摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of an insertion error of base fibers of coated fibers of a ribbon subjected to leading-out by rectilinearly aligning the front ends of the bare fibers by an aligning member (hereafter designated as the boot). SOLUTION: The front ends of the bare fibers 12 of the coated fiber ribbon 10 subjected to the leading-out are rectilinearly aligned by retaining the portions parted more distant from the front ends by the boot 40. Also, the aligning spaces of the bare fibers 12 of the boot 40 are nearly equalized to the spacings of the fiber holes 32 of the ferrule 30. As a result, the front ends of the bare fibers 12 face the fiber holes 32 and the bare fibers 12 projecting forward from the boot 40 are inserted and fixed into the fiber holes 32 of the ferrule 30 when the boot 40 fixed to the bare fibers 12 is packed into the ferrule 30. The term 'rectilinearly aligned' signifies that the front ends of the bare fibers 12 maintain the prescribed pitch at the parallel spacings without opening or without bending.
