PON uses wavelength division multiplexing
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. A Wavelength Division Multiplexing Passive Optical Network (WDM-PON) is an advanced optical access network architecture that uses wavelength division multiplexing (WDM) to deliver high-bandwidth services to end-users. Incorporating wavelength-division multiplex-ing (WDM) in a PON allows one to support much higher bandwidth. A bidirectional WDM-PON system based on a Fabry-Perot laser diode (FP-LD) with two cascaded array waveguide gratings (AWGs) has been demnstrated. The downstream data rate equals to 10 Gbps and the upstream data rate equals to 2.
