The invention discloses an optical fiber equipped transmission cable which comprises an oversheath that packages the surface of an aramid fiber layer. Furthermore the aramid fiber layer is internally provided with a heat insulation layer. The heat insulation layer packages the surface of an inner protective layer. The inner protective layer packages the surface of a water blocking layer. The inner center of the water blocking layer is provided with a central reinforcing member. A buffer tube in the water blocking layer is uniformly arranged at the periphery of the central reinforcing member. Optical fibers are uniformly arranged in the buffer tube. The optical fiber equipped transmission cable does not contain any metal material and has a total insulation structure and a relatively high voltage resistance index. The optical fiber equipped transmission cable has advantages of facilitating arrangement and construction on an overhead electric power line in live operation, realizing no effect on operation of the line, realizing a capability of bearing relatively high tension by means of the aramid fiber material with high tensile strength, satisfying a requirement for large span of the overhead electric power line, preventing unfirmly closing and artificial gunshot, realizing relatively low thermal expansion coefficient, ensuring small radian change of the cable when large temperature change occurs, realizing small weight and obtaining low icing risk and low wind load.
