Document Type and Number:
WIPO Patent Application WO/2021/031832
Kind Code:
A1
Abstract:
Embodiments of the present invention provide a wavelength division multiplexing system, a local apparatus, and a remote apparatus. The wavelength division multiplexing system comprises: a plurality of optical modules, and a pair of combiner/separator. The plurality of optical modules are respectively connected to the combiner/separator; the pair of combiner/separator is connected by means of an optical fiber link; central wavelength spaces of channels of the combiner/separator are equal; central wavelength spaces for sending light of the optical modules in adjacent wavelength channels are not equal, central wavelength spaces for sending light of the optical modules in odd numbered wavelength channels are equal, and central wavelength spaces for sending light of the optical modules in even numbered wavelength channels are equal.
