The invention adopts the principle of backward Rayleigh scattering, and realizes the location of tap points according to the difference of round-trip time and time difference of signals in optical cables at different positions; Regarding vibration sensing, when we knock on the optical cable or the ground, the vibration signal will affect the phase of the light transmitted in the optical fiber. We demodulate the phase information of light by background software and display it in the form of waveform diagram.

Current situation of optical cable resource inventory demand;
With the rapid development of application scenarios and blockchain fields such as 5G, edge computing, industrial Internet, Internet of Things, and smart city construction, the demand for optical fiber communication has increased geometrically; Operators have invested heavily in laying optical cables to meet the communication needs, and maintenance personnel need to be responsible for the availability of optical cables to improve the efficiency of this huge asset, so the operation and maintenance work is facing great challenges.
Current situation of optical cable routing in China;
The number of optical cables is huge and the management is chaotic.
Low utilization rate and unclear routing direction.
Unable to monitor dumb resources.
Lack of means and low maintenance efficiency
Fault location is difficult and network interruption time is long.
The data of the old and new resources are different, so it is difficult to reuse them.
The data entry of optical cable design and construction depends on manpower, which flows between multiple positions and has a high error rate.
Lack of means to check the same route and locate the fault point of optical cable line, low efficiency of emergency repair, consuming a lot of manpower.
The direction of optical cable routing is unreasonable, and it is difficult to clean and optimize in the later stage.
The network construction is adjusted frequently, the accuracy of asset management data is not high, and the data cannot be updated in time.
The use of resources is interdisciplinary, which makes communication difficult and inefficient.

In this equipment, optical fiber is used as a vibration sensor to collect the vibration at the far end, and at the same time, as a carrier of signal transmission, it transmits the reflected signal generated by vibration to the system host. After the analysis, the equipment host gives the signal analysis results through algorithm operation, and the results are fed back to the far end through the Internet. Remote inspection personnel can see the results synchronously with a click, and immediately judge the optical cable route.
The optical cable routing intelligent locator series products can find and locate buried optical cables and pipeline optical cables, realize the generation of specific location data of optical cable junction box, optical fiber breakpoint and optical attenuation point, and provide pipeline construction protection and support services.

Resource inventory
As a vibration sensor, optical fiber collects the vibration at the far end, and at the same time, as a carrier of signal transmission, it transmits the reflected signal generated by vibration to the system host, and the host analyzes and gives the results, which are fed back to the remote inspector through the Internet, and the results can be viewed immediately with a click.

Accurately locate the optical cable route, make use of the characteristics of high equipment sensitivity, combine with high-precision GPS positioning, accurately draw optical cable information, build optical cable GIS map, ensure the construction and maintenance of optical cable, and find optical cable quickly and accurately.
Accurately record all the information of bundled optical cables in the well, intelligently generate optical cable routing reports, and provide a complete API interface. Digital optical cable information can be seamlessly imported into the asset management system, reducing manual input links, reducing error rates and greatly improving management efficiency.
fault location
Lock the fault point accurately and quickly by approximate method, knock on the ground or manhole cover, and you can see the location from the fault point, and locate it accurately by combining with GIS map.
Single person, single machine, fault location, accuracy 2 meters. No need to go down the well, no dependence on labels, automatic information collection, small workload, greatly shortened investigation time and high efficiency.
Same route decision
The same routing of optical cables is a hidden danger of transmission networking; It is mainly divided into the same cable and route (the same cable and route between two points, the same cable and route in the ring), the same pole (pipeline) and the same route near the pole (pipeline). Once the optical cable is in the same routing fault, it is easy to cause multiple transmission devices to be disconnected, thus interrupting a large number of home broadband, government-enterprise private lines and wireless base station services.
At the same time, the system integrates multi-channel fast switching devices, which can access 20 jumpers at the same time. Testers can use the intelligent terminal to switch quickly and remotely, so as to judge the same route conveniently and quickly and avoid major problems at the design end.
