摘要： An optical amplifier for wavelength multiplex transmission is capable of reducing the gain difference of each wavelength. A pumping light source generates pumping lights to excite an optical fiber for amplification for amplifying wavelength multiplexed optical signals, a wavelength optical multiplexer inserts these pumping lights to the optical fiber for amplification, an optical coupler branches the optical signals amplified by the optical fiber for amplification, and a wavelength separator separates the branched optical signals into ASE and signal lights. A photo receiver detects the strength of separated ASE, a photo detector detects the strength of signal light. A strength level comparator/pumping light source controller controls the output of the pumping light source, based on the strength detected by the photo detector so that the output level of the optical signal is set arbitrary. Therefore, by controlling the output level of the pumping light source, it is capable of setting the amplification factor of suitable gain flatness.

摘要： A light amplifier is provided which is capable of maintaining the output light of excitation light sources at a constant level even when the light power input into the rare earth containing optical fiber fluctuates due to the tracking error of the excitation light source or due to the temperature characteristic or the polarization dependence of the excitation light multiplexer. The light passed through the rare earth containing optical fiber is extracted after being split by the splitting device 3, and output levels of the excitation light sources and are controlled by a control circuit in response to the levels of the extracted light. Consequently, the light output can be maintained at a constant level even when the excitation light power input into the optical fiber fluctuates due to the polarization dependence or the temperature characteristic of the light multiplexer for supplying the excitation light into the optical fiber.

摘要： A compensation scheme for an optical amplifier that reduces differences in gain observed at various wavelengths combines and controls characteristics of an automatic gain control circuit and variable gain equalizers. The peak gain wavelength typically observed in optical amplifiers is reduced by shifting the variable gain equalizer characteristic, which has a wavelength region of maximum gain loss. By combining the characteristics of the peak wavelength gain with the maximum wavelength loss according to the various elements, a smooth gain curve can be realized. A variable gain equalizer control circuit provides the required control, and can control multiple variable gain equalizers positioned in various numbers and locations with regard to an optical amplifier section.

摘要： Optical surge preventing systems and methods for rare earth-doped optical fiber amplifiers are disclosed. The systems are so arranged as to cause any signal existing in a doped fiber section so as not to over excite the rare earth elements in the doped fiber section. In one embodiment, a background signal light with such a wavelength as to cause induced emission in the doped fiber section is always coupled into the doped fiber section regardless of whether a message signal light exists or not. The background signal light may be generated by any suitable light source or a light spontaneously emitted from either end of the doped fiber section. In another embodiment, a dummy signal light is coupled into the doped fiber section if the level of the message signal light becomes less than a predetermined value. Coupling of the background signal light or the dummy signal light into the doped fiber section may be done from either of the message signal input and output sides.
