Comparative study of the m-trail possible solutions for wireless/ optical access networks

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.
