Opt Express. 2017 Oct 16;25(21):25046-25058. doi: 10.1364/OE.25.025046.

We propose to use adaptive bit loading based on time-domain hybrid QAM (TDHQ) to maximize the capacity of subcarrier-multiplexing (SCM) systems in meshed optical networks with cascaded reconfigurable optical add and drop multiplexers (ROADMs). Note that the capacity is...
