متن کاملEvolution from TDM-PONs to Next-Generation PONs
An easy and efficient evolution method from a time-division multiplexing passive optical networks (TDM-PONs) to next-generation PONs is proposed and demonstrated. A single-type wavelength band combiner/splitter (WC) enables a simple and efficient evolution of TDM-PON maintaining the current PON infrastructure and wavelength plan. The feasibility of the proposed evolution architecture is shown b...
