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
2015/7/16
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.
We propose and demonstrate a novel signal remodulation scheme using PolSK with high extinction-ratio. Error-free was achieved in a 20km reach 10Gb/s DWDM-PON without dispersion compensation.
