Innovation in Underground Optical Cables

Home / Innovation in Underground Optical Cables

An interdisciplinary team of researchers led by the CONNECT Research Center, based at Trinity College Dublin, is developing sensors to detect and ultimately analyze tiny changes in light as it travels through existing underground and seacoast fiber-optic cables (see video). This study evaluates key trenchless methods, including Horizontal Directional Drilling (HDD). HDD is a trenchless method that enables the installation of underground utilities—such as fiber optic cables—beneath obstacles like roads, rivers, and developed urban landscapes. The Underground Optical Cables Market is demonstrating a robust growth outlook, signaling strong confidence across industries worldwide.
