Nyquist Subcarriers
Delivering World-record Optical Performance Pioneered by Infinera
Nyquist subcarrier technology divides a single high-baud-rate wavelength (carrier) into multiple low-baud-rate subcarriers. In Infinera’s ICE6, our second-generation subcarriers are enhanced with per-subcarrier probabilistic constellation shaping (PCS) and dynamic bandwidth allocation. The results are even higher capacity-reach for high-baud-rate transmission on a single fiber.

Highlights

Pioneered by Infinera
Infinera was the first company to implement subcarrier transmission in ICE4, and these capabilities have been further enhanced in ICE6.

Mitigate high baud rate penalties
ICE6 operates up to 100 GBd and beyond, and using multiple subcarriers allows us to mitigate the penalties caused by noise-induced chromatic dispersion compensation.

Per-subcarrier PCS
Infinera’s PCS is implemented on a per-subcarrier basis to allow highly granular transport of data payloads while minimizing optical impairment penalties.

World-record trans-Atlantic performance
While subcarriers excel in terrestrial networks, ICE6 has also demonstrated world-record trans-Atlantic performance with up to 28 Tb/s fiber capacity and 650 Gb/s wavelength data rates.
