Description

Optical fiber cable

[ technical field ]

The present invention relates to an optical fiber cable.

[ background art ]

With the popularization of 4K televisions, the bandwidth required to be met by the HDMI CABLE is larger and larger, and under the condition of the same specification, compared with a copper CABLE, the HDMI AOC product has the advantages of being longer, thinner, softer, better in signal quality, free of radiation and free of electromagnetic interference, and therefore is widely adopted.

However, when the HDMI AOC cable is subjected to cable drawing at present, an insulation fiber protection wire is added inside the HDMI AOC cable so as to improve the tensile strength of the cable; but the bending resistance of the optical fiber body cannot be improved, and the tensile property improved by the insulation fiber protection wire is limited, so that the optical fiber protection wire has the defects of easy damage property and the like.
