Title

Optimization of Subcarrier Spacing of 400-Gb/s Dual-Carrier Nyquist PDM-16QAM in a Flexgrid Scenario

Abstract
For a 448-Gb/s dual-carrier 28-GBd Nyquist PDM-16QAM data signal we investigate experimentally the trade-off between inter-subcarrier crosstalk and tight optical filtering after passing through a wavelength selective switch at Flexgrid channel bandwidths of 75, 63 and 50 GHz.
