FlexCoherent Modulation for the Terabit Age

Coherent super-channels have demonstrated a 30-fold increase in spectral efficiency and a 200-fold increase in operational scalability, as compared to classic 10 gigabit per second (10G) direct detection technologies. In this white paper, we explain how the latest wave of technology, based on higher-order modulation and transmitter-based compensation techniques, has developed, satisfying continuing increases in Internet demand.
