background technique [0002] Dense Wavelength Division Multiplexing (DWDM: Dense Wavelength Division Multiplexing) is the ability to combine a group of optical wavelengths for transmission with one optical fiber. This is a laser technology used to increase bandwidth over existing fiber optic backbones. More precisely, the technique is the multiplexing of close spectral spacing of individual fiber carriers in a given fiber in order to take advantage of achievable transmission performance (eg, to minimize dispersion or attenuation). In this way, the total number of optical fibers required can be reduced for a given information transmission capacity. [0003] Now, with the continuous development of communication technology, the communication capability of the DWDM optical transmission system is gradually impro...
