Wavelength division multiplexing-dense wavelength division multiplexed passive optical network (WDM-DWDM-PON) for long reach terrain connectivity

The wavelength division multiplexed and dense wavelength division multiplexed passive optical network (WDM-DWDM-PON) is designed and simulated to serve as long reach passive optical network (LR-PON). WDM-DWDM-PON network is simulated and analyzed upto the fiber reach of 100Km with and without dispersion compensation techniques. 16 Downstream WDM channels are modulated at the peak rate of 10Gb/s and 32 upstream DWDM channels are modulated at the rate of 2.5Gb/s. Optimum launch power and maximum reach of the fiber are calculated for each downstream and upstream case.
