Hybrid Modulation Formats Outperforming 16QAM and 8QAM in Transmission Distance and Filtering with Cascaded WSS
15 June 2015
We developed time-domain hybrid-modulation with adaptive symbol-rates to optimize the reach of WSS routed 400 Gb/s systems. Experimental comparisons show, that a 8QAM/16QAM hybrid format can outperform the benchmark 8 QAM and 16 QAM formats in distance when up to 18 WSS are incorporated.
