Abstract
We experimentally demonstrate 770-Gb/s (77-Gbd PDM-32QAM) transmission on a single wavelength using an indium phosphide dual polarization IQ modulator over 320 km of standard single mode fiber, which is suitable for low-cost metro networks and datacenter interconnects. Moreover with the same setup, we also demonstrate transmissions of 84-Gbd polarization division multiplexed (PDM)-16QAM and 84-Gbd PDM-8QAM signals over 960 and 1980 km distances, respectively, for regional and long-haul networks.
