[0032] Reference Figures 3 and 4The outside of the isolation layer 5 is fixedly connected to a protective component for nearby support and protection of the optical cable. The protective component includes an insulating layer 10. The insulating layer 10 is made of alkane. Alkanes have good electrical insulation, high resistivity, and are non-conductive.
