Abstract

A core alignment system for aligning a pair of optical fibers to be spliced, in which core alignment is accomplished by applying a pair of aligned beams of light emitted in opposite directions by a semiconductor laser to the butt joint ends of a pair of optical fibers to be spliced, detecting a leakage beam leaking from a side surface of each optical fiber close to the laser, and adjusting the positioning of the optical fibers so that the leakage beams are minimized.
