Embodiment
Present embodiment is the preferred embodiment for the present invention, and other all its principles are identical with present embodiment or approximate with basic structure, all within protection range of the present invention.
Please referring to accompanying drawing 1, the utility model is a kind of data isolation multichannel transparent transmission OLT of novel integrated concentrator function, comprises in the utility model that (also can be described as is the data network interfaces for more than one light mouth and more than one network interface; Be mainly used in transmitting data stream), wherein, the light mouth can be connected with optical fiber; Realize transfer of data, network interface can be connected with the netting twine of RJ-45 interface, realizes transfer of data; Also be provided with a main control chip in the utility model, light mouth and network interface are connected on the main control chip, in the utility model; Also be provided with a management network port, be used to realize the transmission of management data, management network port also can be connected with the netting twine of RJ-45 interface; In the present embodiment, management network port also is connected on the main control chip.Can realize data penetration transmission between light mouth and the network interface through main control chip, data penetration transmission between management network port and the light mouth.In the present embodiment, data penetration transmission is via the inner data physical isolation that realizes of main control chip, wherein; The light mouth can be connected to the ONU unit; Network interface is connected to ethernet terminal, and the management mouth is connected on the descending network interface of core board, during practical implementation; Network interface can provide the user side access internet, and the light mouth can be connected to the various terminal equipments through ONU of Optical Fiber Transmission.In the present embodiment, light mouth and network interface can be realized transparent transmission, management network port and light effected transparent transmission, and two kinds of filtering rules that interchannel transfer of data then is provided with by main control chip are realized the data isolation between the intranet and extranet.
Please referring to accompanying drawing 2, in the present embodiment, the external core board system of OLT comprises a core board and the uplink network port that is connected with core board, descending network interface.Realize transfer of data through uplink network port, be linked into the management network port of OLT, both can be configured management, also can realize that core board transmission data are via the transfer of data of management network port to the light mouth simultaneously OLT through descending network interface to main website.In the present embodiment, the data transaction of agreements such as T645 agreement and T376.1 agreement is realized in core board inside, has realized the management function of concentrator.
Through contrasting traditional OLT and the difference of the OLT in the utility model in networking, more can highlight the advantage of the utility model.
Please referring to two sketch map networking modes in accompanying drawing 3 and the accompanying drawing 4:
Please referring to accompanying drawing 3; In typical OLT ammeter networking application network; Mainly comprise main website amr server, traditional OLT, ONU optical module, concentrator, collector and ammeter, ammeter output signal inputs to collector respectively, and collector is again with sending to concentrator in the set of signals; Concentrator sends to traditional OLT through the ONU optical module, gives the main website amr server by OLT through Optical Fiber Transmission again.
Please referring to accompanying drawing 4; During the networking of the data isolation multichannel transparent transmission OLT of the integrated concentrator function of employing the utility model is used; Mainly comprise main website amr server, the utility model OLT, optical splitter, ONU and ammeter; Ammeter is transferred to optical splitter through ONU with signal, after optical splitter is integrated, exports to the utility model OLT, and then gives the main website amr server through Optical Fiber Transmission.
Contrast by above-mentioned two kinds of networking plans can find out that when adopting the utility model OLT networking to use, the networking link of having saved collector, concentrator etc. has reduced networking cost, realizes the whole network Optical Fiber Transmission, has greatly improved the efficient of transfer of data.Particularly in traditional OLT technology, can't realize that OLT transmits in the direct net of main website, need like wireless access technologys such as practical GPRS, WIFI, WiMAX, user's networking cost strengthened by extra transmission channel, laser propagation effect be also undesirable.In traditional OLT networking mode, intelligent electric energy meter normally communicates through RS-485 bus, PLC power line carrier etc., adopts the electric energy meter of RS-485 bus communication, and its communication distance is shorter, and generally in hundreds of rice scope, the scope of application is limited; And the electric energy meter that adopts power line carrier or wireless mode to communicate by letter; Than last type of electric energy meter; Though communication range has increased; But since power line signal disturbs big or wireless signal a little less than, the image data process is disturbed easily, and the reliability and the transfer of data real-time of the data acquisition of electric energy meter are had a greatly reduced quality.The newly-increased management of the utility model OLT mouthful pass-through channel to the light mouth directly solves transmission problem in the net, and has realized the physical isolation of data in OLT inside, and the safe transmission of data is guaranteed.The particularly networking of the utility model OLT directly provides OLT through the transmission mode of optical splitter to ONU, has evaded the drawback of traditional networking model.Along with the construction of Chinese intelligent grid, intelligent optical fiber electric energy meter has been promoted and has been born, and cooperates the utility model OLT, more perfectly cooperates networking to use, and has objectively promoted the development of industry.Optical fiber communication is the novel communication mode of present high speed, high bandwidth, and the utility model OLT by this in the high speed development of fiber optic applications, provides the Multiservice capability that takes on an entirely new look OLT just.
The above only is the application's a embodiment, should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the application's principle, can also make some improvement, and these improve the protection range that also should be regarded as the application.
