Coherent 40 Gb/s Transmission with High Spectral Efficiency Over Transpacific Distance
Coherent 40 Gb/s Transmission High Spectral Efficiency
2011/5/20
We experimentally study the reach of coherent 40 Gb/s PDM RZ QPSK transmission at several spectral efficiencies. Transpacific transmission distance at 3.2 bits/s/Hz and record SE-distance product at 2...

Spectrum-Efficiency Bandwidth-Variable Optical OFDM Transport Networks
2010/6/10
We investigated the high spectrum efficiency property of the bandwidth-variable optical OFDM (BV-OOFDM) transport networks. In contrast to mixed-line-rate (MLR) networks, BV-OOFDM enables flexible all...
10 × 112-Gb/s PDM 16-QAM Transmission over 1022 km of SSMF with a Spectral Efficiency of 4.1 b/s/Hz and no Optical Filtering

2009/7/16
Ten 25-GHz-spaced wavelength-division-multiplexed channels using 112-Gb/s polarization-division-multiplexed 16-QAM are transmitted over 1022 km of standard single-mode fiber. Owing to electrical-drive...
