Optimization of power optical transmission network based on photo-electronic hybrid cross-connection technology

对电力光传送网络的现状进行了初步分析,电力光传送网络面临着传送容量的不断提升、拓扑的日渐复杂、业务的灵活调度以及网络智能演进等巨大的挑战。采用光电分层交叉处理的思路,电层专注于小颗粒业务的汇聚收敛和超长距的电再生,光层则提供波长级别的灵活调度,基于无色、无向、无冲突、灵活栅格可配置光业务上下架构的CDC-FROADM技术优化网络架构,提升网络的传送效能,降低能耗和空间占用,赋能网络智能化的演进,同时极大节省网络建设和运维成本。

A preliminary analysis to the current situation of the power grid optical transmission network was made.The power grid optical transmission network is facing huge challenges such as the increasing transmission capacity,the increasingly complex topology,the flexible scheduling of services and the evolution of network intelligence.By adopting photoelectric layered cross processing,electric layer cross focus on small particles business convergence and long distance electric regeneration,optical layer routing provides the flexible wavelength routing,based on colorless,directionless,and contention less flexible grid configurable add/drop architecture CDC-F ROADM technology to optimize network structure,improve the network transmission efficiency,reducing energy consumption and space,which also benefits the evolution of network intelligence,and greatly save the construction and operational costs.
