Design And Implementation Of Simulation Software For Operation And Maintenance Of Submarine Optical Cable Communication System

With the rapid development of submarine optical cable communication systems around the world,it has undertaken the transmission of more than 97%of the world’s Internet transoceanic data and long-distance communication services,and has built and developed high-speed,large-capacity,and high-reliability submarine optical cables.Communication systems have become an essential part of communication in today’s era.The ever-expanding submarine optical cable communication network scale and changes in the communication capacity brought about by wavelength division multiplexing(WDM)have brought new requirements and new challenges to the maintenance and upgrade of the submarine optical cable communication system.Design and implementation A software specially used for submarine optical cable operation and maintenance simulation is an urgent need to improve the communication operation and maintenance management level of submarine optical cables.This paper analyzes and designs a submarine optical cable communication system model based on WDM technology for the operation and maintenance management requirements of submarine optical cable communication.And realized a submarine optical cable communication system operation and maintenance simulation software.The main work and achievements of the paper are as follows:1.Investigated the submarine optical cable communication system;studied and designed the submarine optical cable communication system model;explained the functions and structural principles of each part of the model.2.The operation and maintenance optimization method of submarine optical cable communication system is studied;an ANN-based WDM system transmission performance prediction model is proposed.Experiments show that the model can predict the Q factor more accurately,and can output multiple Estimated Q-factor of the channel.3.Analyzed the requirements of the operation and maintenance simulation software of submarine optical cable communication system,and divided the software into eight modules according to the requirements,namely network display module,data management module,system configuration module,system simulation module,performance analysis module,performance prediction module,auxiliary management module,component library module;the scheduling of simulation tasks is optimized by using OpenMP for parallel computing;finally,the function and implementation of each module of the software is introduced,and the interface design of the main function window is shown,and the realization of The operation and maintenance simulation software for submarine optical cable communication is developed to meet the needs.
