Description

AI-based active optical fiber management system

The present invention relates to an optical path management system, and more particularly, by preventing optical path errors and losses, and automatically securing the most up-to-date data on the optical line, and the optimization solution for optical fiber search and management when working with the optical line. It is about an AI-based active optical fiber management system to provide an optimization solution for the design of the work line and a solution for the occurrence of line errors.

In general, optical cables are widely used in high-speed communication networks because they have lower loss and higher bandwidth than copper wires. However, optical cables have a problem in that reliability is somewhat weak compared to copper wires due to low mechanical properties. That is, the optical cable is easier to cut compared to the copper wire, and there is a problem in that communication is impossible when it is bent at a certain angle or more. Therefore, when a failure occurs in an optical cable, operators who have built an optical communication network quickly identify the failure point in order to restore the optical line and put manpower to the failure point.

In addition, it takes a lot of time to find and connect suitable cables from 144 optical lines during the work of finding and connecting the incoming and outgoing cables required for the optical fiber work of the enclosure.

On the other hand, a technique for checking whether the optical path is faulty through an optical meter has been disclosed. Specifically, the optical measuring device transmits OTDR (OPTICAL TIME DOMAIL FDFLECTOMETER) pulses to a plurality of optical termination devices connected to the distribution device, and analyzes a plurality of OTDR pulses that are reflected from the plurality of optical termination devices and return in sequence, Analyze for abnormalities.

In addition, 12 optical cables are divided into a total of 12 units as one unit and managed, and the 12 optical cables have different colors for easy identification.

However, there is a problem that the operator has to check each optical cable one by one, and it takes a long time to work.

In addition, even if an optical cable is found and connected, there is a problem in that the serial number has to be manually drawn up to the final installation place, which also causes an error.

An object of the present invention to solve the above problems is to attach an RFID tag to each unit of the optical cable to facilitate the operation, measure the data lost when measuring the optical fiber, and then accumulate the data by sending the server to the flow rate of the lost data. It is converted into low-volume data after being converted into low-volume data, and when a late worker recognizes an RFID tag when working with an optical line, real-time data about the optical path can be checked on-site. The purpose of this is to provide an AI-based active optical fiber management system that provides a blueprint of the optical fiber and provides a solution for reducing work time and solving problems when a problem arises in the construction of an optical fiber.

The AI-based active optical path management system of the present invention for achieving the above object includes an optical path to which an RFID tag is attached; an optical fiber collimator for identifying a specific optical fiber from among the optical fiber cables; a splicer for connecting the optical cable of the optical path and another cable, and comprising a display unit, a sensor unit, and a communication unit; an optical power meter including a short-distance communication unit capable of measuring optical power at the final RN of the cable fused by the splicer and transmitting the measured data; A terminal capable of communicating with the optical fiber, optical fiber collator, fusion splicer, and optical power meter; and a central server that stores all data authorized from the terminal and stores GIS data and optical fiber data; Configurable including can

In addition, first, the terminal automatically generates a line number based on AI using the connected cable and the optical fiber data and GIS data of the central server and provides it to the user; Providing a user with a fusion environment with a low loss value based on AI in order to lower the loss value during fusion with a fusion splicer; recognizing the RFID tag attached to each optical cable unit to check optical path information; measuring the optical power value of each of the optical cables to be fused with an optical fiber collator, reconfirming whether the optical cable is oblique, transmitting the signal to a terminal, and providing an output; transmitting a loss value generated while splicing the optical cable to be spliced with a splicer to a terminal, and storing the loss value as accumulated data in a central server; Based on the automatically generated sequence number, all fusions are completed, measuring the optical power value with an optical power meter at the final RN, transmitting the input optical power value to the terminal, and outputting and providing the optical power value; The information of each optical cable is transmitted to the terminal, and when a defect occurs in the optical line, an AI-based solution is provided to the user, and the solution is to use the accumulated data inputting the solution for the accumulated defect; can
