Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0015] Such as figure 1 As shown, the optical fiber hybrid cable of the present invention has a circular cross-section, including an outer coating layer 1 and a cable core 2, and the outer coating layer 1 is made of a low-smoke, halogen-free, flame-retardant polyolefin material with a thickness of 0.5-0.6mm. The diameter of the outer coating layer 1 is 8.2±0.3mm. There is also a shielding layer 3 between the cable core 2 and the outer layer 1, the shielding layer 3 is braided by aluminum-magnesium alloy wire or tinned copper material, wherein the diameter of each aluminum-magnesium alloy wire or tinned copper material is It is 0.12mm and can be braided by 7 strands with a braiding density of 50%, which can not only ensure that the optical fiber hybrid cable has a good performance of shielding external interference, but also can ensure a lower...

Abstract

The invention discloses a hybrid optical fiber cable. The hybrid optical fiber cable comprises a cable core and an outer coating layer, wherein the outer coating layer coats the cable core; the center of the cable core is provided with an optical fiber cable; a plurality of data cables surround around the optical fiber cable; each of the data cables comprises a data cable pair which is formed by intertwisting; a shielding layer formed by weaving aluminum-magnesium alloy wires and a thinned copper material is arranged between the outer coating layer and the cable core; and a data cable shielding layer made of an aluminum foil is coated outside the data cable pair of the data cable. The woven shielding layer of the hybrid optical fiber cable and the data cable shielding layer made of the aluminum foil can effectively prevent internal and external interference of the cable, so that the cable has higher shielding performance; thereof, the optical fiber cable and the data cable can keep respective outstanding performance when transmitting independently; moreover, the optical fiber cable and the data cable are arranged on the same cable, so that convenience is brought to construction, the cost is reduced, and an effect of protecting the optical fiber is also achieved.

Description

technical field [0001] The invention relates to a photoelectric composite cable which can meet the needs of optical fiber communication and ordinary data communication. Background technique [0002] At present, optical cables and cables have been widely used in various fields, but there is a defect in existing optical cables or cables, that is, they can only transmit optical signals or electrical signals respectively. However, in many occasions where optical signals and electrical signals need to be transmitted at the same time, only the respective optical cables and cables can only be connected separately, and corresponding equipment needs to be added at the same time. Therefore, the system is complex and huge, it is not easy to miniaturize and integrate the system, and it also increases a lot of cost. [0003] Therefore, there have been some photoelectric hybrid cables that can transmit optical signals and electrical signals at the same time. At present, domestic Gigabit ...
