FIELD: technological processes; communication technology.
SUBSTANCE: invention relates to connecting cables for optical communication lines. Optical coupling contains a tray in the tubular case for mounting cassettes on it with a reserve of lengths and splices of optical fibers, cylindrical tips located in the case, the case is made with flanges at its ends, one of the ends is made with a flange coupled to the flange of the case, and on the second end, there is a cylindrical spacer with a flange joined with the other case flange. In the joints between the surfaces of the flange of the end cap, the spacers and each coupled pair of flanges, there is a sealing gasket, compressed by the coupled flanges, pressed together by a clamp collar enclosing flanges. Protrusion is made on the end part of the tip, and a stop and a groove in which the tip of the tip is located is made on the back of the spacer. Groove is made on the end part of the head, and a protrusion is made on the inner surface of the spacer, which is located in the slot of the head.
EFFECT: reducing the complexity of installation and dismantling.
