(Facing the development trend of triple play, the radio and television field is transforming the traditional HFC one-way network into two-way transformation to provide two-way interactive services. The solution based on EPON has received a lot of attention. After analyzing and demonstrating in terms of cost, bandwidth, supported services, maturity and other aspects, EPON technology is the best solution for the bidirectional transformation of radio and television networks and the realization of triple play on HFC. in conclusion. It can realize the transmission of voice, data and TV signals under a single optical fiber, which greatly reduces the cost of laying optical cables and maintenance costs, and the transmission performance is more stable and reliable.)
