The very high speed and low capaci-
tance of this GaAs PIN Photodiode
makes it ideal for datacom and general
purpose applications. Its double-lens
optical system is designed for single-
mode fiber as well as for multimode
fiber with core diameter up to
62.5m. And a reverse voltage of only
5 Volts makes interfacing to a pream-
plifier easy.
