淺析電力通信網(wǎng)光纖保護通道黃麗妍 呂國遠(天津電力通信分公司 天津 300010)Analysis onOptical Protection Channel in Power Communication NetworkHUANG Liyan, LU Guoyuan(Tianjin Power Telemunication Company, Tianjin 300010, China)Abstract: The article briefly introduces the present situation of the optical protection channel in power munication 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 selfhealing ring of SDH. Key words: optical fiber munication。 SDH。 protection channel摘要:文章簡要介紹了電力通信網(wǎng)光纖保護通道的現(xiàn)狀;通過實驗,對SDH傳輸時延進行了測試和分析,證實了實驗所構(gòu)建的四條路由均滿足繼電保護對通信通道的要求,同時也提出了棄用SDH自愈環(huán)的建議。關(guān)鍵詞:光纖通信;SDH;保護通道3 / 3引言
