A wavelength-tunable add-drop-multiplexer based on fiber Bragggrating is demonstrated.The linear tuning range of this fiber grating is 5.3nm to select different channels.The capability of the device is measured with the broadband light source.The demultiplexing experiment has been successfully completed in the fiber transmission experimental system using a 4-wavelength all fiber laser as the signal source.The experimental results show that it can drop optical signal very well and the interchannel isolation is up to 29dB.It can be used in practical WDM system.
