    In a method for fixing an optical fibre in an optical fibre connector element the fibre is fixed therein by means of centering elements (22) and a curable material (28), for example an adhesive. The centering elements and the curable material are positioned between the envelope of an end portion of the optical fibre (6) and a surface portion (26) of the connector element surrounding said envelope. After the fixing of the fibre end portion in the connector element the end portion of the connector element including the centering elements (22) and the fibre end portion (6) are machined, for example ground, up to a plane (30) which is positioned inside the points of contact between the centering elements (22) and the fibre end portion (6) and between the centering elements (22) and the surface portion (26) of the connector element surrounding the fibre end portion.

    about
    The invention relates to the field of optical fiber technology, in particular, to a method of installing a fiber-optic fiber in the tip of a fiber-optical fiber connector.
    The aim of the invention is to prevent the transmission of voltage to an optical fiber,
    Figure 1 shows the connector tip assembled with the optical fiber before removing the end portion; Fig. 2 is the same after removal of the end portion.
    The fiber light guide 1 (Fig. 1), from the end part 2 of which the protective sheath 3 has been removed, is placed inside the long tip A so that the bare part 2 of the light guide passes freely between the three balls 5. The tip 4 consists of two bushings 6 and 7, coaxially connected along the thread 8, and the sleeve 7 has coaxial inner 9 and outer 10 conical surfaces. Moving the sleeve 7 along the thread 8 and pressing the balls 5 with the inner conical surface 9 to the end 11 of the sleeve 6, install three balls 5 until they touch the bare part 2 of the light guide 1, thereby centering the fiber light guide 1 relative to the outer conical surface 10. Adhesive 12 is inserted into the cavity 13 of the tip 4 from the side of the balls 5 and attach part 2 of the optical fiber 1 to the tip 4 Epoxy or curing with 1 glue light is chosen as adhesive 12.
    To simplify the technology, the balls 5 are made of a transparent material (glass), and the curing of the adhesive 12 is carried out with light.
    After the adhesive 12 has hardened, the end part on the end 4, with fiber 1, is ground to a flat surface ;: 14, remove the material over a length exceeding the distance from the tip of the tip 4 to the point of contact of the balls 5 with the optical fiber 1 by

    no greater than the radius of the ball 5. This removes the end part of the rake 4 of the fiber light guide I deformed by the centering balls 5 and, consequently, eliminates the reason for the formation of possible mechanical defects - the stressed state of the fiber light fiber
    In the grinding process, the end portion of the tip 4 is formed perpendicular to the axis of the optical fiber 1 (Fig. 2), and then polished.
    The outer conical surface 10 serves as a mounting surface when two tips 4 are connected in a detachable connector (not shown).
