摘要

本文介绍了用于微波信号传输的商用模拟光纤链路主要特性的实验研究结果。对两种类型的发射机进行了测量:通过激光注入电流调制直接调制法布里-珀罗谐振腔激光发射强度和在马赫-曾德尔调制器中外部调制DFB激光发射强度。测量了发射机输出调制辐射的光谱和模拟链路光电探测器模块输出频率高达18 GHz的相应信号的光谱。特别注意了链路收发模块和接收模块的时延测量。

Main Characteristics Study of Analog Fiber-Optic Links with Direct and External Modulation in Transmitter Modules

The results of experimental studies of the main characteristics of commercially available analog fiber-optic links for microwave signals transmission are presented. The measurements were carried out for transmitters of two types: with direct modulation of Fabry-Perot resonator laser emission intensity through laser injection current modulation and with external modulation of the DFB laser emission intensity in the Mach-Zehnder modulator. Both the optical spectra of the modulated radiation at the transmitter output and the corresponding spectra of signals with a frequency band up to 18 GHz at the output of photodetector modules of analog links have been measured. Special attention was paid to time delay measurements into links' transceiver and receiver modules.
