4.28-Tb/s (10 x 428-Gb/s) transmission over 2400 km using ETDM 107-Gbaud PDM QPSK
17 March 2013
We demonstrate all-electronically multiplexed polarization multiplexed 107-Gbaud quadrature-phase-shift-keyed (PDM-QPSK) transmission over 2400 km using coherent detection based on a real-time oscilloscope with 63-GHz electronic bandwidth, sampled at 160 GS/s. Ten WDM channels are transmitted on a 120-GHz grid for a spectral efficiency of 3.3 b/s/Hz.
