Filter Wavelength Division Multiplexer FWDM Factory WDM Filter

A wavelength division multiplexer (WDM) couples multiple signals of different wavelengths to one
optical fiber for simultaneous transmission. It has a multiplexer and a demultiplexer. The main purpose
of WDM is to increase the available bandwidth of optical fiber, and it can be expanded through WDM
without laying more optical fibers. It is the main device for the expansion of modern optical fiber communication.
