How does the level of reflectivity affect the signal quality of the sensing system? What are the typical values?
Higher reflectivity in an FBG leads to a stronger reflected signal at the Bragg wavelength, which generally improves the signal-to-noise ratio and the overall signal quality of the sensing system. This is crucial for accurate and reliable measurements, especially in applications with long fiber runs or multiple sensors.
The typical reflectivity value for OFSCN® Fiber Bragg Gratings is 70%. It can be customized and is generally guaranteed to be greater than 20%. The reflectivity is also related to the grating length and can be customized within a certain range.
