Polarization Insensitive Subchannel-preserved Wavelength Conversion Polarization Multiplexed O-OFDM QPSK Signals Co-polarization Pumps
2015/5/21
By employing co-polarization dual-pump scheme, polarization insensitive and subchannel-preserved wavelength conversion of 432-Gb/s, dual-peak polarization-multiplexed O-OFDM QPSK signals has been real...
VCSEL-based Coherent Detection of 10-Gbit/s QPSK Signals Using Digital Phase Noise Cancellation for Future Optical Access Systems
Fiber optics communications Coherent communications
2015/6/5
We propose a VCSEL-based QPSK coherent system to be implemented for future access systems, using digital phase noise cancellation to achieve a coherent detection of 10-Gbit/s QPSK signals with a laser...
Transmission of 160-Gbit/s QPSK Signals on a Single Carrier over 1 , 000 km using Digital Coherent Receivers
Transmission QPSK Signals Single Carrier Digital Coherent Receivers
2015/7/20
We demonstrate 1,000-km transmission of a 160-Gbit/s QPSK signal, using a digital coherent receiver with the time-division demultiplexing function, and confirm the applicability of such a receiver to ...
