Abstract

PURPOSE: To perform branching of light signal without being affected by the mode change of stray light signal by bundling two to more optical fibers whose core sections assume a sector shape of nearly identical radii and fusion-integrating these.
CONSTITUTION: Optical fibers 5, 6, 7 which are formed of cores 1, 2, 3 and clad 4 and whose sections are of the sector shape of nearly identical radii are bundled and are so fusion-integrated that the sections of all the optical fiber cores 1, 2 3 assume the sector shape of the nearly identical radius r requiring one common axis 8 and that the clads 4 of the respective optical fibers exist at the boundaries of these cores 1, 2, 3 whereby the branching and connecting part is formed. The branching and connecting part constituted in this way does not receive the effect of mode change, etc. at the time of branching the signal distributing to the axial symmetry in the optical fibers of the circular section and therefore in the case of branching and monitoring transmission signal levels in a measuring apparatus or the like, the reliability may be improved.
