Latest Patents

Kiyo Ishii holds a patent for an optical switch and an optical node monitoring system and method. This invention aims to monitor signal flow in an optical node without the need for a monitor light. The system utilizes a portion of output signals that are turned back at each output port of the optical node. The output signal light undergoes intensity modulation or phase modulation, which is then assigned port identification information. This allows for the reversal of signals in the optical node. From the input port corresponding to the reversed output signal, multiple signals are output. These signals are converted appropriately and separated by a device with a spectroscopic function. Identification information is read based on the intensity of the signal light for each signal, enabling the determination of the optically switched state corresponding to the input port.
