Process for detecting detuning in wavelength splitters in a fiber optic transmission network and a fiber optic transmission network

摘要

The process of detecting the existing detuning in a wavelength splitter in a fiber optic transmission network evaluates predicted values associated with at least two optical subcarriers and determines actual values associated with the at least two optical subcarriers. And. A wavelength shift value that quantifies the existing detuning is obtained from the comparison of the predicted value and the measured value. The process can be completed by updating the tuning of the light source from which the subcarriers are derived to reduce wavelength shift.
