Single-wavelength, single-polarization, single- photodiode kramers-kronig detection of 440-Gb/s entropy-loaded discrete multitone modulation transmitted over 100-km SSMF

We demonstrate 100-km standard single-mode fiber (SSMF) 1550-nm dispersion-uncompensated transmission and single-photodiode Kramers-Kronig direct detection of 440- Gb/s line rate and 279 Gb/s net-data-rate using discrete multitone modulation with entropy- and power-loaded probabilistically shaped subcarriers generated by digital band interleaving.
