Abstract :
We experimentally investigate the deleterious system effects due to polarization scrambling at frequencies of tens of kilohertz. In the presence of nonnegligible instantaneous polarization-dependent loss (PDL), transmission systems may suffer from performance variations due to the polarization-scrambling-induced intensity modulation. In particular, an instantaneous PDL of 2.6 dB can induce /spl sim/3 dB power penalty at a 29-dB optical signal-to-noise ratio.
