Abstract
The utility model discloses a coaxial feedback power supply used for FTTH (Fiber To The Home). The coaxial feedback power supply comprises a power adapter, a first capacitor and a firs inductor. The first capacitor is connected in series with a coaxial cable, one end of the first capacitor is connected with a user terminal, and the other end of the first capacitor is connected with an information processing platform. One end of the first inductor is connected with the power adapter, and the other end of the first capacitor is connected with the other end of the first capacitor. The coaxial feedback power supply is simple in structure and fully utilizes coaxial resources in homes of users while additional power lines are not required and layout and beautiful appearance of a user's home cannot be affected.
Description
Technical field
The utility model relates to a kind of power supply, particularly a kind of for the fiber-to-the-home coaxial feedback power supply of FTTH.
Background technology
Fiber to the home, and (FTTH) is a kind of transmission method of optical-fibre communications, be directly optical fiber receive user family in (place that user is required).Particularly, FTTH refers to optical network unit (ONU) is arranged on to household user or enterprise customer place, be in light access series except FTTD (fiber to the desk) the most close user's optical access network application type.The remarkable technical characterstic of FTTH is the bandwidth that not only provides larger, and has strengthened the transparency of network to data format, speed, wavelength and agreement, has relaxed the requirement such as environmental condition and power supply, has simplified and has safeguarded and install.But optical fiber main line has arrived given place in user family, can not arrive each room of user family, if other rooms need the Two-way of wiring logging-on function and cable TV, need extra bracing wire, this seriously damages layout of houses.Nowadays, the wiring in most houses is all interior lines, and a kind of equipment can connect coaxial line transmission Ethernet and cable TV signal, and realizing each room can wiring logging-on function and cable TV Two-way.
What the FTTH of telecommunications adopted is data platform, adopts multicast mode, and a PON mouth is 1.25Gbps, and generally Fiber to the home is a PON Kou Dai 64 road ONU, almost can not transmit a set of high-definition television program; Be that two platforms are RF broadcast platform and data platform and the FTTH of CATVA adopts, the bandwidth of 1.3GHz, and the actual 6Gbps code stream that can transmit, can transmit hundreds of cover high-definition television program.
No matter be the equipment of telecommunications or the equipment of CATVA, in indoor layout, always put near the position of optical fiber port, this make equipment may from power supply away from, be difficult for power taking.Meanwhile, the electric wire that elongation degree is grown also can affect the attractive in appearance of user family, reduces user's satisfaction.
Utility model content
It is a kind of for the fiber-to-the-home coaxial feedback power supply of FTTH, not only simple in structure that the purpose of this utility model is to provide, and make full use of the coaxial resource in user family, avoids drawing in addition power line, do not affect layout and attractive in appearance in user family.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of for the fiber-to-the-home coaxial feedback power supply of FTTH, comprise power supply adaptor, the first electric capacity and the first inductance, described the first capacitance series is in coaxial cable, one end is for being connected with user terminal, the other end is for being connected with the information processing platform, described first inductance one end is connected with described power supply adaptor, and the other end is connected with the described first electric capacity other end.
Aforementioned the first electric capacity plays buffer action to low frequency signal, and the first inductance plays Intercepting effects to high-frequency signal, and they ensure that uplink returns the signal of returning and only has data-signal, and can be smoothly through coaxial line and send in user's equipment.
Further, described power supply adaptor adopts 12V power supply adaptor, for 220V alternating current being converted to the direct current of 12V.
Operation principle of the present utility model is as follows:
Up direction: data-signal by user terminal through the first electric capacity, then the first inductance to the Intercepting effects of high-frequency signal under, data-signal can not enter power supply adaptor, and is admitted in the information processing platform; Meanwhile, after power supply adaptor is processed, transfer the direct current of 12V by the 220V alternating current of inputting to, through the first inductance, the first electric capacity to the buffer action of direct current signal under, the direct current of 12V is sent into the equipment of the information processing platform, make equipment carry out work.
Down direction: in the time that data-signal is returned by the information processing platform, under the effect of the first inductance, data-signal only can, through the first electric capacity, then enter user terminal; Under the effect of the first electric capacity, direct current is blocked, and can not enter user terminal.
Compared with prior art, the beneficial effects of the utility model are: simple in structure, the coaxial cable resource that can make full use of in user family is information processing platform power supply, solve the problem of information processing platform power taking difficulty, avoided, because drawing in addition power line to affect wiring and overall appearance in user family, having ensured user's user satisfaction simultaneously.
Brief description of the drawings
Fig. 1 is for the fiber-to-the-home coaxial feedback power supply of FTTH circuit diagram in actual applications in the utility model one preferred embodiment.
Embodiment
Consult Fig. 1, this is used for the fiber-to-the-home coaxial feedback power supply of FTTH and comprises 12V power supply adaptor P, the first capacitor C 1 and the first inductance L 1; First capacitor C 1 one end is connected with user terminal U1 through coaxial cable, and the other end is connected with information processing platform U2 through coaxial cable, and first inductance L 1 one end is connected with 12V power supply adaptor P, and the other end is connected with first capacitor C 1 other end.
The first capacitor C 1 plays buffer action to low frequency signal, the first inductance L 1 plays Intercepting effects to high-frequency signal, they ensure that uplink returns the signal of returning and only has data-signal, and can be smoothly through coaxial line and send in user terminal U1, and data-signal is by the direct current transmission of 12V.
Below be only concrete exemplary applications of the present utility model, protection range of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
