This device consists of a PIN photo-
diode and a transimpedance amplifier
assembled in a TO-46 package. It is
designed for short-distance ATM up
to 155 Mbps. The preamplifier’s lin-
earity and absence of automatic gain
control makes it ideal also for analog
applications and applications with
bursty signals. Its double-lens optical
system is designed for single-mode
fiber as well as for multimode fiber
with core diameter up to 62.5µm.
