新型全业务光缆网络设计

Design on New Full-service Optical Network

为了应对日益剧烈的全业务竞争压力,旧光缆网络已不再适应业务拓展需求,设计新型全业务光缆网络成为当务之急。参考SDH网络模型,以承载业务带宽、级别及设备类型为依据,进行分层次网络模型设计。通过各层网络功用及适用场景分析,设计各层网络组网模式。以配线层光缆网为重点研究对象,提出独享与共享两套纤芯接入方案。通过设计高利用率、高光缆效能的混合接入方式,实现了全业务光缆网的高效运行。

In order to cope with increasingly intense competitive pressure of full-service, the old optical network could not meet needs of business development and it＇s necessary to design a new full-service optical network. Using the SDH network as a model, based on service bandwidth and level, a hierarchical network model is designed. Through the analysis of the network function and application scenarios, different layers network is designed. To focus on the wiring layer, the shared and exclusive core access methods are proposed. Through the design of high efficiency, high-effect converged mesh, the full-service network＇s efficient operation is ensured.
