RESUMO

The polarization effects that cause limitations in optical communications are essentially the Polarization Mode Dispersion (PMD), the Polarization Dependent Loss (PDL), and the Polarization Dependent Gain (PDG). These effects can appear either isolated or in combinations, generating signal distortion. These effects were first investigated individually under different experimental situations and then combined effects were studied. A new technique for measuring the power penalties corresponding to these effects was proposed. The combined effects of PMD and PDL in PMD emulators were evaluated and quantified. Thumb rules for the manufacture of PDL-free emulators were proposed. The effects of PMD and PDG originated from Raman amplification were also studied and compared with theoretical predictions.
