The correct definition ofPOL (Passive Optical LAN)is that it is the application of PON (Passive Optical

Network) technology in the enterprise campus environment. POL leverages the advantages of fiber

optics, such as high bandwidth, long transmission distances, and low maintenance costs, to provide a

converged network solution for enterprises. It replaces traditional copper-based LANinfrastructure

with an all-optical network, supporting services like data, voice, and video over a single fiber.
