Title:
OPTICAL COMMUNICATION DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/142695
Kind Code:
A1
Abstract:
The present application relates to an optical communication device, comprising a first laser, a second laser, an optical path assembly, a first modulator, a second modulator, a polarization rotation beam combiner and a signal processor, wherein the first laser emits a first beam, the wavelength of which is a first wavelength, and the second laser is used for emitting a second beam, the wavelength of which is a second wavelength; the optical path assembly outputs part of the first beam to the first modulator, and outputs part of the second beam to the second modulator; the first modulator modulates a first electrical signal onto the part of the first beam, so as to obtain first signal light; the second modulator modulates a second electrical signal onto the part of the second beam, so as to obtain second signal light; the polarization rotation beam combiner performs polarization rotation beam combination on the first signal light and the second signal light, so as to obtain beam-combined signal light, and sends the beam-combined signal light to a second optical communication device; and the optical path assembly sends the other part of the first beam and the other part of the second beam to the second optical communication device.
