摘要

提出了一种集单片机和波分复用技术于一体的光纤无线分配系统。单片机信号包含5个155 Mbit/s的数据通道，以18.5 GHz为中心，间隔450 MHz。该信号被直接调制到三个发射频率间隔为50 GHz的高速激光器上。在接收基站中使用布拉格滤波器，既可以解复用所需的光通道，又可以确保检测到的信号是单边带的(为了克服链路上的色散限制)。我们的结果表明，与背对背性能曲线相比，WDM信号解复用对系统性能的影响可以忽略不计。

Development of highly flexible broadband networks incorporating wavelength division multiplexing and sub-carrier division multiplexing in a hybrid radio/fiber distribution system

A radio over fiber distribution system incorporating both SCM and WDM technologies is presented. The SCM signal contains five 155 Mbit/s data channels, centered around 18.5 GHz with 450 MHz spacing. This signal is directly modulated onto three high-speed lasers with emission frequencies spaced by 50 GHz. Bragg filters are employed at the receiver base station in order both to demultiplex the required optical channel, and to ensure that the detected signal is single side band (in order to overcome dispersion limitations on the link). Our results show negligible degradation in system performance for the demultiplexing of the WDM signal compared with the back-to-back performance curves.
