While the initial cost of fiber optic current sensors can be higher than traditional electrical sensors, their long-term benefits—including durability, reduced maintenance, and improved accuracy—often make them a more cost-effective solution in the long run. A fiber-optic sensor is a sensor that uses optical fiber either as the sensing element ("intrinsic sensors"), or as a means of relaying signals from a remote sensor to the electronics that process the signals ("extrinsic sensors"). Fibers have many uses in remote sensing. Think of it like a photoresistor, which changes its resistance based. Optical fiber sensors (OFSs) have emerged as essential tools in the monitoring of physical, chemical, and bio-medical parameters in harsh situations due to their high sensitivity, electromagnetic interference (EMI) immunity, and long-term stability. They also offer the promise of increased robustness with added functionality and lower operational costs. Building on field demonstrations.
