Asymmetric ATM-PON interface compliant to ITU-T/FSAN standard for global optical access systems

Abstract: This paper presents a first optical access implementation prototype of asymmetric 622 Mbps/156 Mbps ATM-PON interface compliant to ITU-T/FSAN standard, with a dynamic bandwidth allocation mechanism for efficient IP traffic accommodation.

Circuit performance in a packet network: Demonstrating integrated Carrier Ethernet Switch Router (CESR) + Optical Transport Network (OTN)

Abstract: Circuit switched systems in the metropolitan and core networks are being steadily replaced by the packet optical integration brought about by the steady advances in Carrier Ethernet, Optical Transport Network (OTN) and Reconfigurable Optical Add-Drop Multiplexer (ROADM). We demonstrate a state-of-the-art Carrier Ethernet Switch Router (CESR) with integrated OTN function as a mechanism to better facilitate packet-optical integration leading to service and layer 2.5 routing support. The design, development of this CESR+OTN platform is described. The test-bed showcases an integrated high-speed optical network configured as an inter-connected ring topology of 16 nodes, multi-degree cross-connects and demonstrates next generation application services used for cloud computing and mobile backhaul. Performance results indicate that the packet optical technology proposed by us and showcased in a live test-bed compare similar to (or in some cases better than) a circuit switched network.

HDWDM upgrade of CATV fibre-coax networks for broadband interactive services

Abstract: To introduce broadband interactive services in a fibre-coax CATV network with high splitting ratio, a HDWDM upgrading strategy in combination with conventional TDMA (or SCMA) techniques is presented It features flexible network reconfiguration via wavelength reassignment at the optical network units Key system item is a novel cost-effective bi-directional erbium-doped fibre (/planar waveguide) amplifier handling simultaneously a high-grade analogue CATV downstream signal and multiwavelength interactive signals in a single fibre-coax network

What architectures make sense for fiber access networks

Abstract: A variety of access architectures have been examined. When DWDM is introduced, it is likely to first be used in the downstream direction only. For residential access, providing broadcast video, along with high-speed data, may provide the additional revenue necessary to justify deployment of optical systems. If so, integrating the broadcast video and data together into a single system seems to be the most cost-effective approach.

Dynamic Elastic and Scalable Photonic Infrastructures and Network Architectures

Abstract: In this article we discuss a new optical networking paradigm based on the co-called “Dynamic Elastic and Scalable Photonic Infrastructures and Network Architectures - DESPINA” approach. The concept, main elements and associated research directions are highlighted.
