The article is devoted to the issues of metrological support of optical communication. It shows the types of connectors and options for completing couplings for long-distance optical cables that can introduce their own attenuations into the data transmission network not exceeding those established by existing standards in the field of telecommunications. Various methods of measuring the parameters of optical fibers and passive components at various stages of construction and operation of fiber-optic communication lines are presented. Theoretical and practical issues related to the transmission of light through optical fibers are analyzed. The main transfer characteristics of a multimode optical fiber and nonlinear effects arising in an optical fiber during signal transmission over passive optical components are presented [1]. The obtained results of metrological measurements corroborate the existing technical solutions for creating a centralized optical architecture of structured cable systems and for improving the quality of optical communications. Certain obtained figures will make it possible to carry out work on the design and installation of a physical infocommunication infrastructure, which includes the following functional subsystems: vertical subsystem, active network equipment system, horizontal subsystem, and workplace system. The presented calculations show that multimode fibers optimized for laser radiation have minimum values of intermode and chromatic dispersions, and further development of the physical layer of the ISO OSI infocommunication network model will allow a complete transition to these types of fiber-optic systems with a higher bandwidth ratio.
