Openreach partners with Affinity Water and Lightsonic for fiber-optic leak detection trials
UK broadband provider Openreach has partnered with Affinity Water and Lightsonic to conduct trials using its fiber broadband network for water leak detection. The pilot utilizes Distributed Acoustic Sensing (DAS) technology developed by Lightsonic, converting Openreach's fiber optic cables into sensors to pinpoint leaks in Affinity Water's network. The successful trial has already prevented the loss of two megaliters of water in three months, demonstrating the potential for fiber infrastructure to address real-world challenges like water conservation.
