Title:
WAVELENGTH CONVERSION DEVICE, TRANSMISSION DEVICE, AND TRANSMISSION SYSTEM
Document Type and Number:
Japanese Patent JP2022128895
Kind Code:
A
Abstract:
To provide a wavelength conversion device or the like that increases the number of signal wavelengths while corresponding to subsequent part characteristics after wavelength conversion even when there are dispersions in the zero dispersion wavelength of a wavelength conversion medium.SOLUTION: A wavelength conversion device includes a first wavelength conversion part and a first generation part. The first wavelength conversion part wavelength-converts, by passing first multiplex light obtained by multiplexing an optical signal of a first wavelength band from each transmitter through an inside of a wavelength conversion medium by using excitation light, the first multiplex light into second multiplex light in a second wavelength band. The first generation part generates a first control signal that controls each transmitter to shift a signal wavelength of each optical signal in the first multiplex light before wavelength conversion according to a subsequent component to which the second multiplex light after wavelength conversion in the first wavelength conversion part is input, and transmits the first control signal to each transmitter.SELECTED DRAWING: Figure 2
