Home / Wavelength Division Multiplexing EDFA Principle
In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i. Dense Wavelength Division Multiplexing or DWDM is the method which allows multiple wavelengths to be brought to a single-mode fiber, consequently growing the potential of that particular transmission route by using a factor which is equal to the total number of wavelengths that one has added during. It can perform additional roles like providing redundancy, supporting advanced topologies, reducing hardware and cost, etc.
