When using 5G services on smartphones, data is transmitted through 5G repeaters, base stations, and telecommunications switching centers to servers containing content, where the processed data is then transmitted back to the customer's smartphone.

Since optical fiber lines transmit data between these equipment and switching centers, ensuring stability is critical, and when problems such as faults occur, it is essential to immediately identify their location and resolve them.

LG U+ announced on the 13th that it has begun applying an integrated optical fiber line monitoring system to its Seoul and metropolitan 5G networks that systematically manages optical fiber lines connecting 5G base stations, repeaters, and telecommunications switching centers, and enables real-time identification of fault locations and causes. Once deployment is completed in Seoul and the metropolitan area, the company plans to expand the system nationwide.

The optical fiber line monitoring system applied to secure 5G network quality can perform 24-hour monitoring of not only optical fiber lines between 5G repeaters, base stations, and telecommunications switching centers, but also wired network conditions used for internet and dedicated line services. Through optical signal wavelength analysis, the system can pinpoint any optical fiber line anomalies with an error margin of within 10 meters, regardless of where they occur.

Previously, when line breaks and other faults occurred in optical fiber lines, operators had to travel to switching centers with measurement equipment to measure optical signal values for each line individually, which took over tens of minutes. However, with the introduction of this optical fiber line monitoring system, individual optical fiber line conditions can be checked in real time, enabling rapid fault recovery.

As a result, LG U+ 5G customers will not only be able to enjoy 5G killer services such as AR and VR on networks with higher stability than 4G, but customers using IPTV and internet services are also expected to benefit from improved services.

LG U+ developed this system in cooperation with small and medium-sized enterprises Ubiquitous and Coweaver through win-win partnership.

Jo Chang-gil, Executive Managing Director of LG U+ in charge of backbone networks, stated, "Optical fiber lines are like the blood vessels of our body, with countless data streams from wired and wireless communication services continuously flowing through them. Systematic and efficient management and monitoring of optical fiber lines is essential not only for 5G services but also for enterprise dedicated lines and home internet service provision," adding, "Through the application of the optical fiber line monitoring system, we can now provide differentiated high-quality communication services in terms of network stability."
