ABSTRACT:
A light waveguide is protected with a protective covering loosely surrounding the waveguide, which covering is constructed of an inside layer and an outside layer. The inside layer is composed of a material selected from a group consisting of polycarbonate, polyether sulfone and polyetherimide while the outside layer is composed of a material selected from a group consisting of polyester, polyether, polyurethane, copolymers of these polymers as well as block polymers of each of these polymers. The selection of these materials with the two layers provides a good connection between the two layers of the covering.
