  • Fortistis: Split extension in dense passive optical networks by inline amplification with remote ASE-shaped pump delivery via colorless optical network units 

    Schrenk, Bernhard; Bonada Bo, Francesc; Lázaro Villa, José Antonio; Prat Gomà, Josep Joan (2010)
    Conference report
    Open Access
    A method for extending the customer density via ASE-pumped splitters in the tree in a WDM/TDM-PON is presented. The influence of Rayleigh backscattering in the feeder is faced, originally prohibiting any upstream transmission.
  • High customer density PON with passive amplification through distributed pump for > 1:1000 tree split

    A network architecture for tree-like passive optical networks (PONs) with high splitting ratios is proposed and experimentally demonstrated. Splits >1000 are shown to be feasible thanks to a noise-powered amplifier that ...
