Transparent Ring Interconnection Using Multiwavelngth PHotonic switches

Project description


Broadband for all
Transparent Ring Interconnection Using Multi-wavelength Photonic switches

Main Objectives:

This project proposes the development of network architectures and system solutions that will facilitate future broadband access networks. The effort will focus on Transparent Ring Interconnection using multi-wavelength photonic switches with the aim to increase the network functionality and capacity. The proposed scenario refers to a high capacity networks with transparent connectivity between core/regional-metro rings supporting data rates up to 160Gbit/s and metro-access rings supporting up to 40Gbit/s. The required functionality in such architecture will be provided through an optical switching node located at the interconnection points between rings. The design and development of this node will be the focus of the project with the aim to provide a cost effective solution that can transparently offer inter-domain connectivity. This solution will also support functionalities currently unavailable in the optical layer. Our approach will offer transparent optical grooming/aggregation and multi-wavelength 2R optical regeneration. This transparency will enable a variety of data rates, protocols and formats that are present in the metro and access network environments and are associated with the requirements of new and emerging services and applications that are rapidly becoming available to the end-users.
Technical Approach :

The work described above is planned to be performed within the framework of 6 different workpackages that are closely linked. One additional workpackage was dedicated to project management.
* WP2: One of the main objectives of this workpackage is to define the network architecture that the project will focus on. It will also provide the network and system level requirements and specifications. Comparative studies among various technology options together with value analysis studies and benchmarking will be also performed.
* WP3: The main activity of this workpackage is the development of a fully functional optical switching node for CWDM operation that includes the design, the implementation and the performance evaluation of the optical switching node at data rates between 10 Gbit/s and 160 Gbit/s.
* WP4: This workpackage focuses on the design, fabrication and characterization of devices suitable for 2R multi-wavelength regeneration. The technologies that will be used are active involving quantum-dot semiconductor optical amplifiers and passive involving highly nonlinear fibers.
* WP5: This workpackage will focus on the development of linear and nonlinear optical modules
* suitable to perform transparent grooming and aggregation involving also bit-rate adaptation. These modules will offer mapping of WDM channels to OTDM signals and vice versa.
* WP6: This workpackage will concentrate on the demonstration of the developed sub-systems in a network environment based on a lab testbed, consisting of optical nodes and emulated transmission impairments as well as in a demo together with a commercially available system.
* WP7: This work package will focus on drawing a manufacturability plan for the commercialization of the TRIUMPH platform. It will generate intellectual property and disseminate the project results.

This consortium proposes the development of network architectures and systemsolutions suitable for future broadband networks. The main objective is to provideTransparent Ring Interconnection Using Multi-wavelength PHotonic switches andprocessing to significantly increase the network functionality and capacity. Theproposed scenario refers to a high capacity network with transparent connectivitybetween core/regional-metro rings supporting up to 160Gb/s and metro-access ringssupporting up to 40Gbit/s. The required functionality in such architecture will beprovided through an optical switching node located at the interconnection pointsbetween rings. The design and development of this node will be the focus of theproject with the aim to provide a cost effective solution that can transparentlyoffer interdomain connectivity. This solution apart from transparent opticalswitching will support functionalities currently unavailable in the optical layer.Our breakthrough approach will offer transparent optical grooming/aggregation andmulti-wavelength optical regeneration. This transparency enables a variety of rates,protocols and formats that are present in the metro and access network environmentsand are associated with the requirements of new and emerging services andapplications that are rapidly becoming available to the end users. This will beperformed using novel passive and active optical technologies offering reduced costable to replace existing complicated and expensive equipment. These technologieswill be developed and deployed in the system context by the project consortium thathas a unique combination and complementarity of the required technical expertise andknow how. The functionality and performance of the optical switching node will bedemonstrated through a network lab trial in which it will be used to interconnecttwo collector and one core-metro rings.
