Abstract
The utility model discloses a kind of EOC jumper, comprise two CATV signal input ports, an extraneous power interface of eoc signal input port, a mixed signal output port and multiple AC, wherein, described two CATV signal input ports are connected to mixed signal output port respectively through multistage high pass filter, described eoc signal input port is connected to mixed signal output port through multiple-order low-pass filter, and the extraneous power interface of described AC connects with corresponding multistage high pass filter or multiple-order low-pass filter respectively.The utility model adopts multistage filter to carry out filtering, make separation signal thus consider thorough, and the utility model structure is simple, and the life-span of use is long.Meanwhile, both ensure that the amplification in a network of CATV signal, do not affected again the signal of EOC.
Description
Technical field
The utility model relates to the auxiliary equipment of communication equipment, particularly a kind of EOC jumper.
Background technology
Jumper is used for Unidirectional magnifier place provides the equipment of up-downgoing passage for several signal, when not changing original Unidirectional magnifier, increasing CableBlaze data jumper, making original unidirectional TV network become two-way data network.
At present, existing jumper thorough not to the filtering of separation signal, thus causes two signals also to there is interactional problem.
Utility model content
Utility model object: for above-mentioned prior art Problems existing and deficiency, the purpose of this utility model be to provide a kind of can the EOC jumper of more thorough filtering.
Technical scheme: for realizing above-mentioned utility model object, the technical solution adopted in the utility model is a kind of EOC jumper, comprise two CATV signal input ports, an eoc signal input port, a mixed signal output port and the extraneous power interface of multiple AC, wherein, described two CATV signal input ports are connected to mixed signal output port respectively through multistage high pass filter, described eoc signal input port is connected to mixed signal output port through multiple-order low-pass filter, the extraneous power interface of described AC connects with corresponding multistage high pass filter or multiple-order low-pass filter respectively.
Further, equipotential lightning protection circuit is equipped with at described each CATV signal input port, eoc signal input port and mixed signal output port.Adopt equipotential lightning protection circuit effectively can increase the useful life of device in circuit, meanwhile, when waiting the device in circuit lightning protection circuit to go wrong, wait circuit lightning protection circuit not output current, thus serve the effect of warning.
Further, the inductance in described high pass filter and low pass filter adopts high permeability manganese bar magnet wire-wound inductance.Make the better effects if of filtering like this.
Beneficial effect: compared with prior art, the utility model adopts multistage filter to carry out filtering, make separation signal thus consider thorough, and the utility model structure is simple, and the life-span of use is long.Meanwhile, both ensure that the amplification in a network of CATV signal, do not affected again the signal of EOC.
Accompanying drawing explanation
Fig. 1 is electrical block diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
As shown in Figure 1, a kind of EOC jumper, comprise two CATV signal input port 1a and 1b, an eoc signal input port 2, mixed signal output port 3 and the extraneous power interface 4 of multiple AC, wherein, one CATV signal input port 1a is connected with one end of an AC power interface 4a one end, the external world and electric capacity C19 respectively through the first equipotential lightning protection circuit 5a, and the other end of electric capacity C19 is connected with the first multistage high pass filter 6a; The one AC extraneous power interface 4a other end is connected with the extraneous power interface 4b of the 2nd AC by plug K switch 1; 2nd CATV signal input port 1b is connected in one end of power interface 4c extraneous with the 3rd AC and one end of electric capacity C32 respectively through the second equipotential lightning protection circuit 5b, and the other end of electric capacity C32 is connected with the second multistage high pass filter 6b; The other end of the extraneous power interface 4c of the 3rd AC is connected with the extraneous power interface 4d of the 4th AC by plug K switch 2; Eoc signal input port 2 is connected with one end of electric capacity C1 respectively at the 3rd equipotential lightning protection circuit 5c, the other end of electric capacity C1 is connected with multiple-order low-pass filter 7, the output of multistage high pass filter and multiple-order low-pass filter through electric capacity C7 and the 4th equipotential lightning protection circuit 5d to mixed signal output port 3.
Utilize CATV signal in 111 ~ 860MHz frequency transmission; Eoc signal passes through impedance transformation, after balance/non-equilibrium conversion, in the characteristic of 1 ~ 20MHz frequency transmission, by installing wave multiplexer before coaxial cable centralized distribution device, the ethernet signal export ONU and CATV signal syntheses deliver to user at Coaxial Cables.
In the present embodiment, the inductance in low pass filter and high pass filter all adopts high permeability manganese bar magnet wire-wound inductance, the maximum 60V/10A of electric current.Adopt multiple-order low-pass filter, make filtered frequency range be 5-30MHz; Adopt multistage high pass filter, make filtered frequency range be 47-1000MHz; Make separation signal like this thus filter thorough, be not respectively affected.Also adopt multi-step temperature compensating circuit in the present embodiment, make the utility model at catv network, unaffected under weather temperature height low environment, product skewer enters that loss is little, the high performance processed of reflection is good, and isolation is high.Stable work in work, there is good waterproof, anticorrosion, function of seismic resistance.
