Abstract:
1. A method for determining a capacity of a wavelength division multiplexing (WDM) passive optical network (PON) at a computing device managing the WDM PON, the method comprising: abstracting a graphical representation of the WDM PON at a processor of the computing device by determining a structure of the WDM PON, the structure including one of a first architecture comprising ONUs equipped with lasers and optical line terminals (OLTs) equipped with receivers, and a second architecture comprising OLTs equipped with lasers and receivers and ONUs equipped with reflective semiconductor optical amplifiers (RSOAs); analyzing the abstracted graphical representation at the processor to determine an achievable rate region of the WDM PON, wherein the achievable rate region includes a set of admissible traffic rates for the WDM PON; and determining a maximum achievable rate region at the processor based on optimizing nodes and node relations of the WDM PON, wherein the nodes include one or more of full-range tunable lasers, limited-range tunable lasers, and/or specific tuning range lasers.
