Abstract
Signal remodulation is considered to lower the cost of future WDM-PON by wavelength reuse. We propose and demonstrate a signal remodulation scheme using PolSK modulation in both downstream and upstream signals for "colorless" WDM-PON. High extinction-ratio can be achieved in both downstream and remodulated upstream signals; hence power sacrifice of using residual optical power in downstream signal for the upstream remodulation is eliminated. Split-ratio analysis is performed for the hybrid WDM-TDM architecture. Results show that the proposed scheme could be a potential candidate for next generation wavelength reuse WDM-TDM PON.
