Abstract
An optical wavelength controlling method and a system thereof for an optical wavelength division multiplexing transmission system, wherein a plurality of wavelengths of channels are multiplexed and transmitted by an optical transmitting unit, and the multiplexed wavelengths are divided into the wavelengths of the channels by an optical receiving unit, are disclosed.The optical wavelength controlling method includes:a step of reducing optical power of the wavelength of a target channel, and transmitting the wavelengths;a step of evaluating channel crosstalk based on a code error rate of a channel adjacent to the target channel, and detecting a shift of the wavelength of the target channel; anda step of compensating for the shift of the wavelength of the target channel.
