FWDM (Filter Wavelength Division Multiplexing) filter is based on mature film filter technology. Filter-type wavelength division multiplexer can blend or separate different wavelengths of light in a wide range of wavelengths, and is widely used in erbium-doped optical amplifiers, Raman amplifiers and WDM fiber networks. The 3-port filter type WDM introduced by GLSUN selects the film filter with excellent performance to ensure the high quality optical performance and is stable and reliable. The filter type WDM can double the transmission capacity of a single fiber and realize the bidirectional fiber communication, which is widely used in fiber upgrading, expansion or introduction of comprehensive new services. #fwdmopticaldevice#fwdmdevice#fwdmfilter#fwdmfiberdevice,#fwdmsolution
