摘要： In a method of testing a spliced portion of exposed fiber portions of optical fibers, the optical fibers are arranged with each other in line so that ends of the exposed fiber portions are spaced apart from each other by a predetermined distance. The ends of the exposed fiber portions are heated and melted by discharge heating. The optical fibers are then moved in the abutment or closing directions by a predetermined distance, so that the ends of the exposed fiber portions abut against each other to form a spliced portion. The minimum outer diameter value d of the spliced portion is measured. Ratio d/D of minimum value d to value D of the outer diameter of exposed fiber portion is calculated. Spliced portions having splicing defects can be detected by detecting of spliced portions having ratio d/D of less than 1 (d/D

摘要： An apparatus for fusion splicing optical fibers has one rotatable clamp mechanism that is manually operated and a second rotatable clamp mechanism that is operated by a motor. A three position stopper functions in the first position as a stopper against the optical fibers when the optical fibers are moved toward each other and in the second position as a mirror for reflecting an image of respective end faces of the optical fibers. A rapid fine adjustment of the alignment of the polarization maintaining optical fibers can be made.

摘要： In an optical fiber ribbon fusion-splicing device, a TV camera is set such that the horizontal direction of an image sensor contained in the TV camera in which direction a horizontal scanning is carried out and the resolution of the image sensor is higher than that in the vertical direction in which a vertical scanning is carried out is a direction perpendicular to the coaxial direction of a pair of grooved supporting members for supporting fibers of a pair of optical fiber ribbons to be fusion-spliced. Thus, when the fibers of the pair of optical fiber ribbons are set on the supporting members in the coaxial direction thereof, the horizontal direction of the image sensor is perpendicular to the coaxial direction of the fibers of the optical fiber ribbon. Since, therefore, misalignment of the fibers is involved in the high resolution direction, the misalignment can be detected with high precision, without decreasing the power factor of the image sensor.

摘要： In a method of measuring a quantity of heat, the distance between the position of an end of an exposed fiber portion before heating and the position of the end after heating is measured, and the quantity of heat applied to the end of the exposed fiber portion is calculated based on the distance. When heat is applied to an end of an exposed fiber portion, the end is fused and is rounded due to surface tension. For this reason, the position of the end of the exposed fiber portion retracts from the position it occupied before heating by the volume required for rounding the end. This retraction amount corresponds to a quantity of heat applied to the end of the exposed fiber portion. Therefore, by meauring the retraction amount, the quantity of heat applied to the ends of the exposed fiber portion can be quantitatively measured.

摘要： In a method for estimating a splice loss of a spliced portion of a fusion-spliced optical fiber, an amount of axial deviation attained prior to or immediately after heating a pair of optical fibers and an amount of axial deviation attained upon completion of heat treatment on the optical fibers are first detected to provide a difference between the axial deviations, and a splice loss originated from an opposite-phase core distortion is estimated based on the difference between the axial distortions.

摘要： In a method of examining the states of alignment of glass fibers in a pair of ribbon fiber cables by observing their images obtained in two directions, a reflecting mirror is located adjacent to glass fibers of a pair of ribbon fiber cables. Illuminating light is introduced into the glass fibers of the fiber cabes in a direction different from the normal direction of a plane formed by the glass fibers, and an image formed by the illuminating light which is reflected by the reflecting mirror and then passed through the glass fibers and another image formed by the illuminating light which is passed through the glass fibers and then reflected by the reflecting mirror are observed. According to the examining method, the optical axes of two images obtained on the light receiving side can be made parallel to each other to keep the two images extremely near to each other. Therefore, the distance along which the pickup system must be moved can be made short. This makes the system small-sized and the image processing time short. In addition, the objective used in the pickup system, may have a low magnification. Further, all of the glass fibers can be observed once on a screen and the adjustment of focus relative to the glass fibers may be conducted one time when they are observed in each of two directions. Furthermore, their shift from that axis along which they should be aligned can be detected with a higher accuracy.
