基于EPON的三网融合通信服务系统的设计

Design of Communication Triple Play Service System Based on EPON

基于当前电信网、广播电视网和计算机网三网融合的社会背景及发展趋势,提出了一种基于EPON技术的综合通信服务系统模型;该模型中互联网端光信号、电信网端光信号直接通过FTTx接入以太无源光网络设备EPON,广播有线电视端数字有线信号通过射频、光发机处理后转换为1550nm光信号接入EPON;局端OLT使用ATCA架构,光分路器ONU端采用FTTH接入;结果证明该模型可实现三网综合信息的融合,具有一定的实用推广价值。

On account ot; the current social background and evolutionary tendency that the convergence of telecommunication, broadcast/television and computer networks is pushed forward, this paper presents an integrated communication service system model based on Ethernet Passive Optical Network （EPON）. FTTx is directly used in the optical signal of internet and telecommunications networks access to EPON. On the other hand, broadcast/television signal into 1550nm optical signal access to EPON is handled by Radio Frequency and Fiber Transmitter. ATCA architecture is used in the OLT. FTTH is used in the ONU. The result proves that the model can achieve integrated communication triple play. It has certain promoted value.
