3.4 Detector Responsivity

INT-COM-1300 uses InGaAs PIN photodiodes. Figure 6 shows a typical responsivity
curve for this photodiode type.
This wavelength dependency affects the output signal amplitude. In order to
compensate this responsivity, the measured electrical signal must be multiplied by
the normalized wavelength dependent responsivity.
