▎ 摘　　要

NOVELTY - The transmission line has a guide graphene lead symmetrically distributed in a surface of a pollute protecting coating layer i.e. polyimide layer. A graphene guide is filled with a polyimide insulation material during spraying process. A protective layer is covered on a surface of the graphene lead. Thickness of the pollute protecting coating layer is 10-50 microns. Thickness of the graphite lead is 1-100 nm. The graphene lead is connected to a graphene material plate by pressing the pollute protecting coating layer. USE - Photoelectric dual-guide transmission line. ADVANTAGE - The graphene lead is utilized as an electric signal lead that is formed in a fiber surface, thus avoiding optical and electric signal lead binding of the transmission line. The transmission line can satisfy transmitting network construction requirement in a convenient manner. DESCRIPTION OF DRAWING(S) - The drawing shows a cross sectional view of a photoelectric dual-guide transmission line.
