in this paper, we proposed a number of innovative models for PON/ radio-over-fiber PON (RoF-PON) according to the ITU-T G.983.1 recommendations along with their m-trail design solutions. The RoF-PON system is based on our novel millimeter-waveband (mm-WB) RoF architecture for wireless services. We presented two architecture schemes for m-trail deployment: (1) by setting up the m-trails in addition/on the top of the operating lightpaths, this is the case which a clear separation between monitoring and operation functions is required, (2) by using a certain number of the existing light paths that are already deployed in the network at the normal operating condition as optical monitoring paths. The comparison between these two architecture schemes is based on network resources consumption in terms of the number of lightpaths that are needed to be deployed to achieve network survivability.

Passive Optical Networks (PON) support subscribers with bandwidth requirements more than 10 Mbps. Fiber and node failures in a PON network can lead to large amounts of data loss, while isolating the central office from the subscribers. Hence, high network availability is desired when a PON is used for business enterprises and for providing mobile backhaul services. To maximize network availability, several protection architectures have been proposed in literature. In this chapter, we critically analyze and compare novel WDM PON protection architectures amongst those proposed in the literature. The comparison is done from topology, resource utilization and power budget perspectives. We also discuss protection mechanisms that are typically used in the architectures and their impact on restoration.
