Wavelength Division Multiplexing (WDM)
Wavelength Division Multiplexing (WDM) is a technology used in fiber optics to transmit multiple signals simultaneously over a single optical fiber. It achieves this by using different wavelengths, or colors, of light for each signal, much like how a prism separates light into a spectrum. By combining these wavelengths at the transmitter and then separating them at the receiver, WDM increases the capacity of the fiber, allowing for more data to be transmitted at once, which is essential for high-speed internet and telecommunications. This makes communication faster and more efficient.

Wavelength Division Multiplexing (WDM) is a technology that allows multiple signals to be transmitted simultaneously over a single optical fiber by using different light wavelengths (or colors). Think of it like a multi-lane highway where each lane carries its own type of traffic. By using WDM, telecommunication companies can increase the capacity of fiber optic networks, enabling faster internet and more data transmission without needing additional cables. This efficient use of existing infrastructure is vital for handling the growing demand for bandwidth in our increasingly connected world.
