Future 5G services are characterised by unprecedented need for high rate, ubiquitous
availability, ultralow latency, and high reliability. The fragmented network view that is …

Current trends in telecommunication networks foresee the adoption of the fifth generation
(5G) of wireless networks in the near future. However, a large number of people are living …

Scalability is a critical issue for access and aggregation networks as they must support the
growth in both the size of data capacity demands and the multiplicity of access points. The …

This paper reports on the architectural, protocol, physical layer, and integrated testbed
demonstrations carried out by the DISCUS FP7 consortium in the area of access–metro …

Optical code division multiple access (OCDMA) systems can support multiple classes of
service by differentiating code parameters, power level, and diversity order. In this paper, we …

Seeking reduction of capital and operational costs on next-generation fiber networks is the
holy grail of network planning and deployment for all operators worldwide. In particular …

While the concept of Software Defined Networking (SDN) has seen a rapid deployment
within the data center community, its adoption in telecommunications network has …

Long-reach passive optical networks (LR-PONs) prove to be a suitable candidate for future
broadband access networks. The longer reach of the feeder fiber in a LR-PON enables us to …

We propose and test a coherent all-optical orthogonal frequency-division multiplexing (AO-
OFDM) system, based on all-optical (de) multiplexing and coherent detection, for multiterabit …

The physical layout of cables and nodes in many of today's passive optical networks (s) still
dates back to the early days of copper loop installations, with customer to exchange node …
