The most commonly used speed converter is a weather vane converter mounted on a weather vane. Provides an electrical signal about the direction of the wind using a rheostat or an electronic converter. The converter system is visible as a thermal quadrupole.

the fact that most of the data around the world is transmitted over the network, the growing demand for online services requires improving the reliability of the network, placing more responsibility on industry personnel. To solve the above problems, building computer networks from fiberglass-optical cables is the most effective solution today.

New applications of AFN elements of narrow-band semiconductor materials are considered. The physical and technical foundations of photoelectronic converters of deflecting systems and optical modulators based on AFN elements are analyzed.
