Abstract

PURPOSE:To achieve the improvement in the bonding accuracy and working efficiency of the multicore optical fibers by opposedly providing V-grooves of 60 deg. in the angle of bottom faces, stacking and butting the fibers of an equal outside diameter in each V-groove and integrally fusion-connecting the same. CONSTITUTION:V-grooves 12 opposing to each other and cross grooves 14 intersecting orthogonally therewith are provided on the top surface of a V-groove guide 10 and electrodes 16 are provided in the cross grooves 14. The angle of the bottom face of the V-grooves 12 is made 60 deg.. Fibers 100 of an equal outside diameter having been removed of clads from the core wires are piled in the V-grooves 12 and are retained frm above with fiber retainers 18. Then, the fibers 100 circumscribe with each other and stand in a form of an equilateral triangle and the positions of cores 102 are determined. With the ends of the respective optical fibers 100 being aligned, they are butted simultaneously and all the fibers 100 are integrally fusion-bonded by electrodes 16. In this way, the multicore optical fibers may be integrally bonded with good accuracy and efficiency.
