Analytical Expressions and Model of Optical Communication Network Reliability Index Estimation

Delivery of broadband services to subscribers on the basis of optical components is based on optical access networks. The article presents the types of network topologies that are relatively easy to organize by analyzing the structure of a passive optical communication network. In particular, on the example of passive optical networks, several types of topology were analyzed and a reliable and easily organized type of topology was selected. Reliability models of passive optical communication networks have been developed, and analytical expressions of a number of reliability indicators of the network on these models have been developed. These models allow to design a passive optical network for communication subscribers located in scattered areas and to study its reliable operation. These models make it possible to design a passive optical network for communication subscribers located in scattered areas and to study its reliable operation. Based on these analytical expressions, it is possible to determine the reliability index of subscribers of a certain region. On the basis of the mentioned architecture, it is possible to achieve a high level of the reliability indicator of the optical communication zone. It provides a backup architecture using the analysis results of the previous architectures. We created each of the images below using Microsoft Visio.
