Fiber Optic Current Sensor Accuracy - SMB AI-Systems & High-Speed Interconnect [PDF]
A fiber-optic current sensor (FOCS) is a device designed to measure direct current. Utilizing a single-ended optical fiber wrapped around the current conductor, FOCS exploits the magneto-optic effect (Faraday effect). The FOCS can measure uni- or bi-directional DC currents up to 600 kA, with an accuracy within ±0.1% of the measured value.
