Things You Should Know About WDM Filter
The optical devices most often used to selectively transmit certain wavelengths are called filter, which covers a broad range of devices, including attenuators. Filters play important roles in Wavelength Division Multiplexing(WDM) systems, although other technologies also may be used. WDM … Continue reading

Filter-based Wavelength Division Multiplexer
Filter-based Wavelength Division Multiplexer (Filter WDM, or FWDM) is based on the mature membrane filter technology, with a wide channel bandwidth, low insertion loss, high channel isolation degrees and high environmental stability and reliability. It is widely used in single-mode … Continue reading
