11.5-Gb/s OFDM Transmission over 640km SSMF using Directly Modulated Laser
OFDM Transmission SSMF Directly Modulated Laser

2015/7/30
We show 11.5-Gb/s optical OFDM transmission over 640km SSMF with directly modulated laser (DML) and direct-detection without dispersion compensation. DML can reduce the system complexity and cost.
Improved Nonlinear Tolerance of 112-Gb/s PDM-OFDM in Dispersion-Uncompensated Transmission with Efficient Channel Estimation
Nonlinear Tolerance PDM-OFDM Dispersion-Uncompensated Transmission Efficient Channel Estimation

We show numerically that the nonlinear tolerance of a 112-Gb/s PDM-OFDM signal, coherently received with a robust and efficient channel estimation method, is substantially improved by fiber dispersion...
Experimental Demonstration of Optical Colorless Direct-Detection OFDM Signals with 16- and 64-QAM Formats beyond 15 Gb/s

Both highly spectral-efficient direct-detection 15-Gb/s 64-QAM and 20-Gb/s 16-QAM OFDM signals are demonstrated. Negligible penalty is observed following 25-km SMF transmission.
Optical OFDM, a hype or is it for real?

In the last two years the number of optical OFDM papers has grown exponentially, but is this modulation format really a viable candidate for next generation fiber-optic transmission systems? In this p...
