DISCRIPTION
PD8XX2 is an InGaAs avalanche photodiode suitable for
receiving the light having low noise, a wavelength band of
1000 to 1600nm. This photodiode features low noise, a high
quantum efficiency and a very small dark current and is
suitable for the light receiving elements for long-distance
optical communications.
