26AWG) represent wire after the completion of conductor cross sectional area size, numerical value is bigger, and sectional area is smaller, and conductor diameter is smaller.Otherwise number
It is worth smaller, sectional area is bigger, and conductor diameter is bigger.
Preferably, the ground wire is tinned wird, the specification of the ground wire is 28AWG.
Preferably, cotton paper clad is provided between the external jacket and the medium line group.
The beneficial effects of the utility model：Fiber-optic signal line group is as transmission signal vector, relative to traditional material or conjunction
Golden conductor effectively reduces the weight of wire rod, simultaneously because the transmission characteristic of optical fiber, the quantity of cored wire reduces half, and external diameter is done
It is smaller than traditional USB3.0 wire rods by 50 percent within 3 millimeters.During signal transmission through fiber, by wire rod both ends photoelectricity
Module is changed, so the electromagnetic-radiation-free in transmission, and strong antijamming capability.

Embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.
As Figure 1-3, a kind of optical fiber USB video/audio wires, including external jacket 6 and in the external jacket 6
Medium line group, the medium line group include fiber-optic signal line group 1, source line group 2 and ground wire 4, the fiber-optic signal line group 1, institute
Source line group 2 and the mutually twisted composition medium line group of the ground wire 4 are stated, the fiber-optic signal line group 1 is used to transmit USB
(Universal Serial Bus, USB) 3.0 audio-video signals.
Fiber-optic signal line group 1 is used as transmission signal vector, and wire rod is effectively reduced relative to traditional material or alloy conductor
Weight, simultaneously because the transmission characteristic of optical fiber, the quantity of cored wire reduces half, and external diameter has been accomplished within 3 millimeters, than tradition
USB3.0 wire rods it is small by 50 percent.Specifically, the proportion of copper material conductor is 8.89, and the proportion of optical fiber is about 1.0, so
The optical fiber USB3.0 data wires overall weight of wire rod this programme of same length can mitigate more than 50 percent.
During signal transmission through fiber, changed by wire rod both ends photoelectricity module, so the electromagnetic-radiation-free in transmission, and
Strong antijamming capability.Wherein two pairs of signal wire making technologies are directly changed to medium line by original strand copper-cored wire-pair twist-band
Group extrusion, a processing procedure is reduced to by four processing procedures, improves production efficiency, while reduced processing procedure and occur extremely, ensure wire rod product
Matter is good.
In the present embodiment, the fiber-optic signal line group 1 include it is middle by 12 and located at it is described it is middle by 12 in two optical fiber
11, the color of two optical fiber 11 is differed to be distinguish between, wherein two optical fiber 11 are used to transmit USB3.0 sounds
Vision signal.
