Description

Technical Field

[0002] The daily operation and maintenance of optical fiber networks is the after-sales management of optical fiber networks. Its main purpose is to ensure the long-term operation of optical fiber networks and to ensure that users can find the fault point as soon as possible when there is a problem with the network. With the development of information technology, the number of IoT devices has gradually increased, and the number of optical fiber equipment lines has reached an unprecedented level. In order to ensure the normal operation of the home IoT, some families have more than one optical fiber channel. As a result, the increase in optical fiber lines has greatly increased the cost of optical fiber operation and maintenance.

[0003] When searching for resources at the household end-splitter, the address of the optical port of the fiber splitter box cannot be clearly named, and only the business name is printed on the paper label. In addition, the fiber splitter box is outdoors, and the paper label is easily exposed to the sun, wind and rain. The paper label ages quickly and the handwriting is blurred. When users perform maintenance, they have to turn on the red light at the household entrance, unplug the connector in each fiber splitter box and look at the red light to find resources. This is inefficient and affects the network experience of other users. Since there are many lines, if there is a problem with the optical fiber line, the operation and maintenance personnel need to use optical path testing equipment to check the damaged lines one by one during the inspection, which makes the later management and troubleshooting difficult and the operation and maintenance pressure high.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0029] Reference Figure 1-3The utility model provides an embodiment: an optical network operation and maintenance management system, including a splitter 1, the splitter 1 is connected to a loss monitor 2, an optical modem 3 and a wavelength division multiplexer 6 through an optical fiber, and the wavelength division multiplexer 6 WDM is a communication technology that combines a series of optical signals carrying information but with different wavelengths into a beam and transmits them along a single optical fiber; at the receiving end, a certain method is used to separate the optical signals of different wavelengths. The wavelength division multiplexer adopts this technology. When a broadband light is input to an optical fiber port of a central office device, if the branch network below the port is broken, when its cross section is reflected, part of the light will be reflected back to the central office. The spectrum of the reflected light can be compared with the wavelength of the absorption peak of the reflection spectrum to know which optical branch has a problem at which level. In the same principle, if a broadband light is input to a user terminal, the central office will also receive a similar spectrum. By comparing different spectrum absorption peaks, it can be known from which branch the light of this terminal is transmitted, and thus the network topology of this terminal can be marked to detect the damage of the optical fiber and realize the positioning of the optical fiber. The wavelength division multiplexer 6 and the loss monitor 2 are both connected to the spectrum analysis and identification device 7 through optical fiber. When the loss monitor 2 is used, the original optical fiber adapter is removed, the connector end face in the tray is cleaned, the routing loss monitor 2 is replaced, and the standard jumper is inserted. Red light is injected into one end of the standard jumper. The intensity of the refracted red light is observed through the optical loss monitoring window to see whether it penetrates the refracted light indicator ruler, and whether the quality of the coupling end face of the cable end meets the requirements, thereby reducing the waste of jumpers and the sinking of cable resources. As the business volume increases year by year, pipeline congestion becomes increasingly serious, and cable resources become increasingly scarce, providing a basis for subsequent optical port repair. According to the data, the efficiency and intactness of jumpers and cables are improved. The optical modem 3 is connected to the router 4 through a signal line. The router 4 is connected to the client 5 through the WLAN protocol. The loss monitor 2 includes a red light port 13, a jumper 14, an optical loss monitoring window 15, an intelligent optical port coupler 16, and a jumper end 17. The normal operation between the optical modem 3 and the router 4 is directly determined by the superior optical fiber, so the maintenance of the optical fiber operation in the later stage is particularly important. The management of optical network operation and maintenance is the stability management of optical fiber optical signal transmission, so the detection of optical fiber optical signals by the loss monitor 2 is very important.

[0030] The spectrum analysis and identification device 7 is a fiber optic spectrometer, which can accurately detect whether the optical signal is normal or not. Combined with the loss monitor 2 and the wavelength division multiplexer 6, it can quickly locate the optical fiber problem point, which is convenient for later maintenance. The client 5 includes a laptop computer 8, a desktop computer 9, a set-top box 10, a smart home module 11 and a TV 12. The strength of the indoor signal is directly determined by the optical modem 3. The set-top box 10 and the TV 12 are connected through the CEC protocol communication. The communication protocol can ensure that the client 5 can be normally operated and used. Combined with the stability of the optical signal, the use effect of the client 5 is improved. The smart home module 11 includes an indoor lighting system, curtain control, air conditioning control, a security system and network home appliance control. The jumper 14 is respectively connected to the red light port 13 and the light loss monitoring window 15, and the intelligent optical port coupler 16 is respectively connected to the jumper end 17 and the light loss monitoring window 15. The jumper end 17 is connected to the splitter 1, and the red light port 13 is connected to the output end of the spectrum analysis and identification device 7. When actually used, the jumper end 17 is connected to the splitter 1, and the red light port 13 is connected to the external red light emission source to ensure that the damage point of the red light test optical fiber is detected, and the damage point of the optical path is determined in time to facilitate later operation and maintenance repair.

[0031] Working principle: When the optical network operation and maintenance management system is running, if there is a problem with the optical path, the later operation and maintenance personnel will use the wavelength division multiplexer 6 to identify the optical signal spectrum status at the front end or back end of the splitter 1, and then use the spectrum analysis and identification equipment 7 to check whether the optical signal is normal. At the same time, the loss monitor 2 will pass red light to give the optical fiber a specific optical signal to check the problem point of the optical signal. This two-pronged approach can be used to locate the damaged point of the optical signal at the same time. This setting can ensure that the optical fiber can be quickly located when it is running, with high operation and maintenance efficiency and low pressure in the later stage.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
