We propose and investigate a simply self-restored tree-type timedivision-multiplexed passive optical network (TDM-PON) with duplex fiber system against the fiber failure. The new proposed optical line terminal (OLT), optical network unit (ONU), and remote node (RN) can be used to prevent and protect the occurrence of fiber failure in the self-protected treetype PON. The protection and restoration time of the access network can be archived within 7 ms in this experiment. In addition, the
