Abstract

PURPOSE:To make the axial alignment of each core simple and accurate and achieve higher performance of connection work by forming guide holes parallel to a plurality of cores in the lengthwise direction of the clad. CONSTITUTION:Guide holes 3 parallel to a plurality of the cores 1...which are so disposed as to become parallel with each other are formed in the lengthwise direction of the clad 2 integrally overing the cores 1. The guide hole is provided one the central axis or a plurality of holes are disposed in the position equidistant from the central axis of the clad 2, and at an equal angle, e.g., every 120 deg., over the circumferential direction. This enables the axial alignment of the multicores to be accomplished at a breath and accuretly and enables the connection work of these to be made considerably higher in performance.
