Wavelength Division Multiplexers (WDM) Suppliers in Shanghai, China

Wavelength division multiplexers (WDM) are devices that combine light signals with different wavelengths, coming from different fibers, onto a single fiber. They include dense wavelength division multiplexers (DWDM), devices that use optical (analog) multiplexing techniques to increase the carrying capacity of fiber networks beyond levels that can be accomplished via time division multiplexing (TDM).
