Biconic taper wavelength division multiplexer(FBT),through the high temperature melting taper of two fiber,after packaged,to realize the separation of the two wavelengths or synthesis.
At present, the most commonly used wavelength of 1310nm and 1550nm two wavelength WDM.This fused WDM showed most of the 1x2 in the form of WDM.The package has a steel stube or ABS box packing.
