Abstract: Embodiments of the present invention provide an improved method of determining splice losses of mechanically terminated optical connectors in the field, without the need of terminating both sides of the fiber link. Embodiments of the present invention also provide means for improving the quality of mechanical splices as utilized in pre-polished fiber optic connectors for terminating single-mode and multimode optical fibers in the field.

Abstract: A method for evaluating the optical insertion loss of a mechanical splice joint of two optical fibers with a laser source includes, upon initiation by a user, automatically performing the steps of: checking for ambient light, estimating the level of noise by analyzing an area of a sensor that is not illuminated by external sources and setting a noise threshold, checking self-alignment by taking a foreground image of the joint with the laser source turned on and one with it turned off, subtracting the images to obtain a resultant image, setting all pixels with levels below the noise threshold to zero, selecting a region of interest of the joint, computing a centroid and a width of the resultant image based on the region of interest, estimating a tilt and if the tilt is above a certain threshold, compensating for the tilt, and processing the resultant image.
