RESUMO

Signal distortion induced by Polarization Mode Dispersion and Polarization Dependent Losses in long-distance high-capacity optical transmissions is discussed from the viewpoint of the statistical behavior of the bit error rates. Pure first order PMD effects, pure PDL effects and combined PMD/PDL effects in digital transmissions were evaluated through power penalties measurements. It is show that PDL strongly enhances PMD effects and that the BER fluctuations may be much higher than those induced by pure PMD or pure PDL. The results obtained indicate that the chirp of the source plays an important role in the combined PMD-PDL effects.
