浅析电力通信网光纤保护通道黄丽妍 吕国远(天津电力通信分公司 天津 300010)Analysis onOptical Protection Channel in Power Communication NetworkHUANG Li-yan, LU Guo-yuan(Tianjin Power Telecommunication Company, Tianjin 300010, China)Abstract: The article briefly introduces the present situation of the optical protection channel in power communication network, and analyses the transmission delay of SDH by experiment
It is verified that the four routes which constructed in the experiment can meet the demand of relay protection, and it is proposed to abandon the self-healing ring of SDH
Key words: optical fiber communication; SDH; protection channel摘要:文章简要介绍了电力通信网光纤爱护通道的现状;通过实验,对 SDH 传输时延进行了测试和分析,证实了实验所构建的四条路由均满足继电爱护对通信通道的要求,同时也提出了弃用 SDH 自愈环的建议
关键词:光纤通信;SDH;爱护通道引言通信的两个重要指标是有效性和可靠性,由于继电爱护对电力系统的安全有着至关重要的阻碍,给通信专业提出了更高的要求:在保证传码率
