【 摘 要 】

References(7)We experimentally investigated DGD- and dispersion-tolerance of QPSK self-homodyne detection based on a polarization-multiplexed pilot carrier for both NRZ and RZ data formats. The results show that the tolerance is large enough to be used in deployed network systems. We also investigated receiver sensitivity penalty versus the ratio of pilot-carrier power to total optical power. The ratio had a detunable margin of as large as ±15% at around the optimum point of 50%.
