Abstract

The invention provides a network wavelength drift suppression method and a system, and the method comprises the steps: collecting the parameter information, including the wavelength, of a laser in a network; decoupling the acquired parameter information to judge whether the wavelength of the laser is changed or not; if it is judged that the wavelength of the laser changes, sending configuration information to the laser; in response to receiving the configuration information, adjusting the wavelength by the laser. According to the network wavelength drift suppression method, the wavelength of the laser can be controlled and adjusted as required on the basis of monitoring the working state of the tunable laser.

Description

technical field [0001] The invention relates to the network field, in particular to a method and system for suppressing network wavelength drift. Background technique [0002] In optical networks, wavelength division multiplexing (WDM) technology is an important means to increase the transmission capacity of communication systems. Through wavelength division multiplexing technology, different wavelength channels can be transmitted in one optical fiber at the same time, so that the communication capacity can be doubled or dozens of times increased to meet the increasing demand for information transmission capacity. In order to make full use of the fiber bandwidth, it is hoped that the number of transmission channels will increase, and in order to ensure that the light wavelengths of N channels in one fiber can be in the lowest loss zone of the fiber, the WDM system requires the laser source to have wavelength tunability and a narrower Linewidth, and at the same time have str...
