3.5.1.6 Smart peak detection (SPD)
SPD allows the effective use of the high dynamic range offered by the
interrogator through the introduction of the individual measurement of an FBG
peak inside each configurable band.
MXFS considers a fixed threshold value of 3 dB, easing the configuration of the
device (
). Every wavelength value is calculated considering the area of
the FBG peak above half its power.
