Generation of 5-Gbps QPSK Signal using Directly Modulated RSOA for 100-km Coherent WDM PON
Fiber optics links subsystems Coherent communications
2011/5/22
We generate the QPSK signal by utilizing the chirp characteristics of the directly modulated RSOA for the high-speed coherent WDM PON. In addition, we demonstrate the error-free transmission of the 5-...
Real-Time Evaluation of Optical Nonlinear Effects on 112Gbps PM-QPSK Signal in Dispersion Managed Links
Optical Communications Coherent Communications
2011/5/20
We demonstrate the impact of nonlinear effects on dispersion managed links with a FPGA-based 112Gbps real-time receiver. We clarify that PM-RZ-QPSK provides superior robustness, whereas PM-NRZ-QPSK of...
432Gbit/s O-OFDM QPSK signal transmission over 400km SMF-28 with EDFA-only amplification
O-OFDM QPSK signal transmission
2011/5/15
432Gbit/s O-OFDM QPSK transmitter has been proposed and experimentally demonstrated.After transmission over 400km standard single-mode fiber (SMF), the measured BER is smaller than 2 ×10 -5 .
Compact and Broadband Coherent Receiver Front-End for Complete Demodulation of a 1.12-Terabit/s Multi-Carrier PDM-QPSK Signal
Broadband Coherent Receiver Multi-Carrier PDM-QPSK Signal
2009/7/20
We report a compact coherent receiver front-end consisting of an integrated 4x40 arrayed-waveguide-grating array following a polarization-diversity hybrid for complete demodulation of a 1.12-Tb/s mult...
