The Korea Rail Network Authority announced on the 30th that it will actively promote the construction project of IP-based optical transmission equipment (IP-MPLS) to enhance the safety of the nationwide railway optical transmission network and increase transmission capacity.
This project aims to build core infrastructure to efficiently manage the increasing network transmission traffic due to the full-scale introduction of various new technologies such as intelligent closed-circuit television (CCTV), Internet of Things (IoT), and digital twin in the railway sector.
The Rail Network Authority plans to invest a total of 123.6 billion KRW by 2028 to install optical transmission network equipment based on IP-MPLS technology at 1,025 stations of general and metropolitan railways nationwide and 187 high-speed railway stations. IP-MPLS is a technology that adds a short identifier called a label instead of an IP address in front of data transmitted through the communication network for high-speed processing.
In addition, to handle the increasing demand for long-distance, large-capacity traffic lines, the Rail Network Authority plans to place an order for the upgrade project of Dense Wavelength Division Multiplexing (DWDM) equipment within next year. DWDM is an optical transmission method that bundles multiple optical wavelengths and sends them simultaneously through a single optical cable.
Lee Seong-hae, Chairman of the Rail Network Authority, said, "We expect that this optical transmission network advancement project will transmit the rapidly increasing communication traffic without delay, further enhancing network safety," and added, "We will do our best to promote the project to timely provide the newly emerging large-capacity communication line demand."
