Abstract
The utility model relates to a data mixing and sharing distributor comprising an EOC mixed signal input port, an EOC mixed signal output port and a cable television signal radio frequency output port, wherein the EOC mixed signal input port inputs a mixed signal of data and radio frequency by using an F-type connector, the EOC mixed signal output port outputs a mixed signal of data and cable television by using an F-type connector, and the cable television signal radio frequency output port adopts an F-type connector. The input port is connected to the cable television signal radio frequency output port through a duplexer and a distribution circuit, and the input port is connected to the EOC mixed signal output port through the duplexer, the distribution circuit and a mixing circuit. Data mixing and sharing is realized, and the data mixing and sharing distributor has the advantages of being low in loss, high in isolation degree, small in size and flexible.
Description
Technical field
The utility model relates to a kind of data mixing and shares distributor, and particularly a kind of exclusive data is mixed two distributors with wire signal.
Background technology
Along with growth in the living standard, people are for the increase in demand of amusement, much the phenomenon of many TVs in a family appears in families, and much the people also has the needs of online when seeing TV, so requires home network to have the function of while transmitting network data and cable TV signal; Existing distributor, splitter etc. exist that decay is big, loss big, isolation causes each terminal problems such as rating is fuzzy that interact for a short time.
Summary of the invention
The utility model is the problem that exists at existing distributor, splitter, has proposed a kind of data mixing and has shared distributor, can data mixing share, and loss is little, isolation is high.
The technical solution of the utility model is: a kind of data mixing shares distributor, comprises an EOC mixed signal input port, adopts the mixed signal of F type joint input data and radio frequency; An EOC mixed signal output port adopts F type joint output data and cable TV mixed signal; A cable TV signal radio-frequency (RF) output end mouth adopts F type joint, input port through duplexer, distributor circuit to cable TV signal radio-frequency (RF) output end mouth, input port through duplexer, distributor circuit and hybrid circuit to EOC mixed signal output port.
Described EOC mixed signal input port connects data and cable TV radio frequency mixed signal by coaxial cable, carries out data through duplexer and separates with radiofrequency signal, and duplexer comprises high pass filter and low pass filter.The radiofrequency signal of described high pass filter output is carried out signal through distributor circuit and is distributed, be divided into two, one road signal is through the output of cable TV signal output port, and another road radiofrequency signal is exported from EOC mixed signal output port after blender mixes with the low pass filter outputting data signals.
The beneficial effects of the utility model are: the utility model data mixing shares distributor, when realizing that data mixing shares, has that loss is little, isolation is high, small and exquisite advantage flexibly.
Description of drawings
Fig. 1 shares the distributor schematic diagram for the utility model data mixing.
Embodiment
Data mixing shares the distributor schematic diagram as shown in Figure 1, comprises an EOC mixed signal (RF+DATA) input port RFIN, adopts the mixed signal of F type joint input data and radio frequency; An EOC mixed signal (RF+DATA) output port RFOUT adopts F type joint output data and cable TV mixed signal; A cable TV signal (RF) output port adopts F type joint.
Data and cable TV radio frequency mixed signal are imported through EOC mixed signal input port by coaxial cable, carrying out data through duplexer separates with radiofrequency signal, the radiofrequency signal that high-pass filtering obtains is carried out signal through distributor circuit and is distributed, be divided into two, one road signal is exported through cable TV signal output port TVOUT, can directly connect television terminal, another road TV signal is exported from EOC mixed signal output port after hybrid circuit mixes with the data-signal that low-pass filtering obtains, and can connect the next stage device.
The bandwidth of operation of described data and cable TV mixed signal is: IP data 0.5～30MHz/65MHz; TV radio frequency 47/87MHz～862MHz.Described distribution loss is less than 4dB, and main output loss is less than 0.5dB.
