Dense Wavelength Division Multiplexing (DWDM)

Dense Wavelength Division Multiplexing (DWDM) is a technology that allows multiple data signals to travel simultaneously over a single optical fiber by using different wavelengths (or colors) of light. Think of it like a multi-lane highway where each lane carries a separate stream of traffic, allowing for higher data capacity and more efficient use of the fiber. DWDM enables high-speed internet, cable TV, and telecommunications to operate more effectively, accommodating the growing demand for bandwidth while minimizing infrastructure costs.
