ABOUT BEAUTY, TECHNICAL PERFECTION AND SWITCHING METHODS The expediency of using methods of packet switching and circuit switching in telecommunication networks is discussed, as well as the criteria used for their evaluation. In particular, their effectiveness for different types of traffic and security are considered. The paper also traces the evolution of switching methods and explains the reasons for the emergence and widespread use of the All-over-IP concept.

TECHNOLOGY OF PASSIVE OPTICAL LOCAL AREA NETWORKS Considered are the main features, advantages and disadvantages of passive optical networks. It is shown that this technology is a natural development and a successful way to use the well-known advantages of fiber-optic technology at the lower levels of information systems, where it can potentially compete with classical twisted pair solutions. The greatest benefits are achieved in networks with a centralized architecture.

WIRED BBA: SUNSET AFTER DAWN? Some twenty years ago, B2C broadband market participants dreamed of optics at least at home, and the market itself developed mainly where there was the biggest money - that is, in B2B. Wireless access with the first IEEE 802.11 networks was not yet a competitor to anyone, and data transmission over GSM networks was not even a “dial-up” telephone access.

OPTICAL ROUTE IN THE TRANSPORT IMT-2020 / 5G NETWORK The issues of routing in the IMT-2020 / 5G transport network, as well as the hardware and software complex of equipment for the Backhaul segment and requirements for it are considered. Taking into account the need to form end-to-end connections in the 5G network, a method is proposed for constructing the optimal route at the optical level with a two-parameter metric and weighting coefficients for each parameter, which can be determined by the 5G scenario. The most important characteristics of the IMT-2020 / 5G network are recommended as criteria: delay and optical signal-to-noise ratio (OSNR).

QUALITY OF LAN CABLES - THE BASIS FOR RELIABLE WORK OF SCS AND BBA NETWORKS The quality of LAN cables is largely determined by the uniformity of the insulated copper core. The estimation of the working capacity of the twisted pair, which is taken as the main parameter in the system of automatic regulation of the linear capacity and the diameter of the insulated core was discussed. Practical recommendations are formulated to ensure high uniformity of cables when insulating a copper core.
