Abstract
The utility model relates to a novel cable bridge device power supplied by coaxial cable, which comprises a Cable Bridge Modem, a power passing tap, a power passing distributor, a power passing mixer and a Cable Bridge Switch; the Cable Bridge Modem, the power passing tap, the power passing distributor, the power passing mixer and the Cable Bridge Switch are connected with each other in sequence through a Coax (coaxial cable), a lower voltage DC power and a network data signal produced from the Cable Bridge Modem is transferred to the power passing distributor after mixed by the power passing tap, the power passing distributor can mix the multi-path transferred signal, the mixed signal is transferred to the power passing mixer later, the power passing mixer can separate the low voltage DC power out from the mixed signal, and transfers the low voltage DC power to the Cable Bridge Switch for power supplying. Compared with the prior art, the utility model has the advantages of that the cable bridge switch device, which needs to connect with power supplying unit from the outside of a corridor, does not need the additional power supplying unit anymore, so that the construction project becomes easier.
Description
Technical field
The utility model relates to a kind of electric supply installation of broadband device, particularly relates to the device of a kind of novel cable bridge device by coaxial cable power supply.
Background technology
Its networking of existing cable TV network is adopted passive device mostly at the finger assignments net near user side, having only the amplifier of prolongation is active equipment, adopt the method for powering on the coaxial wire, from the image intensifer of local side is its power supply, like this cable TV network of whole community corridor does not need external power supply, and its structure as shown in Figure 1.
Cable Bridge (cable bridge) provides the new network equipment of home network interconnect function.It uses the above frequency of 860M, allows the user to set up the home network of bandwidth up to 270M on family's existing wired camera cable.Simultaneously, the user needn't worry to destroy or disturb original cable TV signal again.
Cable Bridge can provide high speed broadband service as a kind of novel coaxial cable high speed transmission technology on coaxial cable.But the equipment of Cable Bridge all is active equipment, will produce a powerup issue, and especially Cable Switch equipment is its power supply because physical location in corridor, need draw a power line in addition.If adopt the mode of the line powering of original cable TV, various active equipments to CATV are powered, after TV signal and low-voltage DC (being generally 60V) passed through electric splitter, send into Cable and be sent to the electric splitter of mistake of user side, crossing electric splitter separates CATV signal wherein with low-voltage DC, wherein the CATV signal continues transmission, and low-voltage DC powers then for Cable Bridge Switch, as shown in Figure 2.
But adopt the mode of this line powering, need to change original inactive component of existing finger assignments net, cost is very high.And Cable Bridge equipment is mainly used in the high speed data transfer in the home network, if adopt the mode of external power supply, just need carry out the external power supply of 220V, and this will increase the cost and the difficulty of construction.
Summary of the invention
The purpose of this utility model is exactly to provide the device of a kind of novel cable bridge device by coaxial cable power supply for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions: a kind of novel cable bridge device is by the device of coaxial cable power supply, it is characterized in that, comprise Cable Bridge (cable bridge) Modem, cross electric splitter, cross electrical distributor, cross electric mixer, Cable Bridge Switch, described Cable BridgeModem, cross electric splitter, cross electrical distributor, cross electric mixer, Cable Bridge Switch connects by Coax (coaxial cable) successively, low-voltage DC that described Cable Bridge Modem produces and network data signals were transferred to electrical distributor by crossing after electric splitter mixes, cross electrical distributor multichannel is uploaded the signal mixing, mixed signal was transferred to electric mixer, by crossing electric mixer low-voltage DC is separated from above-mentioned mixed signal, and low-voltage DC is transferred to Cable Bridge Switch is its power supply.
Be about to the CATV signal of network data signals, low frequency of high frequency under the electric mixer of described mistake and mix, on be about to network signal and separate with direct current.
Described Cable Bridge Modem converts outside 220V high-tension electricity to low-voltage DC by the AC/DC adapter of inside.
Described low-voltage DC can be according to the equipment requirements adjustment, as 36V.
Described 36V direct current is converted to little low-voltage DC by the DC/DC transducer, as 3.3V.
Compared with prior art, a kind of novel cable bridge device that adopts above technical scheme has characteristics such as cost is low, resource utilization is high, power saving by the device of coaxial cable power supply.

Fig. 2 is another kind of prior art constructions schematic diagram;
Fig. 3 is a structural representation of the present utility model;
Fig. 4 is a Cable Bridge Modem electric supply installation schematic diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 3, a kind of novel cable bridge device is by the device of coaxial cable power supply, the Cable Bridge Modem of user inside produces low pressure 36V direct current, sends on the Cable after passing through electric splitter acting in opposition, oppositely is sent to outdoor Cable Bridge Switch again and is its power supply.
Wherein, cross the 36V low-voltage DC that electric splitter produces Cable Bridge Modem and upload signal and mix upwards transmission of back.After crossing electrical distributor multichannel being uploaded signal (comprising the CATV signal) and mixed, continue upwards transmission.Cross electric mixer with the 36V low-voltage DC, from separating by crossing the electrical distributor signal that upwards transmission comes, and it is passed to Cable Bridge Switch is its power supply.
As shown in Figure 4, the electric supply installation of Cable Bridge Modem, Cable Bridge Modem converts outside 220V high-tension electricity to low pressure 36V direct current by its AC/DC adapter.Wherein the 3.3V direct current is powered as himself, and 36V is sent on the Cable, realizes the function of POC (POWER OVER CABLE).
