20 Gb/s Absolute Polar Duty Cycle Division Multiplexing-Polarization Division Multiplexing (AP-DCDM-PolDM) Transmission System

摘要

The performance of Absolute Polar Duty Cycle Division Multiplexing (AP-DCDM) over Polarization Division Multiplexing (PolDM) system is presented based on the simulation results, in order to double the capacity in optical fiber links. It is demonstrated that the spectral width occupied by 10 Gb/s RZ is 40 GHz whereas, this value can be reduced to 20 GHz over 2 channels of the proposed system. Simulations show that the maximum attainable dispersion-limited transmission distance for 20-Gb/s AP-DCDM-PoIDM data over standard single-mode fiber can be extended to 200 km for a 2-dB penalty.
