Abstract
A method of forming a connection between a pair of optical fiber cables, each cable having an optical fiber surrounded by a plurality of protective coverings, in which method the optical fiber of each cable is bared by removing the coverings adjacent the cable ends and the optical fibers are joined by conventional cutting and melting. Thereafter, the space between the ends of the coverings are filled by a moisture impervious coating on the bared fibers, longitudinal non-metallic filaments or filament on the coating, helically wound non-metallic filaments or filament around the longitudinal filament or filaments, the helically wound filament or filaments be covered by an adhesive, and an elastomeric layer, which sets up at temperatures which are low with respect to temperatures used to extrude elastomeric materials, around the helically wound filament. The joint so formed is surrounded by a plastic tube. Also, the joint which is made by such method.
