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. While it follows the FTTx point-to-multipoint topology, there are marked differences between the two technologies: TDM-PON WDM-PON TDM-PON WDM-PON While both technologies. The ONU then converts the optical signals into electrical signals for the end-users to access. 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. 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.
Using WDM in PONs allows for more efficient use of fiber, supports higher data rates, and enables the delivery of multiple services over a single network. It also provides a path for network evolution,
