A kind of optical hybrid cable

Abstract

The invention discloses a photoelectric hybrid cable, comprising: a hybrid cable core piece and a transparent flame-retardant self-adhesive coating layer, the hybrid cable core piece includes a plurality of optical fibers, a transparent second sheath and a supporting frame, and multiple The first optical fiber is fixed in the supporting frame; the flame-retardant self-adhesive coating layer is wrapped on the outer surface of the hybrid cable core; The arched self-adhesive coating glue part is formed; the bow belly of the self-adhesive coating glue part is equipped with off-white conductive wire harness, and the outer surface of the conductive wire bundle is wrapped with a transparent first sheath; the inside of the conductive wire bundle There is a strip-shaped gas capsule filled with nitrogen gas; the strip-shaped gas capsule is pressed against the conductive wire bundle on one side and the hybrid cable core piece on the other side. The invention improves the tensile ability of the invisible photoelectric hybrid cable, and the gas capsule is arranged between the first sheath and the second sheath, which improves the overall bending resistance; and ensures that it can be effectively integrated into the background color of the environment.

Description

technical field [0001] The invention relates to the field of optical cable production, in particular to a photoelectric hybrid cable. Background technique [0002] The existing invisible optical cable is basically a single optical fiber coated with transparent self-adhesive coating glue, which has the disadvantages of poor tensile strength, bending resistance, and poor flame retardancy; moreover, it can only transmit optical signals and has a single function . Contents of the invention [0003] Aiming at the above problems, the present invention proposes a photoelectric hybrid cable, which solves the disadvantages of the existing invisible optical cable, such as poor tensile strength, poor bending resistance, and poor flame retardancy, and can only transmit optical signals and has a single function. [0004] The technical scheme that the present invention takes is as follows: [0005] A photoelectric hybrid cable, comprising: a circular hybrid cable core and a transparen...
