Abstract

For the first time the term data diffraction is introduced, with examples drawn from the algorithm known as phase coherent data-scatter (PCDS) that produces identifiable visual patterns for different types of signal degradation in optical telecommunications. The main signal degradation factors that affect the performance of optical fibers include attenuation, rise-times and dispersion. The theory behind data-scatter is introduced including comprehensive explanations of the theoretical conceptual components of this technique such as centroids, exchange operation, coherence, closeness and projection radius. The various issues of assessing the quality of digital signals are outlined using a simulation study. The authors for the study of optical telecommunications issues have extended the functionality of data-scatter. This approach shows considerable promise. The utility of the data-entropy based 'quality budget method' for optoelectronic system engineering is revisited using an information theory based approach for optical telecommunications. Proposals for the implementation of pattern recognition algorithms to analyse the repeatable patterns within data-scatter are discussed. The paper concludes with brief considerations into the advantages of linking the new data-scatter and data-entropy approaches in digital fiber systems for performance quantification and assessment.
