Narrowband Lengthy Analogue Fiber Optic Communication Line for Telemetry Data Transmission

The necessity of placing sensors for different purposes on power lines is considered. Particular attention is paid to solving environmental control problems with multifunctional complexes using various sensors. The variants of telemetry information transmission over long distances in the presence of different types of interference are considered. The use of fibre-optic lines for transmitting this information using analogue signals was substantiated. The design of analogue fibre-optic communication line for transmitting signals over 500 km without amplification was developed. The calculation of the developed communication line is made. Preliminary experimental researches of parameters of the developed fiber-optic communication line are carried out. Advantages and disadvantages of this method of telemetry information transmission are determined.
