Long haul and high speed optical networks using dual polarization 2-band OFDM CS-NRZ-DQPSK signal
Résumé
In this paper, we propose to demonstrate a long haul and high speed network based on a 2 band Orthogonal Frequency Division Multiplexing (OFDM) signal and a Carrier Suppression (CS) Non Return to Zero (NRZ) Differential QPSK non-coherent modulation format. We considered 112 Gbit/s per channel bit rate and multiplexed 32 channels following the 100 GHz WDM ITU grid. We demonstrate a transmission over more than 3000 km with a BER bellow 10-3
