摘要

世界上商用调频（FM）转换模拟无线电光纤系统的最长传输距离超过300公里。该系统将频率为90兆赫至2.1 GHz的社区天线电视/广播卫星/通信卫星视频信号进行多路复用，将其转换为光信号，并从广播大楼传输到用户家中。在调频转换系统中，色散补偿光纤（dcf）用于补偿传输光纤中产生的色散。然而，由于DCF长期消耗的风险，有必要考虑替代色散补偿配置。因此，我们提出了一种啁啾光纤布拉格光栅（CFBG）色散补偿配置，并使用该配置进行了调频转换远距离传输实验，并评估了其适用性。我们澄清，与使用dcf相比，在传输光纤前面布置cfbg可以提高载波噪声比。

310-km FM-Conversion A-RoF-Transmission Experiment Using Chirped Fiber Bragg Gratings

The world’s longest transmission distance for a commercial frequency modulation (FM)-conversion analog-radio over-fiber system exceeds 300 km. This system multiplexes community antenna television /broadcasting satellite / communication satellite video signals with frequencies from 90 MHz to 2.1 GHz, converts them into optical signals, and transmits them from the broadcaster building to customer houses. In the FM-conversion system, dispersion compensating fibers (DCFs) are used to compensate for the chromatic dispersion generated in the transmission optical fiber. However, due to the risk of DCF depletion in the long term, it is necessary to consider alternative dispersion-compensation configuration. Therefore, we propose a chirped fiber Bragg grating (CFBG) dispersion-compensation configuration and conducted an FM-conversion long-distance- transmission experiment using this configuration and evaluated its applicability. We clarified that the carrier-to-noise ratio is improved by arranging CFBGs in front of the transmission fiber, compared with using DCFs.
