Frequency-Shift Monitoring of Optical Filter Based on Optical Labels over FTN-WDM Transmission Systems
Optical network monitoring and soft failure identification such as optical filter shifting and filter tightening are increasingly significant for the complex and dynamic optical networks of the future. Center frequency shift of optical filtering devices in optical networks has a serious impact on th...
