Patent ID: 7397998

Claim:
An optical fiber positioning method comprising steps of: preparing one or a plurality of optical fibers to be aligned in position, an optical fiber holder having an optical fiber holding hole corresponding to each optical fiber to be aligned in position, and a positioning plate having a fitting hole formed on one principal surface of the positioning plate and fitting therein one end face of the optical fiber holder and an optical fiber positioning hole formed through a bottom of the fitting hole corresponding to each optical fiber holding hole of the optical fiber holder, a predetermined position of each optical fiber positioning hole relative to an outer periphery of the optical fiber holder being defined as an abutting position of each optical fiber; fitting one end face of the optical fiber holder in the fitting hole and inserting each optical fiber into a corresponding optical fiber holding hole of the optical fiber holder and a corresponding optical fiber positioning hole of the optical fiber positioning plate; in a state that the end face of the optical fiber holder is fitted in the fitting hole and each optical fiber is inserted into a corresponding optical fiber holding hole of the optical fiber holder and a corresponding optical fiber positioning hole of the optical fiber positioning plate, abutting each optical fiber on the abutting position of a corresponding optical fiber positioning hole of the optical fiber positioning plate; and in a state that each optical fiber is abutted on with the abutting position of a corresponding optical fiber positioning hole of the optical fiber positioning plate, fixing each optical fiber to the optical fiber positioning plate.
