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...
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...
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.
