Transmission Experiment Using a Coupled-Cavity VCSEL for Radio Frequency Conversion
Transmission Experiment Coupled-Cavity VCSEL Radio Frequency Conversion
2015/5/21
We perform a transmission experiment using a coupled-cavity VCSEL and demonstrate its unique ability for radio frequency conversion. For a short-reach link, the system performance is governed by the d...
Comparison of Pulse Shapes in a 224Gbit/s (28Gbaud) PDM-QAM16 Long-Haul Transmission Experiment
Fiber optics communications Phase modulation
2015/5/20
We investigate the effectiveness of RZ50 versus NRZ in a 224Gbit/s PDM-QAM16 transmission. Record distances of 2000km and 1520km are reported for single- and 3-channel transmission over SMF links with...
Reciprocal Acoustic Transmission Experiment in Shallow Water
Reciprocal Acoustic Transmission Experiment Shallow Water
2009/8/19
Development of coastal acoustic tomography is carried out as a long term measurement technique to get shallow water information. Since sound is propagated with reflection at sea bed and sea surface, i...
The Impact of DWDM Channel De-correlation Method in Optical PSK Coherent Transmission Experiment
DWDM Channel Optical PSK Coherent Transmission Experiment
2015/7/20
In a DWDM PSK coherent experiment, the even/odd channel de-correlation overestimates XPM phase noise by two and underestimates its autocorrelation length by 40%, which suggests that enhanced de-correl...
100Gb/s WDM NRZ-PM-QPSK Long-Haul Transmission Experiment over Installed Fiber Probing Non-Linear Reach With and Without DCUs
WDM NRZ-PM-QPSK Transmission Experiment Installed Fiber Probing Non-Linear Reach Without DCUs
2015/7/15
We present an experiment of WDM 100Gb/s coherent NRZ-PM-QPSK transmission over 16 spans of installed SSMF. We used variable span loss, with and without optical dispersion compensation, to investigate ...
Australia-Bermuda Sound Transmission Experiment（1960）Revisited
Australia-Bermuda Sound Transmission Experiment Bermuda hydrophones
2009/1/6
Detonations at the depth of the sound channel axis off Perth, Australia were recorded on Bermuda hydrophones at a 178°.2 range (180° is antipodal). The analysis by Shockley et al. of this 1960 transmi...
Transmission Experiment using Installed Submarine Cable for System Upgrade with RZ-DPSK
Installed Submarine Cable System Upgrade RZ-DPSK
2015/8/4
We have shown that a capacity of the transpacific system designed to support 8 x 2.5 Gbit/s can be increased to a factor of eight by using 16 x 10 Gbit/s RZ-DPSK in transmission experiments using a de...
160 Gbit/s-200 km Field Transmission Experiment Using a Time-Domain Optical Fourier Transformation Technique with a Large PMD
Time-Domain Optical Fourier Transformation Technique Large PMD
2015/8/4
160 Gbit/s-200 km DPSK field transmission using time-domain optical Fourier transformation was demonstrated with a large PMD. Error-free performance with only a 1.5 dB power penalty was achieved.
