    • PURPOSE: A Fabry-Perot laser diode(FP-LD) simulation method and a device are provided to reduce calculation time by using a gain calculation formula used in a semiconductor optical amplifier. CONSTITUTION: A FP-LD simulation device applies the average of a calculated gain and a loss and phase change during a round-trip to the whole samples of injected light(S150). The FP-LD simulation device forms composite light by adding the whole samples of the injected light to the whole samples in which a phase change is applied. The FP-LD simulation device performs round-trip a number of times which the number of the whole samples of the injected light is divided into samples included in round-trip. The FP-LD simulation device outputs the loss and the phase change in the last round-trip by applying the same to the whole samples of the light performing the last round-trip.

CONSTITUTION: An optical detecting unit (131) receives an optical signal received from an optical network unit (ONU). The optical detecting unit converts the received optical signal into an electric signal. A PHF removes a noise by back reflection in the electric signal converted by the optical detecting unit. An arrayed waveguide grating (AWG) (200) performs the wavelength division distribution of the signal received through a first fiber. The AWG applies the distributed signal to the optical detecting unit.

    • PURPOSE: A noise suppressing apparatus and a wavelength division multiplexed-passive optical network (WDM-PON) system including the same are provided to amplify the high frequency band of a light source and to prevent the noise of a seed light generated from the light source. CONSTITUTION: An inverter unit (15) reverses the phase of an electric signal transformed from a transforming unit. A bandwidth compensating unit (17) amplifies a high frequency band of an electric signal generating a driving current which drives a light source. A light source driving unit (18) receives the electric signal of which the phase is reversed from the inverter unit. The light source driving unit generates a driving current which a light source drives through a signal of which a high frequency band is amplified by the bandwidth compensating unit. The light source driving unit supplies the generated driving current to the light source.
