Demonstration of Baud-Rate-Variable and Channel- Spacing-Tunable Demultiplexing of 10-40-Gbaud OFDM Subcarriers using a Multi-Tap Optical DFT
Fiber optics links subsystems Nonlinear wave mixing
2011/5/25
We experimentally demonstrate a tunable and reconfigurable optical DFT to demodulate 10-40-Gbuad OFDM with 2/3/4 subcarriers at 20/40GHz frequency spacing. Average power penalty of ~7 dB at BER of 10 ...
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
2011/5/22
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 ...
Transmission of 42.8-Gb/s Polarization Multiplexed RZ- QPSK DWDM Signals over 3900 km with 12.5-GHz Channel Spacing and Coherent Detection
Fiber optical communications Fiber optics links subsystems
2010/6/9
We have experimentally demonstrated 42.8Gb/s DWDM transmission over 3900km SMF-28 with 12.5-GHz channel spacing and coherent detection. Eight polarization-multiplexed-RZ-QPSK signals have been success...
A Novel Optical Fast OFDM with Reduced Channel Spacing Equal to Half of the Symbol Rate Per Carrier
Fiber optics communications Modulation
2010/6/8
We propose a novel discrete-cosine-transform based optical fast OFDM (FOFDM) to reduce the channel spacing to half of the symbol rate per carrier, and numerically evaluate the performance of 20Gbaud P...
Multi-Rate (111-Gb/s, 2x43-Gb/s, and 8x10.7-Gb/s) Transmission at 50-GHz Channel Spacing over 1040-km Field-Deployed Fiber
Multi-Rate Transmission Channel Spacing over Field-Deployed Fiber
2008/7/30
111-Gb/s transmission combined with 2x43-Gb/s and 8x10.7-Gb/s on a 50-GHz grid over 1,040-km field fiber and two ROADMs is demonstrated, showing the feasibility of 100G overlaying existing 10G/40G com...
