Wavelength-Division Multiplexed Passive Optical Network for Reducing Degradation in Noise Characteristic of Wavelength-Locked Fabry-Perot Laser Diodes |
摘要 |
The present invention relates to a wavelength-division multiplexed passive optical network (WDM-PON) for reducing degradation in noise characteristic of a wavelength-locked Fabry-Perot Laser Diode (F-P LD). A WDM-PON for reducing degradation in a noise characteristic of a wavelength-locked F-P LD in accordance with the present invention comprises a central office (CO); a remote node (RN) being connected to the CO by a single mode fiber; and one or more optical network terminations (ONTs) being connected to the RN by one or more single mode fibers, respectively, wherein the CO comprises: a broadband light source (BLS) for generating light to be injected; a first wavelength-division multiplexing (WDM) filter for filtering for the injected light generated from the BLS and having a bandwidth wider than a bandwidth of the injected light in order to minimize a filtering effect; and one or more optical transceiver having one or more F-P LDs into which light being filtered by the first WDM filter is injected; and wherein the RN filters the injected light generated from the BLS and injects the filtered light into the one or more ONTs; and wherein the RN comprises a second WDM filter having a bandwidth wider than a bandwidth of the injected light in order to minimize a filtering effect.
