While both technologies share a similar physical topology, WDM-PON employs passive WDM MUX/DEMUX devices for wavelength management, creating a wavelength-based point-to-point logical connection that ensures user resource isolation. The ONU then converts the optical signals into electrical signals for the end-users to access. On the other hand, the uplink transmission involves. The passive optical network (PON) is an optical fiber based network architecture, which can provide much higher bandwidth in the access network compared to traditional copper-based networks. Incorporating wavelength-division multiplex-ing (WDM) in a PON allows one to support much higher bandwidth. Wavelength Division Multiplexing (WDM) is a technique used in fiber optic communication that allows multiple data signals to be transmitted simultaneously over a single optical fiber. It is a next-generation upgrade to traditional PON technologies that enhances.
