Survivable and Reliable WDM-PON System With Self-Protected Mechanism Against Fiber Fault

In the paper, we present and design a self-restored wavelength multiplexing division passive optical network (WDM-PON) configuration to prevent the fiber failure and data disconnection. Here, the new remote node (RN) and optical network unit (ONU) are proposed in the fiber network to provide the protection behavior to increase the network reliability and flexibility. Moreover, the network performances of WDM signals are also analyzed and discussed.
