The invention discloses an FTTx centralized type optical measuring system, which comprises an optical fiber coupler module, a monitoring instrument, a client computer, an interchanger, a server and a warning lamp, wherein the client computer, the interchanger, the server and the warning lamp are in remote control, the optical fiber coupler module and the monitoring instrument are installed and connected, the monitoring instrument comprises an OTDR (optical time domain reflectometer) and an optical switch which are respectively connected with the interchanger and are connected with the client computer, the server and the warning lamp through the interchanger, and the optical fiber coupler module is arranged on an optical fiber distributing frame and is communicated with local optical cables. The FTTx centralized type optical measuring system has the advantages that the process is simple, the use is convenient, the regular or continuous detection on an external optical fiber network can be realized in a central machine room, in addition, when the failure occurrence is detected, the failure kind can be analyzed, and the warning is given out.
Description
Technical field
The present invention relates to communication technical field, be specially the centralized light measurement system of a kind of FTTx.
Background technology
FTTH (Fiber To The Home, fiber-to-the-home front yard) is the direction that optical fiber communication further develops, and it is acknowledged as desirable broadband access network.At present, so-called broadband services, is the movie and video programs of 500kbps mostly.Operator, in order to make full use of copper cash resource, adopts ADSL (Asymmetric Digital Subscriber Line, ADSL (Asymmetric Digital Subscriber Line)) technology just can provide, and this time that makes FTTH become Access Network main flow postpones to some extent.In the near future, in the universal situation of HDTV (High Definition Television, HDTV (High-Definition Television)), ADSL can not meet the demands, and advanced ADSL2+ also permits and meets 1chHDTV/ family, if 4chHDTV/ family adopts FTTH more reasonable.The in the situation that of two-way services extensive use, the asymmetric ADSL of up-downgoing is difficult to correspondence.At present, the FTTH of developed country builds and generally carries out, and Japan, Korea S and the U.S. are more flourishing, adopt various passive optical network PON (Passive Optical Network) and and network technology.Operator and the real estate developer of China have carried out pilot to FTTH.Yet, at present to the construction of light network and maintenance, all need professional and technical personnel to be with the various instruments such as OTDR (Optical Time Domain Reflectometer, optical time domain reflectometer) to set out scene and go to detect, investigation failure mode and reason.The maintenance of this mode, both time-consuming, take again manpower and materials.
Summary of the invention
The object of this invention is to provide the centralized light measurement system of a kind of FTTx (RFTS, Remote Fiber Testing System), to solve the shortcoming in above-mentioned background technology.
The present invention is achieved in that the centralized light measurement system of a kind of FTTx, comprise fiber coupler module (Test Access Module-TAM), monitoring instrument, and the client computer of Long-distance Control, switch, server and warning light, described fiber coupler module and monitoring instrument are installed and link together, wherein, monitoring instrument comprises OTDR and optical switch (Optical Switch), be connected with switch respectively, and by switch contact customer end computer, server and warning light, described fiber coupler module is arranged on fibre distribution frame (ODF, Optical Distribution Frame) on, and be communicated with optical cable not in the know.
In the present invention, the monitoring instrument of RFTS system, server, warning light, client computer are realized and being interconnected by netting twine, thereby can realize Long-distance Control, at a central machine room, by the connection of general networking, can control the monitoring instrument in the local side of distant place, carry out the test of fiber optic network.
Technique of the present invention is simple, easy to use, so can regularly or continuously detect outside fiber optic network row at central machine room, and can be when discovering fault generation, the kind of fault is analyzed and given the alarm, by fault message, by the relevant director of form notice or maintenance personals such as Email or news in brief, this will significantly reduce fibre circuit and keep in repair the needed time, improve resume speed.
Accompanying drawing explanation
The connection diagram that figure l is preferred embodiment of the present invention
Embodiment
Below in conjunction with drawings and Examples, the present invention is further elaborated.
Referring to Fig. 1, the centralized light measurement system of a kind of FTTx, comprise fiber coupler module, monitoring instrument, and the client computer of Long-distance Control, switch, server and warning light, described fiber coupler module and monitoring instrument are installed and link together, wherein, monitoring instrument comprises OTDR and optical switch, be connected with switch respectively, and by switch contact customer end computer, server and warning light, described fiber coupler module is arranged on fibre distribution frame, and is communicated with optical cable not in the know.
In the present invention, described RFTS system, can realize the monitoring of standby optical fiber, also can realize on-line monitoring, by being configured in the fiber coupler module on fibre distribution frame, can, by closing ripple from signal of communication light (OLT signal, optical line terminal signal) and measuring-signal light, then be input in external cable together.At the ONU of user side (Optical Network Unit, optical node) before, need to add a ultimate filter (termination Filter-TF), filter out test signal light, in order to avoid its impact on ONU.
At fiber optic network, build period, can at central machine room, to the quality of outside fiber optic network, detect at any time, and the scene of needn't setting out is gone, meanwhile, RFTS system can be carried out quality testing to the whole link of fiber optic network, makes final acceptance of construction more simple and convenient.
In fiber optic network O&M period, can the quality of outside fiber optic network be carried out regularly or continuously be detected, and can be when discovering fault generation, the kind of fault is analyzed and given the alarm, by fault message, by forms such as Email or news in brief, notify relevant director or maintenance personal, when fiber cable run line failure, if there is associated electrical map to match, RFTS can also indicate the place that fault occurs on map.
