DSP-complexity reduction of QAM-based coherent optical networks enabled by seed lightwave distribution

A new network scheme employing stable seed lightwave distribution is investigated for reducing QAM demodulation complexity. We perform 150 km seed distribution before 100 km WDM-PDM-64QAM transmission and achieve simple demodulation without phase estimation.
