摘      要：Passive Optical Networks(PONs)are considered as the preferred solution for broadband fibre-based access *** is because PONs present low cost deployment,low energy consumption and also meet high bandwidth demands from end *** addition,end users expect a high availability for access networks,while operators are more concerned about reducing the failure impact(number of clients affected by failures).Moreover,operators are also interested in reducing the cost of the access *** paper provides a deep insight into the consequences that the physical topology and design decisions cause on the availability,the failure impact and the cost of a *** order to do that,the physical layout of the PON deployment area is approximated by a network geometric model.A PON deployed according to the geometric model is then assessed in terms of failure impact,availability and *** way,the effects of different design decisions and the physical layout on these three parameters are *** addition,the tradeoffs between availability,failure impact and cost caused by planning decisions and the physical topology are identified and pinpointed.
