Abstract

A solid optical lead formed by a light waveguide having at least two coatings composed of plastic material having an outer layer which is applied directly on the inner layer and is constructed as a flame-retardant layer. The outer layer is constructed as a halogen-free material and comprises an additive that will prevent an adhesion between the outer layer and the inner layer and, thus, assures a good strippability of the outer layer from the inner layer.
