Abstract
The article presents the results of solving the problem of attenuation of an optical signal in fiber-optic communication lines. Widely used modern technical solutions of intermediate amplification-regenerative nodes of fiber-optic communication lines are described. The advantages and disadvantages of existing intermediate fiber optic amplifiers are presented. The benefits of optoelectronic signal regenerators include a full restoration of the original properties of the optical signal. The optoelectronic regenerator allows to limiting the amount of internal and external optical noise by acceptable values, but increases and increases the cost of building optical fiber connections.Optical signal amplifiers are also used to increase the range of fiber-optic communication lines. The main advantage of intermediate fiber optic amplifiers is their relatively simple design and, consequently, low cost, as well as high cost of losses and power output.The technical function of the developed fiber optic amplifier is to create a signal and power amplifier that is evenly distributed inside the fiber located in the region of the fiber containing the fluorescent additive.The characteristics, functional and structural diagrams of an optical repeater with erbium amplifiersare shown in detail. The design features of the construction and the principle of operation of the erbium amplifier are described.
