CCorporate orporate OOptical ptical BBackbone ackbone NetNetworksworks
COBNET's goal is to establish concepts and technologies for the next generation of Corporate Backbone Networks
Objectives and Concepts
COBNET is applying evolvingoptical multichannel technologies
COBNET is pursueing the concept ofAdd/Drop Rings
wavelength division multiplexing (WDM)
optical space division multiplexing (SDM)

The Customer Premises NetworkThe Customer Premises Network Backbone Backbone
builds on Optical SDM Add/Drop Rings for short CPN distances or inside buildings
and on WDM Add/Drop Rings for larger CPN distances or for private MANs
