Home / Monitoring of underground optical cables
New advances in fibre optic sensing techniques are now ofering better visibility of buried cable operation and earlier warning of cable degradation issues endemic in the underground cable environment. Underground cable monitoring is crucial for maintaining reliability and preventing failures caused by environmental and mechanical threats. By detecting issues early, it enables proactive maintenance, reducing the risk of service disruptions and costly repairs. This paper sets out how the power sector can capitalise on these advances after first considering.
