Nyquist Subcarriers

World-record Spectral Efficiency Pioneered by Infinera​

Nyquist subcarrier technology divides a single high-speed wavelength into multiple efficient low-baud-rate subcarriers. The technology is enhanced with granular subcarrier control, allowing tighter spectrum packing. The results are even higher capacity-reach on a single fiber, proven to deliver world-record-breaking capacity.​
