Abstract
The article provides a brief analysis of the condition of the National transport network NISM (national information superhighway) based on fiber-optic communication lines, where work is being carried out on the construction of the DWDM backbone network (Dense Wavelength Division Multiplexing), increasing the power of external Internet channels, expanding the installed capacity of the DWDM backbone network equipment, ensuring traffic protection, and building a fiber-optic network to connect new corporate clients. The article also provides information about the state Program «Digital Kazakhstan», which aims to accelerate economic development and improve the quality of life of the population through the use of modern digital technologies in the future and create a digital economy of the future in the long term. Brief information on the draft program for the introduction of broadband Internet access for SNP was provided (Rural localities), where the basis for the implementation of this program is the FOCL. The features of the fiber-optic cable where the main element is the optical fiber (OF), are reflected. OF is currently considered the most advanced medium for transmitting information, which allows you to transfer large flows of information over long distances without additional costs. Attention is paid to the issues of designing the FOL, which consists of several stages and documents. Also, attention is paid to the problems in the design of the FOCL. In order to reduce the time of development of projects on FOCL, it is recommended to use electronic tools, among which we can highlight the program «Calculation of self-supporting cables» of Incab. At the end of the article, information about the methods of construction of the FOCL is briefly given, as well as a description of the experiment, the results of the study and the conclusion. Subject of research. The subject of the article is modern methods of design and construction of fiber optic systems. Purpose of work. To consider modern methods of design and construction of FOCL on the example of the city of Almaty (a suburban area with a complex mountain terrain). Methodology and methods. The research is based on the analysis of the National superhighway, the «Digital Kazakhstan» Program, as well as the program for the introduction of broadband Internet access for rural localities, which is based on the FOCL. A brief analysis of the transport network of communication (telecommunications) in the territory of Almaty with different types of technologies such as PDH, SDH and gradually introduced new technology DWDM.
Keywords: FOCL, National superhighway, broadband, Internet, rural settlement, PDH, SDH, DWDM, transport communication networks (telecommunications), fiber optic cable, design methods, electronic tools for designing FOCL, construction methods.
