The Impact of the Combined 8-QAM and QPSK Subcarrier Modulation for Coherent Optical OFDM
8-QAM QPSK Subcarrier Modulation OFDM
2011/5/15
We investigated the optimized signal condition of the combined 8-QAM and QPSK subcarrier modulation for optical OFDM. The performance improvement was confirmed by WDM transmission experiments with the...
Experimental Demonstration of 16-QAM Transmission with a Single Dual-Drive Mach-Zehnder Modulator
Dual-Drive Mach-Zehnder Modulator 16-QAM Transmission
2011/5/15
10-Gbit/s 16-QAM transmission over 160 km with a single dual-drive Mach-Zehnder modulator was experimentally demonstrated. We achieved BER<10 -9 in a BtB condition and <10 -7 after the transmission. E...
