Dual polarization in-phase and quadrature high speed submarine transmission with only two photodiodes, ADCs, MZMs and DACs

We propose a transceiver design capable of full-field modulation and detection with only two photodiodes, two analogto- digital converters, two Mach-Zehnder modulators and two digital-to-analog converters based on joint in-phase/quadrature generation and detection. Design is validated by long-haul transmission of dual-polarization 16QAM at 200 Gb/s.
