    Fibre Bragg Grating YOSC-FBG-15xx

    A wavelength reflecting device made by using ultraviolet light and phase mask engraved on an optical fibre. YOSC adopts advanced production processes to mass-produce fibre Bragg gratings of various wavelengths in the C+L band.
    Applications
    • The core sensitive units of various FBG sensors
    • Monitoring of electricity, petrochemicals, civil engineering, tunnels, temperature, strain, pressure, etc
    Characteristics
    • Stable performance, high reflectivity, and small 3dB bandwidth
    • High precision, strong stability, and excellent reliability
    • Customizable
    • High SLSR
