Abstract

Optical fiber cable transmission systems have advanced rapidly over the past ten years due to advances in fibers, lasers, and LSI's, and the system capacity has reached the gigabit/s range. The potential of optical fiber transmission systems is incredibly rich. The implementation of advanced optical technologies using optical amplifiers would enable the creation of more economical and higher quality systems [1]. In this paper briefly outlines recent studies on optical amplifiers, and describes their features. The impact of the new amplifier technology is then discussed, and the present and future possibilities for trunk and distribution networks are studied.
