The Impact of the Combined 8-QAM and QPSK Subcarrier Modulation for Coherent Optical OFDM
8-QAM QPSK Subcarrier Modulation OFDM
2015/5/15
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...
Polarization-Multiplexed Multilevel LDPC-Coded Modulation for Optical Communication Systems
Polarization-Multiplexed Multilevel LDPC-Coded Modulation Optical Communication Systems
2015/7/17
Polarization-multiplexed coded-modulation, with joint coherent MAP detection and soft-iterative decoding, which considers independent symbols transmitted over both polarizations as a super-symbol is p...
160 Gbit/s OTDM System Based on 40 GHz Optical Pulses Generated Using Simultaneous Two-Arm Modulation of a Mach-Zehnder Modulator
OTDM System Optical Pulses Generated Mach-Zehnder Modulator
2015/7/17
Bit-error-rate free performance of 160 Gbit/s OTDM data based on 1.9 ps 40 GHz optical pulses generated by simultaneous two-arm modulation of a Mach-Zehnder intensity modulator has been demonstrated.
A statistical assessment of the nonlinear cross-polarization modulation is presented. The resulting distribution of the states of polarization is derived while accounting for various properties of the...
