This paper presents a comprehensive review of AI-enhanced OFS technologies, encompassing both localized sensors such as fiber Bragg gratings (FBG), Fabry–Perot (FP) interferometers, and Mach–Zehnder interferometers (MZI), and distributed sensing systems based on Rayleigh . This has resulted in the creation of different types of sensors that can be used to monitor and control different environments, such as fire, water, temperature, and movement, among others. Optical fiber sensors at the micro/nanoscale have been integrated with microfluidic devices and planar photonic structures to develop all-optical chips, leading to high-speed acquisition, transmission, and processing of sensing signals.

The interference pattern relative to a reference waveform is an optical intensity value corresponding to the current magnitude. Utilizing a single-ended optical fiber wrapped around the current conductor, FOCS exploits the ( Interferometric fiber optic current sensors (FOCS) employ circularly polarized light traversing a closed loop path around an electrical conductor's current-generated magnetic flux, which reflects off a mirror. As FOCS are resistant to effects from magnetic or electrical field interferences, they are ideal for the measurement of electrical currents and high voltages in or other environme.
