Abstract
We demonstrate an endless optical domain polarization demultiplexing scheme that was realized in a 96 Gbaud-PS-16QAM coherent transmission system to alleviate the data processing pressure of the DSP in the receiver. It can be effectively employed in the 140 km fiber link (Metro DCI) and extended to the 2000 km optical fiber networks (Long haul DCI or backbone networks transmission). It can track 10 krad/s state of polarization (SOP) changes following Rayleigh distribution which is the general statistical case for real fibers. The proposed method has a noise tolerance equivalent to that induced by a 2000 km transmission, with OSNR as low as 20 dB, with a maximum PMD of 4 ps and a mean DGD of 2.5 ps.
