Abstract

The invention provides an optical performance monitoring method and device, electronic equipment and a storage medium, and belongs to the technical field of optical performance monitoring in short-distance optical communication, and the method comprises the steps: carrying out the preprocessing of a to-be-processed SVDD signal, and carrying out the resampling; quantizing the trajectory information, and extracting hidden features in the trajectory information; and matching the hidden features. According to the method, accurate joint modulation format recognition, OSNR monitoring and RCD estimation can be realized on SVDD-BPSK, SVDD-QPSK, SVDD-8QAM, SVDD-16QAM, SVDD-32QAM and SVDD-64QAM. The requirements of short-distance communication on low calculation complexity, multi-parameter combined monitoring and high monitoring precision are met. Based on abundant difference characteristics contained in trajectory information, the method has the potential of being applied to backbone optical network and other linear or nonlinear damage monitoring.

Description

technical field [0001] The invention belongs to the technical field of optical performance monitoring in short-distance optical communication, and in particular relates to an optical performance monitoring method, device, electronic equipment and storage medium. Background technique [0002] With the widespread application of 5G, the Internet of Things and cloud computing, short-distance optical communication, that is, optical communication links that transmit hundreds of meters to tens of kilometers, and may reach more than 100 kilometers in the future, is moving towards long-distance, high-speed, low-speed optical communication links. Power consumption and other directions are developed to cope with the increasing capacity demand. Compared with the long-distance backbone network, the short-distance optical transmission network needs to deploy a large number of optical transceivers to connect different areas. Therefore, both system complexity and spectral efficiency are ke...
