Abstract

This paper describes an analysis of directly modulated fiber-optic links using an active matching. Two MMICs amplifiers have been used as post-amplifier for transmitter and preamplifier for receiver. A large signal laser diode model is used as transmitter. An active matching is obtained between 50 (Omega) and both a low impedance of laser and a high impedance of photodiode. The simulated performances of fiber-optic links are presented in terms of gain, bandwidth, noise figure and distortion, in the range: 0.1 - 20 GHz. The noise figure has been reduced by using an active matching of fiber-optic links, also the bandwidth and gain have been increased.
