Optical communication apparatus and optical communication system

An optical communication system comprising:

• a first optical communication device that transmits a first optical signal through an optical fiber;
• a second optical communication device that receives the first optical signal transmitted from the first optical transmission device through the optical fiber;
• and
• a management device that communicates with the first optical communication device and the second optical communication device,
• the second optical reception device includes:
• a light-receiving device that receives the first optical signal and converts the first optical signal into an electrical signal;
• a first measurement circuit that measures a first average power and a modulation power of the first optical signal based on the electrical signal;
• a light-emitting device that transmits a second optical signal to the first optical communication apparatus by emitting light in accordance with a driving current;
• a driver that causes the light-emitting device to transmit the second optical signal according to a transmission signal by controlling the driving current based on the transmission signal;
• and
• a processor that
• generates a first control instruction to adjust the first optical signal based on the first average power and the first modulation power;
• transmits the first control instruction to the another optical communication apparatus;
• receives a second control instruction based on a second average power and a second modulation power of the second optical signal from the another optical communication apparatus;
• and
• adjusts the driving current based on the second control instruction,
• the management device:
• receives information regarding the light-emitting device from the second optical communication device.
