Experimental assessment of multi-dimensional modulation formats at high Baudrate for unrepeatered WDM systems

We experimentally assess a series of four multi-dimensional modulation formats for 100 Gbaud single-span unrepeatered multi-rate applications. We show the variation of maximum acceptable span loss for entropies between 1 and 2 b/S/pol, with a granularity of 0.25 b/S/pol.
