The simulation models for a typical PON layout are developed and three major PON technologies are considered. The models support the analysis of various important characteristic parameters, namely: 1) link budget for acceptable losses from splices, attenuation and splitters, 2) link performance characterization based on data (BER, SNR) or video signal(More)
In this paper, desirable performance of fault localization process in all-optical networks is presented by employing the recently introduced Monitoring-Trail (m-trail) (that was proved to yield better performance by establishing monitoring resources in a shape of trails). As well, a new technique for deploying m-trails on networks along with its established(More)
In this paper, desirable performance of fault localization process in all-optical networks is presented by employing the recently introduced Monitoring-Trail (m-trail) (that was proved to yield better performance by establishing monitoring resources in a shape of trails) [1].

Routing and wavelength assignment (RWA) is an important and difficult topic in wavelength division multiplexing (WDM) networks if the node blocking probability is taken into consideration. Here we introduce a new method aimed at minimizing this problem by finding the most suitable route for a coming connection request based on blocking probability(More)
In this paper, desirable features of network architectures and enabling novel technologies for delivering future millimeter-waveband (mm-WB) radio-over-fiber (RoF) system for wireless services with the use of dense wavelength division multiplexing (DWDM) architecture is proposed. For the conceptual illustration, we considered a DWDM RoF system with channel(More)
In this paper, we will propose some models for PON/RoF-PON combines a number of ideas used before in the research papers, the ITU-U recommendations and also a number of novel models. We compare between those proposed models by using the Expected Survivability Function; a simple and intelligent tool to evaluate network survivability. The analysis was done(More)
In this paper, desirable performance of fault localization process in all-optical networks, by employing the recently introduced Monitoring-Trail (m-trail), is explored and a focus is given to the analysis on using m-trails with established lightpaths. A novel technique based on Geographic Midpoint Technique, an adapted version of the Chinese Postman's(More)
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:(More)
In this paper, an enhancement to the novel Geographic Midpoint (GMP) routing algorithm is introduced. The proposed enhancement improves the original algorithm to be more efficient in providing the targeted route. This is done by producing a new midpoint for every iteration of the algorithm that adds more accuracy to the process. A number of direct(More)
In this article, an enhancement to the novel Geographic Midpoint (GMP) routing algorithm is introduced. The proposed enhancement improves the original algorithm to be more efficient in providing the targeted route by considering distance variations of links to be connected. A number of direct applications like the solution of the Monitoring-Trail (m-trail)(More)
