Total cost reduction achieved by offering protection in PON architectures
Offering protection in access networks has been thought to be significantly expensive. This paper proposes a new way to provide protection in TDM and WDM PONs. It is shown that very low extra investment is needed to provide protection in the case when it is foreseen during network planning. It is also studied how the total cost is reduced due to the significant diminution of the OPEX related to the failure management.
