В статье показаны модели и методы построения широкополосных волоконно-оптических линий пе�редачи. Предлагается разработать сценарий модернизации информационно-коммуникационной инфра�структуры региональной сети передачи данных для увеличения максимальной скорости передачи по су�ществующим магистралям, обеспечения качества и надежности обслуживания. Описаны современные те�хнологии строительства волоконно-оптических линий передачи по принципу волнового распространения. Это также позволяет увеличить полосу пропускания, передавая различные модуляции сигналов перегру�зки кода по оптоволоконному кабелю. Данная технология позволяет повысить эффективность использо�вания волокна за счет распределения направлений распределения света и реализована в волоконно-опти�ческих элементах, имеющихся на отечественном рынке., The article presents models and methods for constructing broadband fiber-optic power transmission lines. To increase the maximum transmission speed along the existing transport routes, to ensure the quality and reliability of the service, it is proposed to develop a scenario for the modernization of the information and communication infrastructure of the regional data transmission network. Modern technologies for constructing a fiber-optic transmission line using the wave distribution principle are described. It also allows you to increase the bandwidth by transmitting various modulations of code signals in a fiber-optic cable. This technology makes it possible to increase the efficiency of the use of fiber by applying the distribution of distribution directions in the directions of propagation of the light flux and is implemented in fiber-optic elements available in the domestic market.

Web anonymization tools have been used for a long time, primarily by the users afraid of possible undesirable consequences of their on-line activity on the web. The paper analyzes both historically proven anonymization tools like TOR and newer tools, namely JAP/JonDo and CyberGhost VPN that are based on slightly modified technological principles. The primary focus is given to the measurement and evaluation of the latency increase and the transmission speed decrease in comparison to normal (non-anonymized) web browser operation. Results show that all anonymization tools being subject of the analysis provide relatively moderate latency increase. On the opposite, the transmission speed decrease was more significant, especially for JonDo. This confirms the conclusions of previous studies resulting that no anonymization tool is suitable for daily web browsing. On the other hand, in the case when higher anonymity is required, their use can be reasonably comfortable from the point of view of latency increase. However, their usefulness for downloading larger files is always disputable.
