Abstract
An optical terminal using a capillary with a central opening or a bore of a selected cross section and having an insertion opening and a coupling opening. The optical terminal has a light-guiding element, e.g., a lens, positioned in front of the coupling opening. Optical fibers having adjusted cross sections along a fitting length are inserted into the bore such that they are wedged inside it, their tips are positioned at the coupling opening and their cores are offset by a specific distance or offset from the optical axis of the light guiding element. A number of fibers including optical and reinforcement fibers can be wedged in the bore in this manner to ensure a specific offset between the cores of the optical fibers and the optical axis. Precise control of the offset between the cores and the optical axis permits one to accurately control an output angle of light beams issuing from the optical fibers and exiting the optical terminal through the light guiding element.
