| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The method of switching the transmission line without interrupting service while temporarily dualing communication lines decreases the transmission quality due to causing the beat interference between carrier waves and the intersymbol interference between signals. We demonstrate with the calculation and the experiment that the wavelength conversion technology (XGM) is effective for the decrease of the beat interference. Then, the allowable optical path length difference without the intersymbol interference is estimated from the experiment. The error-free optical line switching technique with high reliability was able to be achieved by these solutions. | |
