Evaluation of the Reliability of Fiber-Optic Information Transmission Systems Based on the Laws of Failure Distribution

The influence of various failure distribution laws on the reliability of fiber-optic data transmission systems (FODTS) components is analyzed. The article discusses the failure distribution laws applicable to hardware and software components of the system, which allow taking into account their interaction and mutual influence on the overall reliability of the system. As a methodology, reliability assessment models are used, in particular, the exponential distribution, the Weibull distribution, and the Musa- Okumoto software reliability model. Formulas for assessing the overall reliability of the system and probability density functions are given, allowing a more complete picture of the stability and reliability of the FODTS under operating conditions.
