Optical module signal processing method and device and optical module

Abstract

The invention provides an optical module signal processing method and device, and an optical module, and relates to the technical field of optical communication, and the method comprises the steps: obtaining the signal-to-noise ratio information of a first low-speed top adjustment signal when the condition that an optical detector of the optical module receives the first low-speed top adjustment signal with first low-speed management data is monitored; determining a target demodulation mode of the first low-speed top adjustment signal according to the signal-to-noise ratio information, whereinthe target demodulation mode comprises a first demodulation mode based on a received data conversion unit and a comparator and a second demodulation mode based on an analog-to-digital converter; anddemodulating the first low-speed top adjustment signal according to the target demodulation mode to obtain first low-speed management data. In this way, for different receiving scenes, the demodulation mode of the first low-speed management data is flexibly selected based on the signal-to-noise ratio information of the first low-speed top adjustment signal, the communication efficiency and the communication quality between the optical modules are improved, and therefore the user requirements are met.

Description

technical field [0001] The present invention relates to the technical field of optical communication, in particular to an optical module signal processing method, device and optical module. Background technique [0002] The optical module is an important component of the modern optical communication network, which provides a Gbit high-speed data physical channel for the communication network. With the increase of the complexity of the optical module, in some application scenarios, in addition to the high-speed data channel as the main data transmission between the optical module and the optical module, it is also hoped to establish a simple and low-speed data channel to facilitate the fast communication between the optical modules. Negotiate, monitor and manage communications. [0003] In the prior art, the topping information is mainly used in the application of the wavelength division system, and the low-speed management data is superimposed on the high-speed transmission...
