METHOD FOR WAVELENGTH ADJUSTMENT OF WAVELENGTH MULTIPLEXED SIGNAL, AND OPTICAL TRANSMISSION SYSTEM

Title:

METHOD FOR WAVELENGTH ADJUSTMENT OF WAVELENGTH MULTIPLEXED SIGNAL, AND OPTICAL TRANSMISSION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2018/123650

Kind Code:

A1

Abstract:

This method for wavelength adjustment of a wavelength multiplexed signal involves: a step in which a control unit acquires information relating to multiple wavelengths from an optical transmitter that transmits a wavelength multiplexed signal obtained by multiplexing multiple wavelengths, and determines whether or not the multiple wavelengths satisfy a condition for producing four-wave mixing; and a step in which, if the multiple wavelengths are determined to satisfy the condition, the control unit adjusts at least one of the multiple wavelengths by controlling the optical transmitter.
