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)

Concepts



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

CPNSDM Ring

WDM Ring

Add/Drop Rings



The SDM RingThe SDM Ring

combines 12 space channels on a SM fibre ribbon

operates at 1300 nm

CPNSDM Ring

Add/Drop Rings



The WDM RingThe WDM Ring

combines 12 wavelengths on one SM fibre

operates around 1550 nm

with 1.6 nm channel spacing
