Monolithic integrated amplifiers for 400 Mbit/s optical repeater

Abstract
Introduction of monolithic integrated circuit technology to high bit rate optical repeater is studied. Monolithic integrated amplifiers are realised for a 400 Mbit/s optical repeater such as a preamplifier, AGC amplifier and postamplifier, using advanced silicon bipolar process technology. An equalising amplifier with four monolithic amplifiers got 66 dB maximum gain, 35 dB variable gain and 350 MHz band-width with 550 mW power consumption.
