SPECTRAL ANALYSIS OF ATTENUATION IN OPTICAL FIBERS IN THE PROCESS OPERATIONS

Abstract

The article presents a spectral analysis of the transmission coefficient of an optical fiber in the event of short attenuation jumps. In this case, it is assumed that the time function of the additional loss factor is a symmetrical triangular function with the same rise and fall times. It is shown that the spectral loss density is sensitive to the number of attenuation jumps, has a low-frequency character and has a filtering effect on the useful signal. Approaches to the analysis of performance characteristics of fiber-optic transmission systems under specific operating conditions are considered.
