In this work, we experimentally implement an adaptive polarization demultiplexing (PolDemux) technique based on the representation of the state of polarization (SOP) of the signal in the Stokes space in bidirectional ultra-dense wavelength-division-multiplexed (U-DWDM) optical metro networks. BER measurement is used to assess the quality of DP-QPSK and DP-16QAM signals in back-to-back and after 80...
In this paper, we firstly review the progress in ultra-dense wavelength division multiplexing passive optical network (UDWDM-PON), by making use of the key attributes of this technology in the context of optical access and metro networks. Besides the inherit properties of coherent technology, we explore different modulation formats and pulse shaping. The performance is experimentally demonstrated...
