【正文】 In addition there is a doubleloop fiber optic MODEM with selfhealing function. This feature greatly enhance the reliability of the munication. the signalis not affected while the main station to send the appropriate alarm andpositioning signals so that maintenance personnel section of cable fault the characteristics of optical fiber municationLarge capacity optical fiber munication with the munication theattenuation is small not afraid of lightning antielectromagic interferencecorrosion resistance confidentiality reliability and easy installation but therelatively high investment costs especially for inner city buried cable lines fiberlaying construction costs will be optical fiber munication implementations in distribution worksOptical fiber munications work formation is very flexible and can frame intoa star chain tree mesh single fiber work dualfiber work ringmultibranch multiring intersection tangent and other multiring to the characteristics of distribution automation systems fiber optic ring usually made up of work and puter local area work connectiondata She Ji practical engineering the fully take into account the special worktopology power structure of munication plexity SDH transmissionsystems can use up to 126 E1 2M I Quan cross Lian Jie He pairs the mainbranch of halo more than the design of Si Xiang Guang. The basic framework of1 to 3 SDH/STM1 dualfiber selfhealing intersect or tangent and whennecessary can change the way light card online upgrade SDH/STM4. If theBureau of the work control center is located in the geographical center of theLAN the proposed design for the tangent to the ring to dispatch center as thecutoff point if the Board deviated from the work control center LANgeographical center of the proposed design for the intersection ring because notdispatch center intersection in order to reliably between the adapter ring the ringat least two points intersect each other to protect ConclusionIn the actual distribution automation munication system must build alow cost high effective twoway munication system with acceptablereliability and cost of information flow to provide very high because of distribution automation system functions to be acplishedby too many plex systems a single munication system to meet the needsof all of the functions is unrealistic and it is not economical.
