Abstract

This work presents fast and simple method for estimation of the reflection at the connection of two singlemode optical fibers with contaminated fiber optic connector ferrule end faces via results of analysis of connector ferrule end face photo-image. Proposed solution is based on discretization of mode field distribution and following passage to representation of the mode field overlap integral in the form of finite nested sums. Proposed approach provides ability of taking into account the mode field distortions, occurring due to the optical fiber end face contaminations, by directly overlapping of connector ferrule end face image over discretized mode field radial distribution. We present some results of developed method approbation on really measured fiber optic connections between standard singlemode optical fibers with various order contaminated ferrules.
