72×100Gb/s transmission over transoceanic distance, using large effective area fiber, hybrid Raman-Erbium amplification and coherent detection

Abstract

100Gb/s channels are transmitted over 7,040km. After propagation across eighty-eight 80km-long sections of large effective area fiber, separated by Raman-assisted erbium repeaters, demodulation of PDM-QPSK waveforms is performed with digital processing in a coherent receiver.
