ABSTRACT
We study the properties of electronic equalizers for optical communi-
cations systems and derive expressions that explain their behavior. We
use simulations to show the agreement with the theory developed.
1. INTRODUCTION
Electronic equalization is becoming increasingly important for mitiga-
tion of physical impairments in optical communication systems [1]. In
particular, it has been shown that it is effective in reducing the penalty
due to polarization mode dispersion (PMD), an important limiting fac-
tor for transmission rates and distances in installed terrestrial fiber sys-
tems. Experimental results at 10 Gbit/s use SiGe and GaAs technology
and report successful results for PMD mitigation [2] (also see [1] and
the references cited therein).
These equalizers are primarily based on the mean square error
