Since the optical cable, which is an assembly of optical fibers, is installed at a distance of several hundred kilometers or more, the connection and branching of the cable are necessary in the middle. However, since optical fibers made of very small diameters (125㎛) are formed inside the optical cables, it is very difficult to connect the cores of the optical fibers with each other.
