METHOD OF BUILDING A BASIC STATION OF FIBER-ETHER TELECOMMUNICATION SYSTEM OF MOBILE RADIO COMMUNICATION NETWORK Russian patent published in 2017 - IPC H04B10/00 

FIELD: electricity.

SUBSTANCE: central station is connected via an optical splitter with an optical fiber to base stations, the optical radiation from the central station laser is modulated by a radio signal of the forward channel and fed into the optical fiber. The base stations are connected to the optical fiber in series, the modulated optical radiation from the optical fiber is fed to the input of the semiconductor optical amplifier, the modulated optical radiation at the output of the semiconductor optical amplifier is divided into two parts, the first part is introduced into an optical fiber that is connected to another base station, fed to the reflecting element, the reflected optical radiation is fed back to the output of the semiconductor optical amplifier, modulated in a semiconductor optical amplifier received on the radio channel from the subscriber set using the base station antenna by the reverse channel radio signal, at the input of the semiconductor optical amplifier, this modulated reflected optical radiation is divided into two parts, its first part is fed to the base station photodetector, where it is converted into a radio signal, a radio signal of the forward channel is extracted from it, which is transmitted via the radio base station antenna to the subscriber set through the radio base station antenna, and the second part of the modulated reflected optical radiation is supplied to the optical fiber that is connected to the central station at the central station coming from the optical fiber of optical radiation is fed to the photodetector of the central station, in which it is converted into a radio signal, from which the radio signal of the return channel is extracted.

EFFECT: expansion of the field of application.
