Flexible WDM-PON with Nyquist-FDM and 31.25 Gbit/s per wavelength channel using colorless, low-speed ONUs

A remotely seeded flexible WDM network solution with 31.25 Gbit/s based on Nyquist sinc-pulses is demonstrated. The low-speed, colorless ONUs use remote heterodyne detection with electrical up- and down-conversion and SOAs for potential cost reduction.
