“…Footprint per line is defined as the floor space of all the network equipment that is taken on a per user basis. The methodology for the footprint calculation can be found in [16]. For all the variants of WDM-PON architectures, node consolidation does not make an obvious impact on the total footprint per line.…”

Abstract-Increasing bandwidth demand drives the need for next-generation optical access (NGOA) networks that can meet future end-user service requirements. This paper gives an overview of NGOA solutions, the enabling optical access network technologies, architecture principles, and related economics and business models. NGOA requirements (including peak and sustainable data rate, reach, cost, node consolidation, and open access) are proposed, and the different solutions are compared against such requirements in different scenarios (in terms of population density and system migration). Unsurprisingly, it is found that different solutions are best suited for different scenarios. The conclusions drawn from such findings allow us to formulate recommendations in terms of technology, strategy, and policy. The paper is based on the main results of the European FP7 OASE Integrated Project that ran between

“…Then, dependability-related OPEX can be reduced. Several reliable architectures have been proposed in literature [3][4][5][6][7][8][9][10][11][12]15,19,20]. Most of these architectures focus on protecting the fiber infrastructure, as it is one of the most failure-prone elements in PONs.…”

“…In fact, several neighborhoods and cities follow a regular grid, like the neighborhood of L' Eixample in Barcelona, Sacramento, Portland or Houston. Hence, this model has been widely used in several PON studies [9,17,20]. Considering CAPEX, the model allows for easy calculation of PONs' infrastructural needs.…”

“…Thus, increasing the dependability of PONs in a cost-efficient manner has been a case of concern over the last years. Actually, several protection schemes and dependability-cost analyses for different PON and NG-PON flavors can be found in literature [3][4][5][6][7][8][9][10][11][12]. Typically, the dependability of a system is assessed by parameters such as its availability or reliability.…”

“…On the physical layer of a hybrid PON, both TDM and WDM transmission (downstream and upstream) channels are utilized in the same PON. A hybrid PON facilitates better bandwidth usage by adding a TDM layer on top of the WDM layer [3], therefore it is flexible enough to deploy TDM/WDM technology depending on the type (i.e., unicast/multicast) and amount of traffic demand of the end-users. The advantages of a hybrid PON are twofold: (i) it can offer increased data rate to each user by employing WDM technology, (ii) it can provide flexible bandwidth utilization by employing TDM technology.…”

We investigate FTTX (Fiber-to-the Home/Premises/Curb) Passive Optical Networks (PON) for the deployment of broadband access networks such that the opportunities of optical fiber enabled technologies as well as of passive switching equipment can be exploited. We focus on designing the best possible architectures of hybrid FTTX PONs, which embraces both TDM and WDM technology. Advantages of hybrid PONs are twofold: they can (i) offer increased data rate to each user by employing WDM technology, (ii) provide flexible bandwidth utilization by employing TDM technology.We propose a novel network design optimization scheme for greenfield deployment of a set of hybrid PONs. For a given geographical location of an optical line terminal (OLT), a set of optical network units (ONUs) and their corresponding aggregated traffic demand, our proposed optimization scheme determines the design and dimensioning of the most economical set of hybrid PON networks while satisfying unicast/multicast traffic demands and taking into account the signal attenuation constraints. Computational experiments have been conducted on a set of up to 512 ONUs in order to evaluate the performance of the proposed scheme.
