1. A first optical communication apparatus comprising
a signal light generator; and:
a frequency locker device configured to
generate a target wavelength control signal based on an optical frequency difference indication signal,
generate a target electrical modulation signal based on a target optical frequency difference, a target electrical frequency difference, and to-be-transmitted bit information, and
send the target electrical modulation signal to the signal light generator, wherein the target optical frequency difference is determined by using the optical frequency difference indication signal, the target optical frequency difference is a difference between the frequency of the external reference light and the optical carrier frequency of the first signal light, and the target electrical frequency difference is a difference between a measured electrical carrier frequency of second signal light sent by the signal light generator to the second optical communication apparatus and a target electrical carrier frequency, wherein
the signal light generator is configured to:
generate third signal light based on the target wavelength control signal and the target electrical modulation signal, and
send the third signal light to the second optical communication apparatus; and
the first signal light, the second signal light, and the third signal light are signal light output by the first optical communication apparatus at different moments.
