Optical communication system, method for controlling optical communication, and optical transmitter

摘要

An optical communication system includes an optical transmitter that sends an optical signal; and an optical receiver that receives the optical signal. The optical transmitter controls a transmission rate of the optical signal to a first transmission rate corresponding to first reception light power lower than target reception light power of the optical receiver in response to transmission light power control for the optical signal corresponding to the target reception light power.

主权项

1. An optical communication system comprising:
an optical transmitter that sends an optical signal; and an optical receiver that receives the optical signal, wherein the optical transmitter includes a controller programmed to perform transmission light power control, the transmission light power control including:
setting a transmission rate of the optical signal to a first transmission rate;increasing power of the optical signal output at the first transmission ratefrom the optical transmitter until a target power is reached which corresponds to a power of the optical signal being input into the optical receiver is equal to or more than a minimum receivable light power, the minimum receivable light power representing the minimum value of power of the optical signal that the optical receiver can receive; andcompleting the transmission light power control based on a response signal from the optical receiver; and the controller programmed to increase the transmission rate to a second transmission rate larger than the first transmission rate after completion of the transmission light power control.
