摘　　要：传统的传输网络存在传输容量小、传输速度慢等问题,为此应用5G技术,通过光纤的优化选择实现数字传输网扩容。建立数字传输网络模型,分析该模型在5G技术下的数字传输工作原理。对比目前市场中不同型号光纤的基础性能,在考虑成本的情况下选择性价比最高的光纤来取代传统的传输网光纤。通过提取当前流量数据、计算节点间中继距离和计算数据流量增长率三个步骤,确定目标传输网的扩容量。同时,在考虑传输网络拓扑不能实现完全分离与业务承载能力要求的情况下,保证同一接入路由器到核心路由的上层链路完全按部分分开。最后在数字传输网扩容同步保护下,通过光纤的更换以及相关传输参数的配置,实现数字传输网扩容。实验结果表明,与传统的扩容技术相比,该技术得出的结果更加接近扩容目标,且经过扩容处理网络的数字传输速度得到明显提升。The traditional transmission network has problems such as small transmission capacity and slow transmission speed.For this purpose,5G technology is applied to realize the expansion of the digital transmission network through the optimized selection of optical fiber.Establish a digital transmission network model and analyze the working principle of digital transmission of the model under 5G technology.Compare the basic performance of different types of optical fiber in the current market,and choose the most cost-effective optical fiber to replace the traditional transmission network optical fiber in consideration of cost.By extracting current flow data,calculating the relay distance between nodes and calculating the growth rate of data flow,the expansion capacity of the target transmission network is determined.At the same time,considering that the transmission network topology cannot achieve complete separation and the service carrying capacity requirements,it is ensured that the upper-layer link from the same access router to the core route is completely separated in parts.Finally,under the simultaneous protection of the expansion of the digital transmission network,the expansion of the digital transmission network is realized through the replacement of optical fibers and the configuration of related transmission parameters.The experimental results show that,compared with the traditional expansion technology,the results obtained by this technology are closer to the expansion goal,and the digital transmission speed of the network after the expansion processing has been significantly improved.
