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.
