| Abstract: | EPON technology is the method, it can achieve radio and television networks cable two-way network transformation and it has the advantages of low cost and operational capacity. EoC simultaneous transmission in a coaxial cable TV and bi-direetional data signal can greatly simplifies two-way HFC network transformation. It can use of existing radio and television HFC networks to provide users with digital TV, interactive TV and broadband services. Radio and television networks make full use of the advantage of existing resources by EPON network. At the same time, EPON network construction let radio and television networks have the oper- ational capabilities of multi-service. |
