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.

摘要： An optical amplifier comprises a wavelength tunable filter, one or more optical gain stages, and a controller for controlling a spectral profile of the wavelength tunable filter in response to a measured spectral characteristic of the amplifier. The controller may also control gain of the gain stage(s). The controller determines the filter spectral profile necessary to obtain a desired amplifier spectral characteristic. The spectral characteristic may, for example, be a power spectral output of the amplifier or a gain profile of the amplifier. The amplifier may incorporate a dispersion compensator. The controller may control a spectral profile of the wavelength tunable filter and gain of the dispersion compensator. A tunable fiber light source is also described.
