Abstract

This application involves a wavelength locking method, device, light module, and wave -scoring reuse of light networks, which belong to the field of optical communication technology.This method is applied to the first light module in the optical network; the method includes: the wavelength of the wavelength of the target optical module adjacent to the end optical module corresponding to its own light module drift;The drift notice of drift of the module wavelength makes the target optical module respond to the ritten deferred wavelength, so that the wavelength is locked in the central wavelength position of the signal channel corresponding to the target optical module.When determining the wavelength of the target optical module of the adjacent adjacent channel, by sending a drift notice of drift by sending the wavelength of the target optical module, the target optical module is adjusted to the wavelength of its sending.The central wavelength position, so that additional optical devices do not need to be added, making the cost very low cost.

Description

technical field [0001] The application belongs to the technical field of optical communication, and in particular relates to a wavelength locking method, device, optical module and wavelength division multiplexing optical network. Background technique [0002] In a wavelength division multiplexing (Wavelength Division Multiplexing, WDM) system, such as a wavelength division multiplexing passive optical network (Wavelength Division Multiplexing-Passive Optical Network, WDM-PON) system, such as figure 1 As shown, the different wavelengths sent by all optical modules are combined by an optical filter (such as Arrayed Waveguide Grating (AWG)) and sent to the opposite end, and the opposite end is demultiplexed by the optical filter and then connected to each optical module . Each optical module has a sending end and a receiving end. The sending end can only send the optical wavelength corresponding to the corresponding channel. For example, optical module 1 can only send wavelen...
