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 S/N enhancer using the magnetostatic wave signal is disclosed. The S/N enhancer comprises a balun coupler for dividing an input signal into a first and second signals having the same power, the second signal having the phase difference of 180 degree with respect to the first signal; a saturation magnetostatic wave filter for receiving the first signal output from the balun coupler, converting that into a magnetostatic wave signal, and converting the magnetostatic wave signal into a signal having a shape of the first signal, wherein a power of the magnetostatic wave signal is saturated if the first signal has a power of equal to or more than that of a noise signal; a linear magnetostatic wave filter for receiving the second signal from the balun coupler, converting that into a magnetostatic wave signal, and converting the magnetostatic wave signal into a signal having a shape of the second signal, wherein the received second signal is converted into the magnetostatic wave signal having an energy linear to a power of the input signal; and a power synthesizer for synthesizing respective signals output from the saturation magnetostatic wave filter and the linear magnetostatic wave filter.

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.
