Description

Optoelectronic broadband shielding mixed cable

Technical field

The utility model relates to a kind of broad band photoelectrical hybrid cable, and it is shielding six class copper cables (STP Cat.6) or the cable that mixes that shields seven class copper cables (STP Cat.7) and optical cable, can the while transmitting optical signal and the signal of telecommunication.

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, photoelectricity mixing cable has just appearred on the market.Comprise an oversheath on the structure of existing photoelectricity mixing 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, to shield six class copper cables (STP Cat.6) is example, and it comprises four pairs of pair twist electric wires, separates the crossing skeleton of four pairs of pair twist electric wires and from inside to outside is wrapped in its outside screen and sheath successively.Generally speaking, existing photoelectricity mixing 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, consumptive material is many, overall volume is big, take the defective more than the wiring space.

Summary of the invention

The utility model is for solving really optical fiber and copper cable organically not being combined as a whole of existing photoelectricity mixing 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 photoelectricity mixing cable simple in structure again, that cost is low.

For achieving the above object, the technical solution adopted in the utility model is: a kind of optoelectronic broadband shielding mixed cable, comprise shielding six classes or seven class copper cables, this shields and comprises four pairs of pair twist electric wires in six classes or the seven class copper cables, separates the crossing skeleton of four pairs of pair twist electric wires and from inside to outside be wrapped in its outside screen and oversheath successively; Every pair twist electric wire is made of the core outsourcing insulation again; 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 " shielding six classes or seven class copper cables " promptly is meant existing standard on the market and shielding six class cables (STP Cat.6) and shields seven class cables (STP Cat.7).

The utility model design principle is: the utility model is at the center drilling of the crossing skeleton of existing shielding six classes or seven class copper cables, in the hole, place optical fiber, be about to shield six classes or seven class copper cables have been transformed into photoelectricity mixing 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 utility model compared with prior art has following advantage:

1, because the utility model adopts the crossing skeleton center of 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, same crossing skeleton center owing to the utility model employing shielding six classes or seven class copper cables adds the structure of optical fiber, and is simple on the structure, saved the sheath and the reinforcement material of optical fiber, and consumptive material is few, and cost is low.

3, same because the utility model adopts the crossing skeleton center of shielding six classes or seven class copper cables to add the structure of optical fiber, and overall volume is equal to general 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 in the utility model all adopt fluoroplastics, the utility model integral body is not combustion-supporting, do not burn yet, and oxygen index 〉=95 can continuous operation under 200 ℃～250 ℃ high temperature.
