Abstract

The distribution and performance implications of filtered interferometric crosstalk in optical networks is theoretically and experimentally studied. The probability density function is estimated by using a maximum entropy approach based on analytically derived statistical moments. The theoretical results are confirmed by relevant experimental data obtained from an amplitude shift keying direct detection (ASK/DD) system using directly, and externally modulated light sources. Power penalties are measured for both types of source modulation. The experimental results are in good agreement with theory.
