Understanding Wavelength Division Multiplexing (WDM)

What is WDM?

Wavelength Division Multiplexing (WDM) is an optical technology used to increase bandwidth over existing fiber optic networks.
The technology works by combining multiple wavelengths or channels of light into a single strand of fiber, where each channel transmits data independently at its own unique wavelength.
This enables the simultaneous transmission of multiple data streams over the same physical medium.

How Does WDM Work?

In essence, WDM works by assigning each data channel a different wavelength (color) of laser light.
These wavelengths are then combined and transmitted together over a single optical fiber.
At the receiving end, the wavelengths are separated back into individual channels for data processing.
This method significantly enhances the data-carrying capacity of optical fibers, greatly improving transmission efficiency.
