Title:
OPTICAL TRANSCEIVER AND OPTICAL TRANSMIT/RECEIVE METHOD
Document Type and Number:
WIPO Patent Application WO/2018/159657
Kind Code:
A1
Abstract:
In order to suppress any reduction in the reception performance of an optical transceiver, the optical transceiver comprises a light source, an optical splitter that splits the output of the light source into a first split light and a second split light, an optical modulation unit that modulates the first split light, a coherent receiver that causes the inputted received light to interfere with the second split light, and a first control unit that controls the split ratio of the optical splitter on the basis of the reception characteristic of the received light received by the coherent receiver.
