Wavelength shift control method and system

A wavelength shift control method, wherein the method is applied to a wavelength shift control system, the system comprises Media Access Control (MAC), a controller, and a transmitter, wherein the transmitter comprises a laser, a heater, and an optical amplifier, wherein the laser fits both the heater and the optical amplifier, heat conducted by the heater to the laser when a switch of the heater is turned on matches heat conducted by the optical amplifier to the laser when a switch of the optical amplifier is turned on, and wherein the method comprises:

• generating, by the MAC, a burst control signal;
• sending, by the MAC, the burst control signal to the controller;
• and
• controlling, by the controller, switch statuses of the heater and the optical amplifier according to the received burst control signal, wherein when the switch of the heater is in an on state, the switch of the optical amplifier is in an off state, and when the switch of the heater is in an off state, the switch of the optical amplifier is in an on state, so that a temperature of the laser remains stable.
