Design And Realization Of Two-Way HFC Net Work Transformation Baseded On The Technology Of EPON+EOC/LAN

The cable television network has become the important component ofour country nation information infrastructure to the arrival of developmentalong with the science and technology and information times, and peoplemore and more attach importance to development and the utilization to thecable television network resource. The major merit of cable televisionnetwork before one covering our county can be transmitting the one-waybroadcasting type television program, and can not satisfy informationsociety people to the each other requirement of vocational workTherefore our county cable television networks need to be developed thesynthetical information network that the vocational work even more risedin value for providing was served from the broadcast television vocationalwork only developing the unity Therefore it is imperative that thetwo-way wire broadcasting television network branchery is transformed,the technology model to carry on the two-way transformation alsomakes us study carefully to learn.Several kinds of models that the two-way wire broadcasting televisionnetwork branchery was transformed has been analysed in this text, andcombines our county wire broadcasting television network branchery present situation society economy development of the reality that people'slife needs, and has put forward utilization EPON+EOC/LAN's technologymethod in the transformation of two-way HFC's network.This text has still carried on discussing of detail toEPON+EOC/LAN's technology of bilateral network transformationFirstly, the development from PON's technology spreads out, and thedetail has been introduced three of the OLT of EPON's system, ODN andONU/ONT's system component. Next carefully introduce the transferprinciple of EPON's technology with transmitting the principle. Oncemore, the introduction still has been in progress to other methods ofbilateral network transformation by this text, so that the better combinesthe technology model to select the transformation that self is real.By way of the research work of this text, the technology method oftwo-way HFC's network transformation has done exploring of profitable,and also gives our county wire broadcasting television network two-waytransformation of branchery to have provided feasible EPON+EOC/LAN'stechnology model.
