  2. Fiber-optic current sensor - Wikipedia

    en.wikipedia.org/wiki/Fiber-optic_current_sensor

    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, [1] FOCS exploits the magneto-optic effect (Faraday effect). [2] The FOCS can measure uni- or bi-directional DC currents up to 600 kA, with an accuracy within ±0.1% of the measured value.

  3. Fiber-optic sensor - Wikipedia

    en.wikipedia.org/wiki/Fiber-optic_sensor

    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").

  5. Distributed acoustic sensing - Wikipedia

    en.wikipedia.org/wiki/Distributed_acoustic_sensing

    In Rayleigh scatter-based distributed fiber optic sensing, a coherent laser pulse is sent along an optic fiber, and scattering sites within the fiber cause the fiber to act as a distributed interferometer with a gauge length approximately equal to the pulse length. The intensity of the reflected light is measured as a function of time after ...

  6. Submarine communications cable - Wikipedia

    en.wikipedia.org/wiki/Submarine_communications_cable

    In the 1980s, fiber-optic cables were developed. The first transatlantic telephone cable to use optical fiber was TAT-8, which went into operation in 1988. A fiber-optic cable comprises multiple pairs of fibers. Each pair has one fiber in each direction. TAT-8 had two operational pairs and one backup pair.

    FFT was established in Melbourne, Australia in 1994 as a research and development company. In 1998, in response to the demand for cost-effective, optical fiber sensors to protect large perimeters, buried pipelines and physical network communication links, FFT developed technology that could pinpoint the location of intrusions over many miles of deployed optical fiber.

  8. Distributed temperature sensing - Wikipedia

    en.wikipedia.org/wiki/Distributed_temperature...

    The temperature measuring system consists of a controller (laser source, pulse generator for OTDR or code generator for Code Correlation or modulator and HF mixer for OFDR, optical module, receiver and micro-processor unit) and a quartz glass fibre as line-shaped temperature sensor. The fibre optic cable (can be 70 km in length [5]) is passive ...

  9. Optical power meter - Wikipedia

    en.wikipedia.org/wiki/Optical_power_meter

    An important part of an optical power meter sensor, is the fiber optic connector interface. Careful optical design is required to avoid significant accuracy problems when used with the wide variety of fiber types and connectors typically encountered. Another important component, is the sensor input amplifier.
