Document Type and Number:
WIPO Patent Application WO/2022/024344
Kind Code:
A1
Abstract:
This optical transmission/reception system (10) is provided with a transmitter (101) having a light source for outputting NRZ optical signals of a plurality of different patterns, an optical fiber (13) for propagating the light of a plurality of modes, and a receiver (102) for receiving a multi-value signal generated from the NRZ optical signals and provided with a photodiode (15) and an optical waveguide (14).　Thus, it is possible to provide an optical transmission/reception system for transmitting/receiving a multi-value signal and provided with a compact transmitter and receiver.
