PURPOSE:To perform end positioning at the measuring of the transmission characteristics of multiple optical fibers rapidly and accurately by supporting the plural optical fibers parallel to the fulcrum shaft on a cylinder equidistant from the revolving fulcrum shaft. CONSTITUTION:The V-grooves 14a, 14b... provided at an equal interval corresponding to the revolving pitch, etc. of a standard pulse motor on the circumference of a V-grooved cylindrical body 14 are constituted equidistant from a revolving shaft 15 and parallel to the shaft 15. Hence, if multiple optical fiber strands are supported in these grooves 14a... and their positions in the axial direction only are adjusted, the end positioning of the multiple optical fibers at the measurement of their transmission characteristics is accomplished rapidly and accurately. Here, if a cylindrical body 24 which uses parallel plane glass 26 as its bottom and is filled with glycerol or the like of the same refractive index as that of the optical fibers is used, the ends of the optical fibers 1... are positioned without making adjustment in the axial line direction. |
