Optical Fiber Amplifiers for Multichannel Video Transmission and Distribution,

Abstract

In the last three years, optical amplifiers have been successfully used in numerous analog fiber optic systems to transmit and distribute multiple AM-VSB or FM video channels. Most technology issues regarding the usage of semiconductor optical amplifiers and erbium-doped fiber amplifiers (EDFAs) in those systems have been studied extensively. Therefore, the main purpose of this paper is not only to review the previous work, but also to compare the different technology aspects of analog and direct-detection digital video broadcast systems. This paper also addresses the potential evolutionary problems of using optical amplifiers in a subscriber loop that may need upgrading when distribution signals change from AM-VSB video to future digital video services.
