摘　　要：本文以青藏铁路西宁至格尔木段为例,探究了OTN交换技术在铁路通信网络中的应用效果。文章首先介绍了基于OTN交换设备的铁路通信网络拓扑结构以及网络中波长选择开关、光放大器等核心元件的主要功能。随后设计了对照实验,仿真验证在无OTN交换和有OTN交换两种场景下,铁路通信网络的平均阻塞率和JFI指数。仿真结果表明,在应用了OTN交换技术的网络中,平均阻塞率更低,JFI指数更高。表明OTN交换技术的应用能够显著改善铁路通信网络的性能。Taking Xining to Golmud section of Qinghai-Tibet Railway as an example,this paper explores the application effect of OTN switching technology in railway communication network.This paper firstly introduces the topology structure of railway communication network based on OTN switching equipment and the main functions of the core components such as wavelength selective switch and optical amplifier in the network.Then,a control experiment is designed to verify the average blocking probability and JFI index of railway communication network in two scenarios without OTN switching and with OTN switching.The simulation results show that the average blocking probability is lower and the JFI index is higher in the network using OTN switching technology.It shows that the application of OTN switching technology can significantly improve the performance of railway communication network.
