Problems solved by technology

The optical fiber and copper wire exist independently in the optical cable, so both the optical fiber and copper wire must be covered with a sheath, that is, PBT and PVC, and the sleeve and the wire are then SZ stranded around the central tensile body, so the traditional photoelectric composite cable is large in size. Moreover, the copper wire is not easy to bend, which brings inconvenience to the construction

[0036] Preparation Example of Photoelectric Composite Cable

[0037] The photoelectric composite cable of the present invention includes an outer sheath 3 on the outermost side, a photoelectric composite unit 1 in the middle, and reinforcements 2 arranged on both sides; in this embodiment, there are three photoelectric composite units 1 (the photoelectric composite unit 1 can be selected according to the actual situation). The number of units, one or more all can), and strengthen the house 2 on both sides and form a row.

[0038] Such as figure 2 As shown, the photoelectric composite unit includes a central optical fiber 11 at the center and surrounding optical fibers 13 around the central optical fiber 11 peripheral sides, the outer periphery of the central optical fiber 11 is coated with a graphene layer 12, and between the graphene layer 12 and the surrounding optical fiber 13 and around The outer peripheral side of the optical fiber 13 is fixed with a resin 14 .

Abstract

The invention discloses a photoelectric composite cable. The photoelectric composite cable comprises an outer sheath on the outermost side, a photoelectric composite unit in the middle and reinforcing pieces arranged on the two sides. Specifically, the photoelectric composite unit is prepared by the following method of: (1) coating the periphery of a central optical fiber with a graphene layer; (2) fixing the peripheral side of the central optical fiber coated with the graphene layer prepared in the step (1) around peripheral optical fibers to form a bundle; coating the outer layer of the graphene layer of the central optical fiber and the outer layers of the peripheral optical fibers with resin, and performing curing to obtain a photoelectric composite unit; wherein the number of the peripheral optical fibers is not less than 3.

Description

technical field [0001] The invention relates to a photoelectric composite cable. Background technique [0002] Photoelectric composite cable is suitable for broadband access network system as a transmission line. It is a new type of access method, which integrates optical fiber and power transmission copper wire, and can solve the problems of broadband access, equipment power consumption, and signal transmission. [0003] In the traditional photoelectric composite cable, the optical fiber and copper wire are respectively used as photoelectric composite units to be stranded into a cable core through SZ, and then formed through the sheath process. The optical fiber and copper wire exist independently in the optical cable, so both the optical fiber and copper wire must be covered with a sheath, that is, PBT and PVC, and the sleeve and the wire are then SZ stranded around the central tensile body, so the traditional photoelectric composite cable is large in size. Moreover, the ...
