We demonstrate a DSP-free 16-QAM/50GBd link based on independent transmit and LO frequency-stabilized ultra-narrow-linewidth SBS lasers, with ~40Hz integral linewidths and 7x10-14 fractional frequency stability. The low-BW optical-frequency-stabilized-PLL with 3x10-4 rad2 phase error operates within 1% of DSP and self-homodyne.
