Method and apparatus for controlling wavelength of optical module, and storage medium

Abstract

A method and an apparatus for controlling a wavelength of an optical module, and a storage medium. The method comprises: determining an initial temperature compensation curve corresponding to a transmitter optical subassembly TOSA in an optical module (S); obtaining a first control voltage to be applied to a TEC according to a current ambient temperature and the initial temperature compensation curve; and controlling the TOSA to emit a first light wave based on the first control voltage, whose wavelength is a first wavelength (S); when the first wavelength does not meet a setting range, adjusting the control voltage applied to the TEC until the control voltage applied to the TEC reaches a second control voltage, the second control voltage being capable of controlling the TOSA to emit a second light wave at the current ambient temperature, whose wavelength is a second wavelength meeting the setting range; and updating the initial temperature compensation curve based on the second control voltage (S).
