Plastic optical fiber

The optical cable, comprising an of the fibre core (1) and a fibre outer (2) further comprises at least the extra ply: The inner outer layer (3), wherein the thermoviscosity reliably of the optical fibre coating layer and a comprising a polyamide and a 400~6000Pas to of the viscosity compression the fabric and 220℃, zeroAnd the outer shell layer (4), wherein the thermoviscosity of the inner outer layer (3), and stripping force not more than 30N by jointing an inner parts the fabric composed of the following: devicea) 20~95 weights % polyamide, b) 5~45 weights % burning layer, and c) 0~60 weights % impact modifier. The structure tallies current to POF the optical cable industrial claim.
