Single chip 46 Gb/s DP-QPSK digital clock recovery and channel equalization performance in the presence of CD, PMD, and ultra-fast SOP rotation rates exceeding 20 krad/s

We demonstrate performance of a single chip 46 Gb/s coherent DP-QPSK transceiver. An OSNR penalty <;0.9 dB is shown for 56,862 ps/nm CD, and up to 100 ps DGD, 4000 ps
