Analytical evaluation of the effect of amplifier noise on eye diagram for communication systems having PMD, PDL, and CD

摘要

We present an analytical method to evaluate the effect of EDFA amplifier noise on the optical eye diagram for the system having PMD, PDL and CD in dynamic fiber links for any given optical pulse sequence. The method considers a single EDFA amplifier at the end of a fiber and considers all orders of PMD and PDL of the fiber. It gives the time dependent average output light intensity as well as its corresponding variations as a function of the amplifier noise, PMD, PDL and CD. Also the performance of the system is discussed for various parameters as well as the effect of OSNR on the system's Q-factor.
