【正文】 節(jié)較少，故障處理容易，但纖芯利用率太低，且受傳輸距離約束[2]。關(guān)鍵詞：光纖通信；SDH；保護(hù)通道3 / 3引言通信的兩個(gè)重要指標(biāo)是有效性和可靠性，由于繼電保護(hù)對(duì)電力系統(tǒng)的安全有著至關(guān)重要的影響，給通信專業(yè)提出了更高的要求：在保證傳碼率和誤碼率的同時(shí)，對(duì)通道的時(shí)延也有著嚴(yán)格的要求。淺析電力通信網(wǎng)光纖保護(hù)通道黃麗妍 呂國(guó)遠(yuǎn)（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。本文
