Abstract
Optical fibers are the basis of data transmission systems. However, during operation, the optical cable may be damaged, and to eliminate the damage that has occurred in the field, it is necessary to know the wavelength of optical radiation in this fiber and the radiation power for each of the wavelengths used. This determines the relevance of developing a method for recording the wavelength of radiation at the output of an optical fiber that is accessible for use in field conditions, without the use of complex and expensive equipment. A method for determining the wavelength of optical radiation propagating through an optical fiber based on the use of the fiber macrobending is proposed. An experimental setup for implementing the method is developed. It is shown that this method can be used for both single-mode and multimode optical fibers. It is established that for all the studied optical fibers, the deviation of the power values determined using the method from the real ones does not exceed 12.5 %. The results of the work can be used in fiber-optic communication systems to determine the wavelength and power of radiation propagating through an optical cable.
