EPON technology and the application of rapid development , has become the hot spots of the international scope of technology , the Jiangxi mobile also actively involved in the trials and construction of EPON . I participated in the test , construction and implementation of a of Shangrao mobile EPON project , including EPON, laboratory and field test program development, test and implementation , the paper comes from the enterprise project . The paper first introduces the Ethernet passive optical network (EPON) and EPON network structure , summed up the mainstream FTTx technology , PON standard status quo , and a brief description of the realization of the principle of EPON , key technologies and technological advantages . Thesis focus on the composition of the EPON system , introduced the OLT, the ONU ODN ( Optical Distribution Network) design principles , which focuses on the ODN part . Thesis domestic mainstream EPON equipment supplier ZTE equipment , for example , FTTB, FTTx technology application mode to provide an example of universal design , and on this basis the EPON system splitting ratio selection and fiber optic cable transmission distance calculated method to provide a basis for EPON system design template . Followed by the practical application of project - Jiangxi Medical College Shangrao Branch dormitory EPON broadband access projects , analysis the EPON technology applications in the important group of customers access advantages , engineering feasibility analysis, and network -building programs , and describes the related equipment and based on EPON system performance testing , test on the actual performance of the pilot project demonstrated the feasibility and advantages of EPON Group customers access , access community , further elaborated EPON technology is mature , the performance indicators meet existing network applications to replace existing telecommunications technology to provide users with a variety of communication services solutions , it is more feasible in the future as a communication access technology . Final conclusion: the development trend of fiber access is the access network , EPON technology has gradually matured , and the declining cost , fully functional , EPON technology will be applied more and more widely used at home and abroad .
