Abstract :
We propose and demonstrate a migrating scheme from TDM-PON to WDM-PON using downstream differential-phase-shift-keying (DPSK) and upstream wavelength-shifted-amplitude-shift-keying (WS-ASK) signals. An optical-filter is pre-installed in the optical-networking-unit (ONU) for DPSK demodulation. Rayleigh-backscattering is also mitigated.
