Title: Automatic optimization of a splice loss estimator for optical fiber splicers

Abstract: A technique is provided for automatic optimization of a splice loss estimator of a fiber splicer (1), where the splice loss estimator is adapted, in a splice loss estimation procedure, to estimate the splice losses (L.sub.ti) of splices (i) of optical fibers as produced by the fiber splicer from images taken of the optical fibers at the splicing thereof, and the splice loss estimation procedure includes the use of splice loss estimation parameters (P.sub.j). The estimator estimates splice losses based on information (C.sub.ij) obtained from the images and the estimation parameters. Further, the splice losses are measured by means of a measurement instrument (3). The estimated (L.sub.ti) and measured (L.sub.Mi) splice losses, and the information obtained from the images are uploaded (71) into an off-line computer (5) and the key estimation parameters are automatically optimized by the selection of any solution within the Bellcore accuracy criteria (75), whereafter the optimized estimation parameters are downloaded (81) to the splicer.
