The multistage wavelength division multiplexed passive optical network (WDM-PON) with multiple remote nodes (RN) can accommodate widely spread subscribers efficiently and it increases the channel usage. We implemented a multistage RN using band add-drop filters and it was applied to a wavelength-locked Fabry-Petor laser diode based gigabit WDM-PON.
