Description
Technical field
The present invention relates to a kind of broad band photoelectrical hybrid cable, it is non-shielding six class copper cables (UTP Cat.6) or non-shielding seven class copper cables (UTP Cat.7) and the cable that mixes of optical cable, the transmitting optical signal and the signal of telecommunication simultaneously.
Background technology
Along with the continuous development of information communication, users increase fast to the demand of information, such as the multimedia communication that utilizes computer, video telephone and video conferencing etc.At present, the user realizes broadband access mainly still by the copper cable twisted-pair feeder, but the limitation of its transmission capacity exposes, and therefore, jumbo Fiber to the home is only the inevitable choice of following broadband service.But at present the compatibility and the cost of the price of optical fiber and the terminal equipment that matches thereof are still high, and making whole realizations Fiber to the home also needs one period time.Therefore, believe in a very long time, when building connects up, need optical fiber and copper cable twisted-pair feeder cloth is all selected to use for people in the future.
For adapting to this situation, broad band photoelectrical hybrid cable has just appearred on the market.Comprise an oversheath on the structure of existing broad band photoelectrical hybrid cable, be set side by side with optical cable and copper cable in the oversheath, optical cable is made of optical fiber and sheath, and copper cable is common five class copper cables, six class copper cables or seven class copper cables on the market now, with non-shielding six class copper cables (UTP Cat.6) is example, it comprises sheath, four pairs of pair twist electric wires is set in the sheath and separates the crossing skeleton that four pairs of knots twist electric wires.Generally speaking, existing broad band photoelectrical hybrid cable is exactly separate optical cable and in aggregates the forming of copper cable parcel that directly will place side by side with an oversheath, be to carry out existing optical cable and copper cable simple and put stack, not with both organic combinations, therefore exist sheath to repeat to be provided with that consumptive material is many, overall volume takies the defective more than the wiring space greatly.
Summary of the invention
The present invention is for solving really optical fiber and copper cable organically not being combined as a whole of existing broad band photoelectrical hybrid cable existence, sheath repeats to be provided with, many, the bulky problems of consumptive material, provide a kind of and really optical fiber and copper cable are organically combined broad band photoelectrical hybrid cable simple in structure again, that cost is low.
For achieving the above object, the technical solution used in the present invention is: a kind of non-screening broad band photoelectrical hybrid cable, comprise non-shielding six classes or seven class copper cables, these non-shielding six classes or seven class copper cables comprise an oversheath, the crossing skeleton that is provided with four pairs of pair twist electric wires in the oversheath and separates four pairs of pair twist electric wires, every pair twist electric wire all is made of the core outsourcing insulation; Its innovative point is: the center of described crossing skeleton offers a centre bore along axis, is equipped with optical fiber or fibre core in this centre bore.
Related content in the technique scheme is explained as follows:
1, in the such scheme, described " being equipped with optical fiber or fibre core in the centre bore " is meant the optical fiber that can penetrate one or more in the centre bore, perhaps directly penetrates naked fibre core.Because the crossing skeleton has here played the protective action of fiber cladding, therefore can directly wear naked fibre core at centre bore.
The quantity of described optical fiber and fibre core is not limit, and can be one or more, by the instructions for use setting.
2, in the such scheme, described crossing skeleton, insulating barrier and oversheath all adopt fluoroplastics, make broad band photoelectrical hybrid cable integral body not combustion-supporting, do not burn yet, can continuous operation under 200 ℃～250 ℃ high temperature.
3, in the such scheme, described " non-shielding six classes or seven class copper cables " promptly are meant existing standard and non-shielding six class cables (UTP Cat.6) and non-shielding seven class cables (UTP Cat.7) on the market.
Design principle of the present invention is: the present invention is at the center drilling of the crossing skeleton of existing non-shielding six classes or seven class copper cables, in the hole, place optical fiber, be about to non-shielding six classes or seven class copper cables and be transformed into broad band photoelectrical hybrid cable dexterously, make this cable transmitting optical signal and the signal of telecommunication simultaneously, and the experiment proved that the light signal and the signal of telecommunication do not disturb mutually in transmission, functional.And because of optical fiber is arranged on the crossing skeleton center, crossing skeleton becomes the overcoat of optical fiber naturally, and optical fiber is played booster action.
Because the technique scheme utilization, the present invention compared with prior art has following advantage:
1, because the present invention adopts the crossing skeleton center of non-shielding six classes or seven class copper cables to add the structure of optical fiber, energy is the transmitting optical signal and the signal of telecommunication simultaneously, and the experiment proved that the light signal and the signal of telecommunication do not disturb in transmission mutually, and is functional.
2, equally because the present invention adopts the crossing skeleton center of non-shielding six classes or seven class copper cables to add the structure of optical fiber, simply, saved the sheath and the reinforcement material of optical fiber on the structure, consumptive material is few, and cost is low.
3, same because the present invention adopts the crossing skeleton center of non-shielding six classes or seven class copper cables to add the structure of optical fiber, and overall volume is equal to general non-shielding six classes or seven class copper cables substantially, and wiring occupies little space, it is more convenient to connect up.
4, because oversheath, crossing skeleton and insulating barrier among the present invention all adopt fluoroplastics, integral body of the present invention is not combustion-supporting, do not burn yet, and oxygen index 〉=95 can continuous operation under 200 ℃～250 ℃ high temperature.
