ABSTRACT:
A pair of optical fibers each having a core and a plastic clad is connected end to end by removing end portions of the plastic clads to expose end portions of the cores of the fibers, and contacting the end portions of the cores so that the optical axis of one fibers. The contacting portion of the fibers are connected by heat melting. The connecting portion of the fibers are covered with a melting, and covering the connecting portion of the fibers with a protection sleeve composed of an inner plastic layer having a refractive index smaller than that of the core and an outer metal layer and having an inner diameter substantially equal to an outer diameter of the optical fiber. The ends of the sleeve are sealingly connected onto the outer surfaces of the optical fibers, respectively.
