What is the primary role of WDM in optical networks?

Explanation:
Wavelength Division Multiplexing increases the capacity of an optical link by sending multiple data streams through the same fiber, each on its own distinct wavelength of light. By multiplexing several wavelengths, a single fiber can carry many channels simultaneously, dramatically boosting total bandwidth without laying new fiber. This is different from timing and synchronization (which deals with clocks across devices), encryption (security of the data), or the basic electrical-to-optical conversion done by transmitters—WDM simply combines and later separates the different wavelengths so multiple signals can share the same fiber.
