1 Concepts Add/DropRings Trial Network Nodes Components Management Applications Consortium COBNET contact: Jacques Saint-Blancat Corporate Optical Backbone Networks l COBNET's goal is to establish concepts and technologies for the next generation of Corporate Backbone Networks Objectives and Concepts l COBNET is applying evolving optical multichannel technologies l COBNET is pursueing the concept of Add/Drop Rings l wavelength division multiplexing (WDM) l optical space division multiplexing (SDM) Concepts

2 Concepts Add/DropRings Trial Network Nodes Components Management Applications Consortium COBNET contact: Jacques Saint-Blancat The Customer Premises Network Backbone l builds on Optical SDM Add/Drop Rings for short CPN distances or inside buildings l and on WDM Add/Drop Rings for larger CPN distances or for private MANs Add/Drop Rings

3 Concepts Add/DropRings Trial Network Nodes Components Management Applications Consortium COBNET contact: Jacques Saint-Blancat The SDM Ring l combines 12 space channels on a SM fibre ribbon l operates at 1300 nm Add/Drop Rings

4 Concepts Add/DropRings Trial Network Nodes Components Management Applications Consortium COBNET contact: Jacques Saint-Blancat The WDM Ring l combines 12 wavelengths on one SM fibre l operates around 1550 nm l with 1.6 nm channel spacing Add/Drop Rings

5 Concepts Add/DropRings Trial Network Nodes Components Management Applications Consortium COBNET contact: Jacques Saint-Blancat The Trial Network Norwich Ipswich London Cambridge GEC Marconi Labs BT Labs l CPN backbones are established at two partner sites. l A field trial in East England verifies concepts and technologies. Trial Network

6 Concepts Add/DropRings Trial Network Nodes Components Management Applications Consortium COBNET contact: Jacques Saint-Blancat The Trial Network Norwich Ipswich London Cambridge GEC Marconi Labs BT Labs l Wide-area CPN interconnection is provided across fibres of BT's London East Anglian Network LEANet Trial Network

7 Concepts Add/DropRings Trial Network Nodes Components Management Applications Consortium COBNET contact: Jacques Saint-Blancat The Trial Network Norwich Ipswich London Cambridge GEC Marconi Labs BT Labs l allowing clear-channel WDM connectivity across 180 km Trial Network

8 Concepts Add/DropRings Trial Network Nodes Components Management Applications Consortium COBNET contact: Jacques Saint-Blancat The Trial Network Norwich Ipswich London Cambridge GEC Marconi Labs BT Labs A closer look at the nodes Trial Network

9 Concepts Add/DropRings Trial Network Nodes Components Management Applications Consortium COBNET contact: Jacques Saint-Blancat The Trial Nodes l Wavelength or space channels are added/dropped in simple, low-cost Optical Add/Drop Nodes l all other channels are bypassed optically Nodes

10 Concepts Add/DropRings Trial Network Nodes Components Management Applications Consortium COBNET contact: Jacques Saint-Blancat The Trial Nodes l Wavelength and/or space channels are interchanged in a hybrid WDM/SDM Cross-Connect Node Nodes

11 Concepts Add/DropRings Trial Network Nodes Components Management Applications Consortium COBNET contact: Jacques Saint-Blancat The Trial Nodes l Alternatively, channels may be switched to the WDM WAN via a Public Network Interface Unit Nodes

12 Concepts Add/DropRings Trial Network Nodes Components Management Applications Consortium COBNET contact: Jacques Saint-Blancat Economy is supported by the development of specific technological components... The Components l WDM Lasers Components

13 Concepts Add/DropRings Trial Network Nodes Components Management Applications Consortium COBNET contact: Jacques Saint-Blancat The Components l SDM Laser Arrays Components
