Optical emission apparatus, optical communication system, and optical communication method

An optical transceiver apparatus, comprising an optical emission apparatus, and further comprising:

• an optical receiving apparatus, a second optical splitter, and a photodetector;
• the optical receiving apparatus is configured to receive a light beam emitted by a peer-end optical transceiver apparatus, and transmit the light beam to the second optical splitter;
• the second optical splitter is configured to perform an optical split on the light beam transmitted by the optical receiving apparatus, and transmit, to the photodetector, a first partial light beam obtained after the optical split;
• and
• the photodetector is configured to detect an optical power of the first partial light beam, and return optical power information over a backhaul channel to the peer-end optical transceiver apparatus;
• wherein the optical emission apparatus comprises a first optical splitter, N optical emission units, wherein N is an integer greater than 1, and an adjustment unit;
• the first optical splitter is configured to receive signal light and transmit respective parts of the received signal light to each of the N optical emission units;
• the N optical emission units are configured to emit, based on the respective parts of the signal light received from the first optical splitter, light beams distributed based on a preset proportion that provides a higher optical power of the received signal light to one or more optical emission units in a center of the N optical emission units than to others of the N optical emission units;
• and
• the adjustment unit is configured to adjust, based on returned optical power information on the backhaul channel, the light beams emitted by the N optical emission units.
