In content of the present utility model: described insulating barrier (3) is preferably the cross-linked polyolefin insulating barrier, and the main manufacturing enterprise of cross-linked polyolefin has Shanghai Sirui PolymerTechnology Co., Ltd., Ka Ante to plastify (Xiamen) Co., Ltd, Wuxi high polymer Co., Ltd of love nation.
In content of the present utility model: described optical fiber is optical fiber, is the fiber that a kind of glass or plastics are made, and is prior art.
Compared with prior art, the utlity model has following characteristics and beneficial effect:
(1) adopt the utility model, adopt a plastic fiber outer cladding layer of metal to make the structure of transport vehicle, both satisfied the transmission of the signal of telecommunication, realized again the transmission of light signal, greatly reduce simultaneously product weight;
(2) the utility model adopts cross-linked polyolefin to make insulating material, has not only satisfied insulation property but also alleviated product weight, has improved the product energy of anti-the ambient adaptability;
(3) adopt the utility model, mobile occasion realizes light signal and electrical signal communication transmission in the open air, makes light transmission and the electrical transmission dual-use function that rolls into one; And the signal of telecommunication and optical signals are very large in frequency phase-difference, interactional phenomenon can't occur; Have not changing under existing separate type broadcasting system, realize light, electric compound signal transmission, reduced system's repeated construction and caused a large amount of inputs.Simultaneously, after photoelectricity is compound, make system configuration simple, interface plug reduces through compound quantity, is convenient to artificial fast operating; In addition, do not change the product structure size, alleviated again product weight, so that motor-driven quickly retracting operation is convenient in the more existing wiring dish tool of good utilisation and the compatible use of portable instrument;
(4) the utility model product preparation process is simple, and cost is low, and as telephone or " wire communication transmission equipment " matching used special-purpose insulate line in wired communication system, the product external diameter is not more than 3.0 ㎜, and is practical.
