The results of comparative analysis of methods for information extracting from optical fiber lines are presented. The classification of extraction methods, physical conditions for leak channels formation is given. In addition, methods making it possible to remove part of the optical radiation to outside of the propagation medium are given. A technique is proposed for detecting the fact of the information leakage channels formation. A number of different ways for the detection is described to successfully combat unauthorized access. The analysis showed that the simplest detection method is bending of optic fiber in order to eliminate total internal reflection. In this case, to monitor and detect fiber bends it is necessary to track the introduced losses. The structure, operation principles and trends in monitoring systems development are given.","PeriodicalId":255578,"journal":{"name":"2020 Systems of Signal Synchronization, Generating and Processing in Telecommunications (SYNCHROINFO)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130260856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the same time, the problem of automatic antenna matching in a wide frequency range has become more actual. PIN diodes are widely used in radio transmitting and receiving devices from high frequencies to microwaves. With their help, attenuators, phase shifters and two-way switches may be implemented. The use of PIN diodes, which are switching elements of the microwave range, in the high-frequency range imposes certain restrictions both on the magnitude of the maximum switched current and on the amplitude of the control signals. An analysis of the achievable power values of HF automatic antenna tuning unit (ATU) switched using by PIN diodes showed that in the case of a matched load, they can be used up to power levels almost equal to 2 kW in the HF range. With a strong antenna mismatch, the maximum power levels are reduced to 170 W when operating at frequencies above 3 MHz and to 100 W when operating at frequencies above 1 MHz.","PeriodicalId":255578,"journal":{"name":"2020 Systems of Signal Synchronization, Generating and Processing in Telecommunications (SYNCHROINFO)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134369641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Intellectualization of integrated management systems using robotic systems and complexes is presented comprehensively at the level of organizational, organizational and resource (taking into account their decomposition into organizational-information, organizational-cognitive, organizational-technical) and technical-technological processes. The main features of target processes in the life cycle of an integrated control system when including functional systems based on robotic systems and complexes in its composition are given. The complete group of target processes is considered. This approach is universal and is proposed to describe the structure of counteracting processes that have an artificial origin. In the lifecycle of integrated systems. The main content of developers' work on providing target processes at the stages of the integrated management system life cycle is considered: research, development, testing and operation of integrated management systems. It is shown that organizational and resource processes are the most flexible and capable of prompt adjustment at the operational stage. The article considers the development trend of integrated management systems as network-centric systems that allow for the reallocation of resources for the implementation of the main functions of the system. On a process basis, in accordance with the system triad, which includes the principles of openness, non-linearity and coherence, the conditions for implementing synergetic properties are considered. For this purpose, conditions should be created for the emergence of synergetic processes within the full group of processes aimed at implementing functionality. To create such conditions should be identified and promptly addressed vulnerability at the interface of the target process, to timely and qualitatively addressed the negative conditions for the implementation of opposing processes of external and internal origin, a rational way to be the formation and implementation of institutional, organizational, resource and technical-technological processes in the composition of their complete group. It is shown that such conditions should be planned and provided at the early stages of the integrated systems life cycle during research to determine the main organizational, technical, system and technological solutions. Organizational and resource processes can be quickly adjusted during operation. Technical and technological processes provided for at the stage of development of the control system do not have wide opportunities for their correction.","PeriodicalId":255578,"journal":{"name":"2020 Systems of Signal Synchronization, Generating and Processing in Telecommunications (SYNCHROINFO)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126562456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
