  • Patent number: 10564375
    Abstract: An optical and electrical composite multimedia cable including: an optical unit including a plurality of optical fibers and an optical-fiber protective layer, the optical-fiber protective layer formed by filling gaps between the optical fibers with curable resin and covering outer sides of the optical fibers with the curable resin and then curing the curable resin; a plurality of conductor units each including a conductor and an insulator covering the conductor; and an outer jacket provided around the optical unit and the conductor units.
    Type: Grant
    Filed: June 11, 2015
    Date of Patent: February 18, 2020
    Assignee: LS CABLE & SYSTEM LTD.

  • Patent number: 8861911
    Abstract: 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%.
