Polarization-Dependent Loss Induced Penalties in PDM-QPSK Coherent Optical Communication Systems
21 March 2010
: We evaluate PDL-induced penalties in PDM-QPSK coherent systems with both lumped model and distributed model. We find the lumped model significantly over-estimates PDL penalties and PDM coherent systems can tolerate more PDL than single-polarization systems. © 2010 Optical Society of America OCIS codes: (060.2330) Fiber optics communications; (060.1660) Coherent communications; (260.5430) Polarization
