Abstract

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.

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
