摘要
提出了一种基于CDMA(码分多址 )的光纤接入方案 ,利用光纤信道的特点 ,可以实现上下行链路的同步通信并且简化发射机和接收机的设计 .该方案可以使用户使用最少的线路资源和低成本的用户终端方便灵活地接入网络 ,并且享有保证的通信带宽 .
In this paper, an optical access network based on CDMA is proposed. With the characteristics of fiber channels, we can realize synchronous communication on both the upward and downward links and simplify the design of transmitters and receivers. This idea enables subscribers to access the network flexibly with least line resource and low-cost user terminals. Furthermore, the bandwidth for each user is guaranteed.
