Abstract:

To quantitatively and comprehensively evaluate the network reliability of the whole PON, a new passive optical network (PON) reliability model is proposed. It can indicate the failure's effect on the network or the different contributions of different nodes and links. Based on this model, the network reliability and cost of PONs in typical optical network unit (ONU) location situations with typical topologies are analyzed, the optimized location of splitter in one-splitter tree PON and trunk-protected tree PON is given.

Key words: passive optical network, network reliability, network cost, network design
