Sun Wu Area Fiber-to-the-home (FTTH) Network Transformation System Design

Optical communication(OpticalCommunication)of a light wave as the carrier of communication.Optical fiber,photonic crystal fiber,optical fiber laser energy transmission and so on are all optical communication equipment.The data source and optical receiver,optical sender,optical channel is an essential part of the optical fiber communication system.PON(passive optical network)in just a few short years has quickly become accepted by most people and recognition of a fiber optic access.In the process of its development has laid a network access direction in the future.Passive optical network is now the highest utilization rate,a method of optical fiber to the home of its method is simple feasible,and has been widely recognized.Passive optical networks technically better than the traditional copper cable,it can be seen from the perspective of its constituent structure(made up of three parts:one is optical line terminal,the other is light distribution network,three is the optical network unit)is the most significant advantage rate and on the support of the business.Through the analysis of the geographical environment in the three areas and the business needs,the PON network technology has unique advantages in the rural access application:with the development of optical fiber door in our country,the optical fiber as technology mature slowly,passive optical network equipment and installation cost problem of the basic can meet the needs of rural areas of the net investment.First of all to optical fiber transmission medium from the traditional copper,thus reducing the investment in copper.Belongs to passive components and optical splitter,don't put it in the computer room,it can also reduce the cost of room and power supply.At the same time use P2MP passive optical network and single fiber bi-directional technology,it can greatly reduce the use of optical fiber and optical transceiver.Wuxian finally from the sun's broadband network to speed up the steps,broadband optical access network in copper retrofit scheme,rural FTTH cost analysis of three sides facing the sun wuxian country broadband network improvement were analyzed.
