Abstract
An apparatus for aligning the centers of the cores of two optical fibers prior to their being fused together for splicing. A pair of supporting members are provided, each of which has a V-shaped recess in which an end of a respective one of the optical fibers is fixed. The supporting members are movable relative to one another in a direction substantially perpendicular to the axial direction of the optical fibers. A transparent light conducting member forms a bottom portion of the recess of at least one of the supporting members. A photodetector is optically coupled to the light conducting member.
