DESIGN OF A PERMITTED NETWORK USING FIBER-OPTIC-BASED SOLUTIONS MATHEMATICAL MODELING

Abstract

The main goal of the research is to increase the speed of exchange in broadband subscriber access networks, primarily using PON technology, since the needs of subscribers are constantly growing and modern structures can no longer provide them. This article discusses the PON technology, types of WDM technology, equipment designed for communication networks using WDM, designs and parameters of WDM multiplexers. The possibility of implementing WDM-TDM hybrid multiplexing in existing PON systems is considered. Conclusions are drawn about the relevance of the use of this technology in order to modernize existing access networks. The rapid development of technologies for the production of electronic optical devices and optical fibers made it possible in the mid-80s to use fiber to connect individual users and organizations. The launch of the first distribution networks was carried out using point-to-point topologies, but a few years later the technology of passive optical networks (PON) was created, which allows organizing point-to-point topologies.
