Description The very high speed and low capacitance of this GaAs PIN Photodiode makes it ideal for datacom and general purpose applications. Its double-lens optical system collects power from fibers with up to 100mm without loss in responsivity and a reverse voltage of only 3.3 Volts makes interfacing to a preamplifier easy.
