what is cAMOS

CAMOS is built on advanced fiber-optic current sensing— bringing real-time electrical visibility to cable assets at scale.

CAMOS (Cable Advanced Management Optical System)  measures current by integrating FBG-based sensing at critical locations, capturing temperature, strain, and vibration across joints and terminations. Combined with distributed sensing technologies like DTS and DAS, CAMOS delivers a unified, continuous view of asset performance.

From insulation defects, poor jointing, unbalanced groundings, dynamic loads and oscillations, to cable health and transmission capacity monitoring, asset protection and precise fault localization, CAMOS transforms cables from passive infrastructure into intelligent, self-aware systems.

These measurements are captured in real time and processed through analytics engines that detect anomalies and fault signatures. Integrated dashboards and alert systems translate this data into actionable insights, enabling operators to monitor asset health, predict failures, and respond proactively across the cable lifecycle.
