Abstract

We experimentally demonstrate a monitoring method for determining misalignment between the I/Q data streams and between the data and pulse-carving in an 80-Gbit/s serial RZ- DQPSK transmitter. We show a dynamic-range of 8 dB for I/Q data misalignment and 6 dB for data to carver misalignment.
