Method for Estimation of Reflection on Fiber Optic Connection Based on Analysis of Images of End Surfaces of Ferrule Connectors
- Abstract: This work presents an alternative method for evaluating the reflection coefficient at a detachable connection of single-mode optical fibers based on the results of the analysis of images of the contaminated end surface of the ferrule of a pair of connectors of the studied joint, obtained with a standard field set of video diagnostics of the state of fiber-optic connectors. The results of experimental verification of the proposed method are presented, which have demonstrated the potential of its use in practical applications of "contactless" determination of the reflection coefficient on a fiber-optic connector.
