Performance Characteristics of Fiber Optical Lines and Diagnostic Techniques for Optical Fiber Cable

The paper considers methods for assessing the reliability of FOCL during operation and analyzes methods for diagnosing an optical fiber cable. The main factors affecting the reliability parameters of optical cables and leading to signal losses in optical cables are presented. Reliability indicators are listed. A calculation method for assessing the reliability of digital information transmission is described. The analysis of the calculation of the service life of the optical fiber methods for testing fiber-optic equipment and cables, the procedure for checking an optical fiber, and checking a fiber-optic communication line using an optical time domain reflect meter are shown.
