Abstract
The utility model discloses an optical fiber for transmitting data and supplying electricity to networks. The optical fiber is in a three-layered structure, wherein the first layer is an optical fiber core, the second layer is a coat, and the third layer is an outer protective casing; the coat is covered on the optical fiber core, and the outer protective casing is covered on the coat. The optical fiber also comprises a transmission line for a direct-current power supply, and the transmission line for a direct-current power supply is positioned between the coat and the outer protective casing. When the optical fiber of the utility model is used for transmitting media for the networks, an inner core of an original optical fiber structure is still used for transmitting data, and the transmission line for a direct-current power supply is used for transmitting direct current. Therefore, the utility model can solve the problems of data transmission and electricity supply transmission in the electricity supply of the networks by utilizing a simple technical scheme.
Description
Technical field
The utility model relates to the far-end electric supply installation of network power supply equipment, more specifically refers to a kind of optical fiber that transmits data and network power supply.
Background technology
Along with the develop rapidly of adopting the Power-over-Ethernet technology, and adopt the superiority of Power-over-Ethernet little by little to embody.In the development of network technology, household electrical appliances, communication and the Bluetooth technology in suitable one period future from now on, Power-over-Ethernet certainly will permeate in its every field.From always with the IEEE 802.3af standard of the serious international Electronic Engineering Association approval that is celebrated also as can be seen this technology will bring advantage at aspects such as energy conservation, security of operation, the realization of Power-over-Ethernet also can make your notebook no longer need the battery of any heaviness and loaded down with trivial details plug in the future, as long as you can connect to network, netting twine will be powered for your networked devices automatically.Please consult shown in Figure 1ly earlier, as the terminal user, it is by network interconnection device (as switch, router) login internet, perhaps a certain Metropolitan Area Network (MAN) or LAN (Local Area Network).According to the thought of Power-over-Ethernet, network interconnection device is supplied by UPS and is used direct supply, and terminal user's power supply comes from network interconnection device.In present technology, the terminal user is connected with the employing Category-5 twisted pair that is connected with between the network interconnection device, and the employing optical fiber that has connects, to carry out data transmission.When adopting Category-5 twisted pair to connect, as long as supply lines is then selected idle electric wire in the twisted-pair feeder for use; When adopting optical fiber to connect, optical fiber can only carry out data transmission, and can not carry out the power supply transmission.So how utilizing optical fiber to carry out data transmission and power supply transmission, is in face of the pendulum personage in the field of business and a practical problems must solving.
Summary of the invention
The purpose of this utility model provides a kind of optical fiber that transmits data and network power supply, utilizes this optical fiber to solve the data transmission in the Power-over-Ethernet and the problem of Power-over-Ethernet.
To achieve these goals, the utility model adopts following technical scheme:
A kind of optical fiber that transmits data and network power supply, this optical fiber are three-decker, and ground floor is a fiber cores, and the second layer is a covering, and the second layer is an outer jointing jacket, and covering is coated on fiber cores, and outer jointing jacket is coated on covering,
Wherein,
This optical fiber also comprises the transmitting DC line, and the transmitting DC line is between covering and outer jointing jacket.
Described transmitting DC line comprises two at least.
Described transmitting DC line is a twisted pair construction.
In technique scheme of the present utility model, in traditional optical fiber structure, added the transmitting DC line, and the transmitting DC line has been embedded between covering and the outer jointing jacket.When optical fiber of the present utility model was used for the transmission medium of network, the inner core in the former optical fiber structure still was used for data transmission, and the transmitting DC line then is used to transmit direct current.Therefore, the utility model has utilized very simple technical solution, has solved data transmission and power supply transmission problem in the network power supply.

Embodiment
For further specifying above-mentioned purpose of the present utility model, technical scheme and effect, in conjunction with above-mentioned each figure the utility model is described in detail by the following examples.
See also shown in Fig. 2,3,
Traditional optical fiber 10 is three-decker, and ground floor is a fiber cores 11, and the second layer is a covering 12, and the second layer is an outer jointing jacket 13, and covering 12 is coated on fiber cores 11, and outer jointing jacket 13 is coated on covering 12.The materials of covering can adopt glass also can adopt plastics, adopt glass usually at the initial stage of optical fiber development, in order to reduce cost, in present and future, adopt plastics.
Ground floor optical fiber 11 cores are called kernel again, and one or more glass or plastic optical fibre are arranged usually, and it is to be used for transmitting data.Every glass or plastic optical fibre comprise two strands usually again, and one is used to send data, and one is used to receive data.
The second layer 12 coverings are one deck glass or the plastics that are coated on fiber cores 11 outsides, and it is as mirror light reflected back center, and reflection way is according to transmission mode and difference.
The 3rd layer of outer jointing jacket 13 is the senior polymer fibers of one deck, and it is covered on the second layer, plays a protective role.
Please again in conjunction with Fig. 4, shown in Figure 5,
Described transmitting DC line 24 comprises two at least.Transmitting DC line 24 can be relatively arranged on the relative both sides of fiber cores 21, also can be arranged at a side of fiber cores 21.
Described transmitting DC line 24 is a twisted pair construction, is promptly twisted together mutually by two lines.Adopting this structure mainly is that the general RJ-45 interface that adopts in consideration and the network is complementary.
When optical fiber 20 of the present utility model was used for the transmission medium of network, the inner core in the former optical fiber structure was used for data transmission, and the transmitting DC line then is used to transmit direct current.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claims variation, the modification of the above embodiment.
