淺析電力通信網(wǎng)光纖保護(hù)通道(留存版)
【正文】 2M時(shí)隙通過網(wǎng)元的時(shí)延T1=(TC/2－T0)/13=83us 以T0、T1為基礎(chǔ)計(jì)算D路由的2M雙向時(shí)延TFTF=（T0+T1*18）*2=3050usTF與實(shí)際測量值TD（5307us）相差很遠(yuǎn)，由于D物理路由長，此時(shí)物理光路產(chǎn)生的時(shí)延也應(yīng)考慮。淺析電力通信網(wǎng)光纖保護(hù)通道黃麗妍 呂國遠(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。 測試數(shù)據(jù)經(jīng)過多次測試取平均值，
