Klymash M. The optical transport systems efficiency increasing.

Dissertation is devoted to the problem of optical transport systems development optimization which make basis of any national and international infocommunication network. An optical transport network is analyzed from the point of view network-dependent levels with account technical-economical features and strategy of development planning. The special attention is spared the common carrying capacity increase questions of optical transport systems; including fiber-optical nonlinear and polarization-mode dispersion effects method and automated system of compensation are designed. During a design this system showed that able to multiply the physical carrying capacity of the fiber in 1.7 - 5 times, depending on character of external influences and type of the applied fiber. Drawing on programmatic-designing complex is offered for the optimum configuring of transport optical systems equipment and carrying capacity maximization. For a calculation and design of properties and conduct of transport networks of telecommunications the computer system, with integrating in properties of basic algorithms of graphs processing, in particular most known algorithms of routing, was built. A possibility to analyze network of any configuration and complication degree work in different situations, including malfunctions appeared by the offered system. In work the topologies properties analysis of network structures is given and their applied application for optimization of transport networks topology, reliability parameters estimation and forming of theoretical base for informative streams management, topological-adopted routing and calculation are offered. The analysis of efficiency of the necessary technical resources use for optical transport systems is conducted, - ways, receptions, methods and facilities of increase of this index, are analyzed and developed.
