KT Develops ‘DAS’ Platform to Detect Hazards Using Optical Fiber Cable

[Asia Economy Reporter Koo Chae-eun] KT has developed a 'Distributed Acoustic Sensing Platform' that can remotely detect sound waves from locations up to 40km away using optical fiber cables.

According to KT on the 19th, the Distributed Acoustic Sensing Platform is a solution that detects vibrations from heavy equipment construction around underground facilities such as gas pipes, heating pipes, and water pipes using KT's 790,000 km of communication optical fiber cables installed nationwide, and provides advance warnings. Previously developed acoustic sensing technology using optical fiber cables could only detect sound waves transmitted from a single optical fiber cable. For this technology to be applied on-site as a service platform, it was essential to devise a method to analyze various sound waves and improve accuracy.

To this end, KT developed the Distributed Acoustic Sensing Platform with a structure where multiple optical fiber cables simultaneously measure sound waves and transmit information. Additionally, the platform incorporates 'machine learning' technology that analyzes and learns the vibration characteristics of heavy equipment construction, and continuous field verification of the technology has been conducted to enhance the accuracy of sound wave detection.

Lee Jong-sik, Head of the Infrastructure Research Institute at KT Convergence Technology Institute (Senior Executive Director), said, "The Distributed Acoustic Sensing Platform is a technology that will bring changes to the current patrol inspection-based underground facility safety management system," adding, "We will continue research and development to improve accuracy and collaborate with local governments to develop and provide this as a warm service that ensures the safety of the public."
