DEVELOPMENT OF MODEMS FOR ATMOSPHERIC OPTICAL COMMUNICATION LINES Since 1960, when a laser was developed, numerous experiments on the use of atmospheric optical communication lines (AOCL) have been conducted throughout the world. Progressively photodiodes have become better and nowadays the positive assessment of AOCL usage is supported by experiments on organizing of the communication between aircraft and tests of AOCL for satellite communication.

Development of FREEBSD operating system image for installing a virtual router and routing path switching software The pressing problem of the IT departments of many modern enterprises is the lack of server resources to process the necessary information. The article proposes to virtualize the server in order to increase its functionality. The scientific novelty consists in analyzing existing virtualization solutions, choosing a virtual platform and developing software for efficiently transferring the entire enterprise system to it without loss of time and data. Practical novelty consists in the development of software for automatic switching of routing paths written in Perl.

Peculiarities of overhead fiber optic cables mounting at low temperatures It is observed that the optical fiber bending radius on the cable fitting port outlet of the mounted sleeve decreased by the decreasing of temperature.
Presented are the results of the study of radii on the cable fitting port outlets for different types of cable makeups depending on background temperature and dependencies of cable fitting port outlets bending radii on the cable rigidity.

Robot cars go out in people The market of unmanned vehicles is very young and is still virtually without rights because of the inevitable lag of the legislative base from technology. However, the enormous prospects for its development in the coming years are no longer in any doubt. As in the rest of the world, decisive steps are being taken in Russia to approach the unmanned future of motor transport.

Dual-channel PWM based on LE with charge protection on timing capacitor the action of sawtooth voltage The pulse width modulator (PWE) is an inherent part of any secondary pulse power supply. Observed are the PWM circuits based on principles of double controlling influence on a ramp of sawtooth voltage operating in a such moment in timing capacitor when the voltage formed on a timing capacitor stays equal to the switching threshold
of the logical element (LE).

Alexander S.Popov: triumph and tragedy of the scientist. Part 2 In March-April 2019, in connection with the 160th anniversary of the inventor of radio, in the Popov Central Museum of Communications, the exhibition "The triumph and tragedy of the scientist" was held. Alexander S. Popov did not really see his triumph, and the tragic collisions of the beginning of the 20th century, especially in 1905, ended for him with a premature departure from life.
