  • Wavelength conversion towards Rayleigh backscattering tolerant PONs via four-wave mixing in SOA-based ONUs 

    Schrenk, Bernhard; Lázaro Villa, José Antonio; Prat Gomà, Josep Joan (2010)
    Conference report
    Open Access
    Wavelength shifting in PONs with downstream signal remodulation is presented, allowing upstream transmission over trees with 25km feeder and 1:32 split with penalties <2dB, originally Rayleigh backscattering limited. ...
