Comparison and analysis of codes for remodulation WDM-PON with adaptive code selection
Line codes Code efficiency WDM-PON Remodulation
2016/12/2
In a remodulation PON, the upstream signal quality can be improved when the downstream signal is coded. But low code efficiency may result in network congestion in downlink. Based on the downlink traf...
Time-Interleaved Phase Remodulation to Enable Broadcast Transmission in Bidirectional WDM-PONs without Additional Light Sources
Time-Interleaved Phase Remodulation Enable Broadcast Transmission Bidirectional WDM-PONs without Additional Light Sources
2015/5/21
Time-interleaved phase remodulation is proposed to realize broadcast transmission for WDM-PONs. Simultaneous transmission of 5-Gb/s bidirectional unicast data and broadcast data is demonstrated at the...
Optical Phase Remodulation for 10-Gb/s WDM-PON with Enhanced Tolerance to Rayleigh Noise
Fiber optics communications Networks
2015/6/8
A novel phase remodulation scheme for 10-Gb/s WDM-PON is proposed and demonstrated. Downstream DPSK signal with a reduced modulation depth facilitates upstream phase remodulation and Rayleigh noise...
Cost Efficient Directly Modulated DPSK Downstream Transmitter and Colourless Upstream Remodulation for Full-duplex WDM-PONs
Optical communications Phase modulation
2015/6/4
We implement a cost efficient 10.7Gb/s directly modulated DPSK transmitter in a bidirectional WDM-PON, which also remodulates the downstream phase encoded signal for 2.5Gb/s OOK upstream transmission.

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.
