Abstract: Non-contact methods of predicting an insertion loss of a test optical fiber connector are disclosed. Light is sent down the at least one optical fiber of the connector in the fundamental mode to emit an output light beam. The output-beam image is captured at different distances from the fiber end faces to define multiple output-beam images each associated with one of the multiple measurement positions. A Gaussian curve is then fitted to the multiple output-beam images to determine a mode field diameter, an offset, and a tilt of the output light beam. A Gaussian field model that incorporates the offset, the tilt, and the mode-field diameter is then used to predict the insertion loss when connecting to a reference optical fiber of a reference optical fiber connector.
