Title:
OPTICAL TRANSMISSION SYSTEM, OPTICAL RECEPTION DEVICE, AND OPTICAL TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/029832
Kind Code:
A1
Abstract:
This optical transmission system comprises a plurality of optical transmission devices and an optical reception device, and performs communication by wavelength division multiplexing, wherein: each of the plurality of optical transmission devices comprises a transmission unit that encodes transmission data on the basis of an allocated code, and outputs the encoded transmission data to an optical transmission path at an allocated wavelength; different codes are allocated among the plurality of optical transmission devices to which different wavelengths have been allocated; and the optical reception device comprises one or more decoding units that decode transmission data transmitted from the plurality of optical transmission devices on the basis of the allocated code and an optical signal for each wavelength transmitted via the optical transmission path by wavelength division multiplexing.
