WDM Transmission of 152-Gb/s Polarization Multiplexed RZ-16QAM Signals with 25-GHz Channel Spacing over 15× ×80-km of SSMF
Fiber optical communications Fiber optics links subsystems
2015/5/22
We demonstrate transmission of 20×152-Gb/s PolMux-RZ-16QAM at a channel spacing of 25 GHz (5.68 b/s/Hz) over 15×80-km spans of SSFM. Coherent detection was used to recover the transmitted data and we ...
117-Gb/s Optical OFDM Super-channel Transmission over 1200-km SSMF Using Direct Detection and EDFA-Only Amplification
Fiber optics communications Modulation
2015/5/22
With EDFA-only amplification, we successfully demonstrate the transmission of a 4-QAM, 117-Gb/s (100 Gb/s without overhead) DDO-OFDM super-channel over 1200-km SSMF with only 1-dB OSNR penalty. We als...
110-Gb/s Multi-band Real-time Coherent Optical OFDM Reception after 600-km Transmission over SSMF Fiber
Fiber optics links subsystems Coherent communications
2015/6/8
We demonstrate real-time reception of a 110-Gb/s multi-band OFDM signal after transmission of 600-km SSMF fiber and 400-ps differential-group-delay. The performance of 110-Gb/s CO-OFDM signal is chara...
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.
