Abstract
The utility model relates to an optic fiber coaxial composite cable which is provided with a coaxial cable with optic fibre. An optic fiber ferrule and an optic fiber are arranged between the core wire of the coaxial cable and a shielding layer. The utility model has the advantages that the optic fiber is combined with the coaxial cable into a whole. The coaxial cable is the carrier and also the transmission conductor of the optic fiber, which can realize the bidirectional transmission through only one cable. The optic fiber transmits signals downward, and the coaxial cable transmits signals backward. The frequency is reused, and the back transmission frequency band is improved. The utility model realize the last kilometer network optic fibre transmission system to home. The utility model is constructed only one time and needs no reconstruction. The construction of the network is simple, and the back transmission problem can be efficiently eliminated.
Description
The utility model relates to a kind of telecommunication cable, especially a kind of fiber-coaxial composite cable.
Existing optical cable and coaxial cable all are single functions, and the construction of cable TV integrated information net all is that main line is made up of optical cable, the opto-electronic conversion by optical node with coaxial cable to user terminal.Narrow for transmitted in both directions, back transmission band, bottleneck, funnel, noise, distortion, shortwave, impulse disturbances arranged, a difficult problem such as the crowded and transmission equipment of frequency band is many.
In order to overcome the deficiency of existing optical cable and coaxial cable, the utility model provides a kind of fiber-coaxial composite cable, and this cable can not only transmitting optical signal, can also provide great convenience to construction by transmission of electric signals, once construction is no longer transformed, and Fiber to the home to realize " last kilometer ".
The technical scheme that its technical problem that solves the utility model adopts is: be provided with ferrule and optical fiber between the heart yearn of coaxial cable and screen, the optical fiber radical can be established as required, and its advantage is that optical fiber and coaxial cable are one.Coaxial cable is that the carrier of optical fiber is again a transmission conductor, and coaxial cable core wire available copper Baogang strengthens the pulling force protection optical fiber of optical fiber, and optical fiber and ferrule are minimum to be one.Fiber to the home can do down and pass to improve transmission frequency and and do not disturb, and coaxial doing passes back to optical node and returned by optical fiber, improves the passback frequency, accomplishes channeling, realizes a cable transmitted in both directions, and existing equipment just can be finished transmission, and networking is simple, has eliminated the difficult problem of simultaneous interpretation.
The beneficial effects of the utility model are, can the transmitting optical signal and the signals of telecommunication, improve the passback frequency, and realize that photosignal transmits simultaneously, eliminated the difficult problem of passback, simple in structure, save other material of optical cable, once construction is no longer transformed.
Below in conjunction with drawings and Examples the utility model is further specified.
Figure is a fiber-coaxial composite cable combination assumption diagram.
Shown in the figure, the fiber-coaxial composite cable is made up of heart yearn 1, ferrule 2, optical fiber 3, insulating barrier 4, screen 5 and external protection 6, in the insulating barrier 4 of ferrule 2 between heart yearn 1 and screen 5.
Claims (3)
1, a kind of fiber-coaxial composite cable, it is characterized in that: it is made up of heart yearn, ferrule, optical fiber, insulating barrier, screen and external protection, in ferrule and the optical fiber insulating barrier between heart yearn and screen.
