TO-46 Package With Lens

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.

Operating Conditions: See table below. Fiber: Single-mode to multimode 62.5/125
