ABSTRACT:
A terminal for an optical transmission cable, e.g., formed of a central optical fiber surrounded by a heat-deformable plastic coating, comprises a metallic body portion with an axial bore having a relatively small, fiber receiving aperture, an expanding tapered portion, and a cylindrical portion. A heat insulative sleeve is disposed about the bore end at the optical cable receiving face of the terminal.
To affix the terminal to a cable end, the terminal body is heated, and the cable axially urged through the bore. The heated terminal body deforms the cable coating, locking the cable into place with the fiber projecting through the relatively small bore aperture, when the assembly cools. The insulative sleeve prevents cable deformation and attendant spurious optical misalignment about the end of the terminal by there separating the cable coating and the heated terminal body.
Two terminated optical transmission cable segments may be connected by simply inserting the two terminal body members within an outer sleeve.
