Abstract
We developed time-domain hybrid-modulation with adaptive symbolrates to optimize the reach and margin of WSS routed 400 Gb/s systems. Experimental comparisons show, that a DP-8QAM/16QAM hybrid format can outperform the benchmark DP-8QAM and DP-16QAM formats in distance when up to 18 WSS are incorporated.
