A comprehensive systems model that retains the discrete nature of the output delay distribution in order to accurately characterize the pulse broadening due to Polarization Mode Dispersion (PMD) is developed in this thesis. PMD in optical channels has been a critical factor limiting high-speed data transmission over long distances in optical networks. PMD is a source of Inter Symbol Interference (ISI) and its impact increases with the transmission data rate. Since economical adaptive compensation schemes are currently unavailable, it is essential to characterize this impairment to completely understand its impact and develop effective countermeasures. An incremental approach has been developed to methodically grow the output DGD distribution of single mode optical fibers. It provides the flexibility to change individual beat segment delays and enables the simulation and characterization of the distributed and the deterministic effects of PMD. The model also accurately evaluates the impact of the PMD impairment on the performance of optical networks in terms of Q. Results from comparing performance penalties at 10G bus, 40G bps and 100 Gbps data rates of transmission are in agreement with published trends.
