Abstract

The performance of coherent transmission systems with optical amplifiers is limited by factors such as gain saturation and the accumulation of spontaneous emission. The spontaneous noise is conveniently modelled by the amplifier noise figure which can be used to predict the performance of amplifier cascades. The ultimate transmission loss limit of an optical amplifier cascade is discussed and the requirements of amplifiers to achieve a trans-ocean communication link are described. Other limitations to amplified systems such as dispersion echo signals from reflections and interchannel interference are also discussed.
