| 摘 要： | 设计了一种将光载无线技术融合于波分复用无源光网络结构的系统。在发射端,系统采用光学倍频技术生成40GHz光毫米波载波,加载2.5Gbit/s的基带数据信号,下行链路传输性能良好且受色散影响小;在接收端,利用光波重用技术从下行信号中提取上行光载波,加载2.5Gbit/s上行基带数据信号。采用光学倍频技术降低了毫米波生成成本,提高了系统的实用性。

| Abstract: | A system integrating the techniques of radio over fiber(ROF) with wavelength division multiplexing(WDM) is designed.In the transmitting terminal,optical frequency multiplication(OFM) is used to generate 40-GHz optical millimeter-wave and carry 2.5-Gbit/s baseband signals,therefore,the performance of the downlink transmission is good and the effect of dispersion is small.In the receiving terminal,it extracts the uplink subcarrier from downlink signals with wavelength reuse technology and realizes the transmission of 2.5-Gbit/s baseband signals.The OFM technique decreases the cost of millimeter-wave generation and improves the applicability of the system. |
