Upgrade of a Composite-Star Optical Network

A splice for two or more electrical wires can be made waterproof by introducing a jelly material into a splice body and splice cover made from an electrically insulating material. The jelly prevents the infiltration of water or moisture into the holes of the closed splice body into which the spliced wires are led. The splice body and cover are formed with a plurality of grooves that correspond to each other such that when the splice cover is closed over the splice body, the grooves form the holes into which the electrical wires are led. The splice cover may be in more than one piece. A conducting material is disposed across the interior of the splice for penetrating the covers on coated electrical wires to effect the splice by creating an electrical contact between the main and branch wires. When the splice cover is closed the waterproof jelly spreads over the outer surfaces of the wires.
