面对三网融合的发展趋势,广电领域正在将传统的HFC单向网络进行双向化改造,以提供双向交互式的业务。基于EPON的方案获得了很大的关注,在成本、带宽、支持业务、成熟度等各方面进行分析论证得出EPON技术是广电网络双向改造、在HFC上实现三网融合的最佳使用方案的结论。它可以实现语音、数据、电视信号在单一光纤下传输,这大大降低了铺设光缆的费用及维护成本,而且传输性能更加稳定、可靠。

(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.)
