OPTICAL AND POWER COMPOSITE CABLE

摘要

An optical and power composite cable includes a plurality of power lines adjacently arranged in a cable, each power line having a central conductor and an insulating coating layer surrounding the central conductor; at least one optical fiber unit arranged together with the power lines, each optical fiber unit having at least one optical fiber and a tube surrounding the optical fiber; and a cable sheath surrounding the power lines and the optical fiber unit, wherein, assuming that the thickness of the tube is t and that the outer diameter of the tube is D, the ratio of the thickness of the tube to the outer diameter defined as t/D is 8% to 20%.
