  • Can a fiber optic sensor transmit two signals

    Can a fiber optic sensor transmit two signals

    Once a light signal is transmitted throughout the interferometer, next the light signal will divide into two signals where one signal is exposed to the sensing environment and the other one is isolated from the sensing environment, which is used as a reference. A fiber optic transceiver (also called an optical transceiver) is a compact module that both transmits and receives data signals through optical fibers. 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. At the heart of this technology lies an essential component called the optical fused coupler. This signal can then be measured by an instrument or interpreted by a user. For example, a thermocouple is a sensor that detects.
