Title:
SIGNAL SENDING DEVICE AND METHOD, SIGNAL RECEIVING DEVICE AND METHOD, AND OPTICAL TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/134909
Kind Code:
A1
Abstract:
A signal sending device and method, a signal receiving device and method, and an optical transmission system, relating to the field of optical communications. The signal sending device comprises a modulating and multiplexing module and a sending module; the modulating and multiplexing module is used for modulating and multiplexing n optical signals having different wavelengths to obtain target optical signals; the target optical signals comprise a first optical signal and a second optical signal; the wavelength of the first optical signal is different from the wavelength of the second optical signal; the first optical signal and the second optical signal carry associated data signals; the sending module is used for sending the target optical signals to an optical link; the signal receiving device comprises a receiving module and a photoelectric conversion module; the receiving module is used for receiving the target optical signals by means of the optical link; and the photoelectric conversion module is used for performing photoelectric conversion on the target optical signals to obtain target electrical signals. In the present application, the optical signals carrying the associated data signals can be transmitted in a superposition manner, such that the effect of amplifying the optical signals and the data signals is achieved, and the reliability of the optical signals and the data signals during long-distance transmission is ensured.
