PURPOSE:To execute easily and with high accuracy positioning of an optical fiber strand by inserting a tapered part of a core which is bundled in a fixed shape and is subjected to heating wire-drawing, into a small diameter hole of a connector, forming them as one body by an adhesive, and thereafter, polishing the end face. CONSTITUTION:Exposed strands 3 of plural optical fiber cores 1 are made to pass through a heat contacting tube 8, are set temporarily, and the smallest diameter part of a tapered part formed by heating, elongating and wire-diawing them is cut, and is inserted into a positioning hole 7 of a connector body 6. By feeding the core 1 until the tapered part 11 of the strand 3 projects from the tip of the hole 7, a diameter of the hole 7 can be set so that a gap between the hole 7 and the strand 3 becomes minimum, and the positioning accuracy of the strand can be made very high. Subsequently, the connector 6 and the core 1 is formed as one body by an adhesive, and the end face is polished, by which the connector is finished. Accordingly, a connection loss can be made extremely small. |
