基于干线系统光缆路由重构与实践

本文通过利用新建的高铁(高速)光缆,对现网受外部环境影响较深的干线传输系统通过对整个光复用段的光缆长度、色散补偿及光功率进行深度的分析,并对单波40G的色散补偿辅以三维仿真技术进行计算,进行相关色散补偿的增减,系统路由调整后,系统的各项指标正常。本文以局站1-局站2-局站3段落干线光缆的典型场景提供解决案例,进一步探讨如何及时结合新建的光缆网络资源优化现网干线传输系统,为提升干线传输网络健壮性提供解决思路和借鉴。

In this paper, by using the new high-speed optical cable, the trunk transmission system which is deeply affected by the external environment of the existing network, through the depth analysis of the optical cable length, dispersion compensation and optical power of the whole optical reuse section, and the dispersion compensation of single wave 40 G is calculated by threedimensional simulation technology, and the correlation dispersion compensation is increased or decreased. After the routing adjustment of the system, the indexes of the system are normal. This paper provides a typical case of 3-stage trunk optical cable from station 1 to station 2 to station 3, and further discusses how to optimize the trunk transmission system in time combined with the newly built optical cable network resources. the purpose of this paper is to provide solutions and reference for improving the robustness of trunk transmission network.
