Study On The Application Of EPON Technology In The An

The press of IP traffic that enriches colorful multi-media traffic and presents a burst type growth day by day makes higher request to the bandwidth of correspondence net. The shape of top speed area net in the office and big capacity framework net makes to take ADSL as main connecting to commence the connecting of the consumer of segment into the net and becomes corresponding by letter the bottleneck that the net deveolps toward"the broad - bond electrical noise turns, loading the IP turn, the traffic synthesis turn" direction. Operator's network can sustain a shape and want to consider the previous period invest of network, and want to give attention to both follow-up network evolution to upgrade capability. The EPON technique went in to lead to go into ether net and PON in the net in the connecting and blended an existing technique, and pass to expand DBA and OAM, strengthened traffic suitability and operation to support supervision capability, made the network support in brief and be easy to upgrade;After following of Chinese telecommunication, test, among nations lead off carried out completely, large-scale mutual communication, domain chain quickly deveolp, the EPON equipment comes to a to carry a camp class request;The series turns of ONU equipment appearance, satisfy various scene down of the network deploy a requirement. EPON has already forminged scale in Chinese the telecommunication south in the province at the consumer's connecting into the application of net level and just and gradually launches in the north and supports system and maintenance regulations to gradually forming, the PON traffic IT flow process the realize automate;Equipment function, performance and stability, the net scale continuously promotes in the run - time now and perfect, become FTTx constructive head to choose and represent broad - bond electrical noise connecting to lately deveolp a direction into the technical.The author took part in BaiShanDianXin transmission layout, construction and implementation operate of the net, include connecting EPON into the net level broad - bond electrical noise small zone construction, remould task.This thesis comes from the construction, remould of business EPON fulfillment item.Is textual to choose be take these items as back ground, progress EPON technique at connecting go into the application study in the net.Pass an analysis search, backlog related experience, for EPON technique, equipment now net amid of concrete application lay solid foundation.This text passes butt joint into the present condition of the net and the analysis of the existence question and elaborated to connect into a net to lead into a technical necessity of EPON;The synopsis described the priniple, system structure, key technique, technique characteristics, main advantage, standard present condition and shape trend of carrying out of EPON;Emphasized to describe to pass business standard a test of medium interest EPON equipment and its performance.The point of thesis is analysis to go into a net to apply according to the connecting of EPON equipment.Combine Chinese telecommunication draws up of total shape way of thinking, priniple and strategy, connect into net present condition to the local consumer, exist a problem and deveolp an object, set net technique select and EPON lead go into and evolve, and network layout of priniple, application the scene, technique scheme carried on analysis, give the local consumer connect into a net of EPON solution.After local consumer connects into the net adoption EPON technique set net, the correspondence net turns to the flat even network structure, network loading the IP turn, correspondence the traffic synthesis turn a direction to move forward further.
