摘　　要：阐述了目前无锡供电公司光通信网络中4种成功运用的传输保护方案:简单SNCP、单节点互连层叠式SNCP、双节点互连层叠式SNCP和复用段共享环保护(MS-SPRING)。通过运行实例来具体说明其保护方式、机理和应用场合,并进行综合比较,以此提出了无锡地区"2007年—2010年"通信网建设中应采用的保护方案,从而提高通信网的可靠性来保障电力生产的安全稳定性。Four transmission protection schemes successfully applied in current optical fiber communication network of Wuxi Power Supply Company are presented, including simple SNCP, single-nod interconnecting laminating SNCP, double-nod interconnecting laminating SNCP and MS-SPRING. The protection mode, mecha nism and application occasion are described with operation cases. Furthermore comprehensive comparison is performed and the proper protection scheme in Wuxi area communication network construction during the year of 2007-2010 is proposed, so as to improve reliability of communication network and secute the stable operations of power network.
