102.3-Tb/s (224 × 548-Gb/s) C- and Extended L-band All-Raman Transmission over 240 km Using PDM-64QAM Single Carrier FDM with Digital Pilot Tone

Abstract

We demonstrate 102.3 Tb/s transmission over 3×80 km of PSCF by employing 548-Gb/s PDM-64QAM single-carrier frequency-division-multiplexing (SC-FDM) signals with pilot tone and 11.2-THz ultra-wideband low-noise amplification in the C- and extended L-bands.
