Real-time FPGA-based Coherent Optical Receiver for 1 Gsymbol/s, 64 QAM Transmission
Coherent communications Fiber optics communications
2015/5/25
We demonstrated the first time real-time FPGA-based coherent optical receiver for a 64 QAM transmission. Error free performance (BER < 1x10 -12 ) was achieved under a back-to-back condition and the BE...
140 Gbit/s Coherent Optical Transmission over 150 km with a 10 Gsymbol/s Polarization-Multiplexed 128 QAM Signal
Fiber optics communications Coherent communications
2015/6/8
We demonstrate a 140 Gbit/s coherent optical transmission over 150 km with a polarization-multiplexed 10 Gsymbol/s, 128 QAM format in a 20 GHz bandwidth. Error-free 120 Gbit/s-150 km transmission is a...
Pre-compensation for the Effects of Cascaded Optical Filtering on 10 Gsymbol/s DPSK and DQPSK Signals
Pre-compensation Cascaded Optical Filtering Gsymbol/s DPSK DQPSK Signals
2015/7/17
The effects of cascaded optical filtering on 10 Gsymbol/s DPSK and DQPSK signals are mitigated by pre-compensation based on the use of digital signal processing to generate the drive signals for a dua...
ISI Pre-equalization in a Vector Modulator for 5 Gsymbol/s 64-QAM
ISI Pre-equalization Vector Modulator Gsymbol/s
2015/7/31
We investigated the performance of electronic pre-equalization to compensate for ISI caused in a vector modulator for 5 Gsymbol/s 64QAM. Drastic improvement in the constellation was experimentally con...
Frequency Division Multiplexed 1 Gsymbol/s, 64 QAM Coherent Optical Transmission with a Spectral Efficiency of 8.6 bit/s/Hz
Frequency Division Multiplexed QAM Coherent Optical Transmission Spectral Efficiency
2015/7/30
We have successfully transmitted a three-channel frequency division multiplexed 1-Gsymbol/s, 64 QAM coherent optical signal over 160-km with a 1.4-GHz spacing. The spectral efficiency reaches as high ...
