Abstract: A rotation and alignment device for assembling of an optical fiber connector with a lower connection loss. This device image-processes the distribution of optical intensity of light emitted from an end surface of an optical fiber of a ferrule and derives an optical peak intensity point of the end surface of the optical fiber such that the point is placed in a predetermined region of a rectangular coordinate system. This device comprises a rotation and marking part for controlling a rotational position of a marker with respect to the ferrule and marking the optical peak intensity point on an outer surface of the ferrule. A ferrule fixture part is coupled to the rotation and marking part and fixes the ferrule such that the outer surface of the ferrule is marked with the optical peak intensity point by the marker. A vertical supporting part supports the rotation and marking part and the ferrule fixture pat. An optical system and fiber alignment part is mounted on the support rail part and magnifies and aligns the end surface of the optical fiber of the ferrule. The support rail part assures the rotation and marking part and the optical system and alignment part of a desired horizontal location.

Abstract: A multi-fibre connector for connecting an optical cable and a transmitter consists of an adapter (10) with orifices (12) into which a male component is inserted, a through passage and holes (11) in its upper and lower walls for an engaging element (23). The male component (20) has a through channel for the optical fibres and an end tip with a series of small holes for the optical fibre cores, providing protection and alignment. The connector incorporates protectors (30) for the optical cable, designed to surround its outer ends and protect it from breaking, while an inner sleeve (40) of triangular cross-section ensures alignment of the tip (25), which is made from a composition material of epoxy resin and carbon fibres. The carbon fibres are 0.7-0.9 mm long and comprise 25-35% of its weight.

Abstract: A single core optical fiber connector is disclosed in which an optical signal transmitting line between optical fibers is maintained or short-circuited with a low power loss by utilizing a sectional contact of a single core optical fiber. An elastic deformation energy of a polymer material is utilized so as to achieve the sectional contact for minimizing the loss, and precisely machined alignment devices are utilized so as to reduce the misalignment between the optical fibers, thereby improving the assemblability and the economy. The optical fiber sections which are lightly ground on a grinding paper are contacted by using a precisely machined alignment device and by utilizing the elastic deformation energy of the elastic ferrule. This contact is maintained by a coupling between a specially designed plug and an adaptor, thereby forming a structure of an optical fiber connector and an alignment device. The ferrule, the alignment device and the coupling structure which are the critical factors for the optical fiber connector are provided in the form of a new material, a new technique and a new structure. Consequently, the economy, the performance and the assemblability are improved, thereby contributing to the early settlement of the fiber optics system.
