摘要： A method and apparatus for controlling a wavelength tuning of an optical source in an optical communication system. An operating temperature of an optical source is controlled and monitored to shorten a wavelength tuning time of the optical source generated in an optical source generator. When the current operating temperature reaches a final target temperature, an operating current is supplied to the optical source generator, and transmission of the operating current to the optical source generator is controlled and monitored. When the operating current reaches a final operating current, the wavelength tuning of the optical source is terminated. The operating temperature is adjusted by distinguishing between a smaller amount of temperature change and a larger amount of temperature change to prevent oscillation at the point of reaching the final target temperature, thereby minimizing the time taken for the output wavelength tuning.

摘要： A device for compensating for PMD occurring in a transmission optical fiber in an optical transmission system. An output beam from an optical fiber link changes its polarization state by a polarization controller (PC) to be applied to a PBS. A first polarization component passes through a variable delay line, rotates by a predetermined angle, and is inputted to the PBS. A portion of a second polarization component is transmitted by a predetermined mirror. The reflected second polarization component is applied to the PBS to be combined with the first polarization component inputted to the PBS. The transmitted second polarization component passes through a photo-detector and a BPF. The filtered signal is inputted to a PC controller to select the smaller value among the currently and previously measured power values.

摘要： Disclosed herein is an Erbium-Doped Fiber Amplifier (EDFA) used in a WDM (Wavelength Division Multiplexing) transmission system. In accordance with the present invention, a variation of the intensity of the output optical signal in the optical fiber amplifier, which results from an gain imbalance due to different wavelength distribution caused by the gain inhomogeneity characteristics, can be prevented by examining the laser diode sensitive to the gain inhomogeneity characteristics in the erbium-doped optical fiber amplifier, constructing the filter having spectrum characteristics capable of suppressing the gain imbalance of the optical signal outputted from the optical fiber amplifier, and driving the sensitive laser diode using the electrical signal obtained by branching some of the input optical signal and passing the branched optical signal through the filter and driving other laser diodes with a constant voltage value.
