The paper begins an investigation into the utility of the data entropy based 'quality budget method for optical telecommunications has recently arisen through the growing use of analogue optical amplifiers in what previously were exclusively digital fiber communication systems. The engineering of these now binary systems perhaps requires more than the established analysis tools of 'error budgets' and 'rise-time budgets'. The alternative 'quality budget' proposed and theoretically investigated here for the first time, seeks to directly link the measured output of systems to the measured performance of the system. This approach has previously been used very successfully to develop an amplitude modulated fiber optic system and delivered a very high 12-bit performance level for this AMFOS system. This new digital system application of the quality budget method provides a theoretical illustration of some of the most significant optoelectronic noise and loss components for both optoelectronic detectors and the laser source used in telecommunication systems. Demonstrations of using this approach of handling of the binary analogue and digital features are shown. Space restrictions do not allow a comprehensive analysis of the telecommunication issues and therefore simple quick reference tables of new results are used to condense the presentation of material. The data entropy description of digital signals is then investigated. The paper concludes with brief considerations into the advantages of this approach for the analysis of digital fiber systems using this two-sided approach to system performance quantification applying this integrated methodology for networking applications.
