FUSION APPARATUS FOR JOINING TWO MONOMODE OPTICAL FIBERS Abstract of the Disclosure Fusion splicing apparatus for fusion splicing pairs of single mode optical fibers has a fusion head having two spaced guiding and locating members mounted on hinge members. One hinge member moves a guiding and locating member up and down, the other hinge member moves the other guiding and locating member forward and back. Actuation of the hinge members is by stepping motors and micrometers. The fibers are held in the guiding and locating members by clamping members, one of which can be pivotted to move a holding member at its upper end laterally. The fiber cores can be aligned axially by actuation of the hinge members and the fiber ends can be separated and pushed together by pivotting the pivot clamping member. Light signal input and detecting modules can be positioned either side of the fusion head. Detected light signals can be used to operate the stepping motor to give automatic alignment. Arc electrodes are provided for giving a preclean arc, a softening arc and a fusion arc. - i -
