Аналіз загасання у волоконно-оптичній лінії зв’язку

Abstract

The paper analyzes optic signal attenuation characteristic in such structural components of fiberoptic communication line as optical cable, couplers and end optical crosses. The methods and means of measuring and locating places with high attenuation are considered. It is shown that geometrical parameters deviation of optical fibers leads to attenuation of signals in connectors and welded joints of fiber-optic communication line. Practical recommendations for improving the quality of welded joints and connectors of optical fibers aimed at attenuation in communication line have been formulated.
