Next-Generation Optical Access Seamless Evolution: Concluding Results of the European FP7 Project OASE

Abstract

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

A Green Open Access Optical Distribution Network with Incremental Deployment Support

“…This encourages fair business competition. In such networks (see Table I), the PIP owns the ODN equipment and the NPs own only the equipment at the OLT [2], [3]. The ONUs are assumed to be owned by the users or in-home NPs.…”

“…This is termed as co-existence and prevents monopoly of NPs (SPs) with any particular technology. Co-existence of NPs with similar OLT schemes has been termed as concurrency in the literature [2]. [8]: The GOAID-ODN (see Fig.…”

“…r Each output port of the FS is associated with a feeder fiber and a RN 2,z input port. [2], [10]) ensures only one of the above types as they suffer from a trade-off between physicallayer security and flexibility of bandwidth sharing.…”

“…The cost analysis is done over this assumed business scenario and is targeted for the European market. Below, we compare the CapEx and OpEx of GOAID-ODN with the two flavors of open access architectures as proposed in [2] (open access with point of unbundling (PoU) at the remote node and OLT). We also quantify the utilization ratios in GOAID-ODN.…”

“…The OAN scheme proposed in [1] is good on sharing but poor on physical-layer security and passivity (passivity is a desirable feature). The passive optical network (PON) based OAN schemes proposed in [2], [3] have moderate physical-layer security that achieve limited sharing of the ODN between multiple BPs. Thus, there exists a trade-off between sharing the ODN and physical-layer security.…”
