Abstract
A transmitter includes a pilot loading apparatus, an optical modulator, and a pilot locking apparatus. The pilot locking apparatus is configured to determine a pilot operating point that is currently on a response curve and that is of the optical modulator, and a target initial amplitude of an electrical pilot signal. The pilot locking apparatus is further configured to control the pilot loading apparatus to adjust an initial amplitude of the electrical pilot signal to the target initial amplitude.
