Abstract
Simultaneous transmission of two polarization-division-multiplexing four-level pulse-amplitude-modulation (2 × PDM-PAM4) signals is proposed, and a simplified receiver is used for demultiplexing two data streams. Experimental results at 160-Gbit/s show that the power penalty of each data stream is ~0.4-dB (back-to-back) and ~1-dB (25-km transmission) compared with the single PDM system. Furthermore, the stabilization of the proposed scheme is investigated. The BER fluctuation is <0.5-dB at a polarization scrambling rate up to 1417.5-deg/s.
