Demonstration of Signal Remodulation Long Reach Carrier Distributed Passive Optical Network using OFDM-QAM Signal
Signal Remodulation Reach Carrier Distributed Passive Optical Network OFDM-QAM Signal
2009/7/16
OFDM is a promising candidate for LR-PON. We study the possibility of using OFDM for signal remodulation in the LR-PON. Three different colorless ONU architectures are tested and compared.
Demonstration of High Spectral Efficient OFDM-QAM Long Reach Passive Optical Network
