D.
Allocate different signals to different time slots
Answers
D.
Allocate different signals to different time slots
Suggested answer: A

Explanation:

WDM (Wavelength Division Multiplexing) allows transmission systems to transport multiple signals transparently, onto several wavelengths, all together over one single fiber. This allows for increased capacity, as many different signals can be transmitted at the same time and along the same fiber.

Other advantages include improved signal integrity and reduced signal attenuation.
