• Fiber optic sensor principle
    Fiber optic sensor principle
    Fiber optic sensors are a new type of sensor that has evolved along with the development of fiber optic and fiber optic communication technologies. The fiber-optic sensor is corrosion-resistant, has little influence on the medium, and has strong anti-electromagnetic interference capability. Compared with the traditional sensors, the fiber-optic sensor uses light as a carrier fo...

  • Erbium doped fiber amplifier (EDFA)
    Erbium doped fiber amplifier (EDFA)
    The erbium-doped fiber amplifier (EDFA) is a medium that uses helium ions to achieve energy conversion. The energy amplification window has an operating wavelength window of 1 550 nm and a width of 50 am, which is consistent with the low loss window of the fiber. The energy injection window is 980 nm and 1 480 nm.
