APPLICATION OF MONTE CARLO SIMULATION TECHNIQUES TO OPTICAL FIBER COMMUNICATION LINK MODELS

摘要

Standards bodies typically model network links using worst-case link models in their standardization efforts. While these efforts have been exemplary, the worst-case model does not foster an understanding of the expected link performance or how tradeoffs of component specifications may increase link performance. Thus, limiting the network designer's choices in link implementations. A unique approach to this problem, providing a better understanding of the link performance, may be obtained by applying Monte Carlo simulation methods to the link models. To demonstrate the usefulness of this link modeling method, test results have been compiled to produce the necessary real world distributions as input to the simulation. The results of the simulation allow one to analyze the resultant link distance and power penalty probability distributions. One may then choose a confidence level required for the link performance as opposed to resorting to the worst-case scenario. Optimization of each component's key parameters may also be examined when utilizing this technique.
