Testing and Loss Measurement Techniques in Optical FIBER for Healthy Optical FIBER Communication

摘要

Practically in all kind of communication system, more or less losses are involved To make the system more efficient, it is needed to identify and trace the faults & losses In optical fiber communication, optical time domain reflectometry (OTDR) is a commonly used technique for characterization and fault location of optical fiber transmission systems. It involves measuring the fraction of a probe pulse that is scattered back from a silica fiber. Because of the very small levels of backscatter in single-mode fiber at long wavelengths, very sensitive optical detection is necessary to achieve proper range performance. For uptime and efficient performance of fiber networks requires testing and evaluation at multiple stages. This paper include various testing methods for optical fiber such as continuity test, continuity of splice, splice loss testing, fiber loss testing .fiber quality testing, reflectance of splice and connector testing and loss measurement techniques such assplice loss measurement, detection of fault locations, insertion loss. This paper describesdifferent testing methods and the way to reduce the losses in fiber cable for the healthy communication.
