Abstract: A device for measuring the parameters of phase elements and dispersion of optical fibers, characterized in that it contains: a light source, serially connected to fiber optic coupler, one of whose arms constitutes a part of the reference arm, and whose second arm constitutes a part of the measurement arm of the device, and a motorized linear stage is mounted on the arm of the device. One of the arms of the device is connected to at least one detector, and at least one collimator is placed in at least of the arms of the device, at least before the phase element. A method of measuring the parameters of the phase element and the dispersion of optical fibers is conducted in two stages, wherein the first stage assumes the calibration of the device and the second stage is the proper measurement.

Abstract: A method of connecting optical fibers coated with conductive layer, preferably metalized, with metal elements, comprising the following stages: 1. preparing the electrolyte, 2. clearing the optical fiber surface and clearing the electrodes, 3. placing the optical fiber and the metal sensor element in the electrolyzer, 4. enabling flow of electricity, 5. cleaning the elements—the optical fiber element bonded to the metal element.
