Abstract

This work presents fast and simple method for estimation of the insertion loss at the connection of two singlemode optical fibers with contaminated fiber optic connector ferrule end faces. Proposed solution is based on the fundamental mode coupling coefficient (or e.g. transmission coefficient) evaluation via discretized mode field overlap integral. It is represented in the form of nested sums on radial mode field distributions, which are described well by Gaussian function under weakly guiding approximation or may be taken from the mode field distribution matrix, computed by rigorous numerical methods during analysis of real optical fiber samples with nonsymmetrical geometry. Proposed approach provides ability of taking into account the mode field distortions, occurring due to 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.
