On Epon Technology Features And Applications In Pinggu

The EPON technology application is day by day mature, the author participated in the link company Beijing Pinggu EPON network project plan design, the engineering construction and the implementation work. Through analyzes the actual problem which carefully earnestly the EPON technology in the application superiority, the application meets and explores positively solves the question method, elaborated the EPON technology application experience.First introduced based on the Ethernet technology's passive light network (EPON) and the EPON network's structure, the outline present mainstream's FTTx technology, the PON standard present situation, and described EPON to realize the principle, the key technologies and the technical superiority briefly.Analyzes the EPON technology in the user access network's application model, pointed out that the existing user access network existence constructs and maintains the cost to be high, the management not convenient, provides the service type to be unitary, band width low status insufficient. To EPON in the enterprise users and the public user access network's application model contrastive analysis, had proven the EPON technology application on-line has the obvious superiority in the enterprise users and the public customer turning on.Has further analyzed the Pinggu subsidiary company's special line service network existence safe hidden danger and the demand, proposed the solution:Uses EPON the turning on way, separates three individual line subscribers from the original network, and to LAN net separation item design exhaustive EPON turning on construction plan.Carries on the analysis to the EPON technology's practical application, and in the actual test and the following maintenance process through to the user service demand's analysis, the nimble utilization different data mapping, realizes the different user's QoS safeguard, different speed demand and so on.Finally, the author through uses the EPON way load bearing to Beijing link the service to carry on the analysis at present, summarized the EPON technology in this region practical application experience, pointed out that along with cost and so on optical fiber, equipment drops, each kind of application to the high band width's demand, will cause the EPON service to obtain a more widespread application and the development in the present.
