title = "132.2-Gb/s PDM-8QAM-OFDM transmission at 4-b/s/Hz spectral efficiency",
abstract = "In this letter, we investigate 132.2-Gb/s polarization- division-multiplexed orthogonal frequency-division-multiplexing (PDM-OFDM) transmission at 25-GHz channel spacing. We show that the nonlinear tolerance is dependent on the OFDM symbol length. By using 14.4-ns-long OFDM symbols, 7 × 132.2-Gb/s transmission of PDM-OFDM at 4-b/s/Hz spectral efficiency is reported over 1300-km standard single-mode fiber.",
