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.
Claims18
A solid optical lead comprising a light waveguide having at least one inner layer of plastic material and an outer layer of plastic material applied directly on the inner layer, said outer layer being a flame-retardant layer constructed of a halogen-free material and the outer layer having an additive to the material of the outer layer to prevent an adhesion between the inner layer and the outer layer and to provide a good strippability of the outer layer from the inner layer, said additive being a halogen-free material.
A solid optical lead comprising a light waveguide having at least one inner layer of plastic material and an outer layer of plastic material applied directly on the inner layer, said outer layer being a flame-retardant layer constructed of a halogen-free material and the halogen-free material of the outer layer having a halogen-free additive mixed therein to prevent an adhesion between the inner layer and the outer layer and to provide a good strippability of the outer layer from the inner layer.
