## Context and introductory items

- The following charts reflect Nortel’s leadership in advanced optical networking and continuing commitment to development of advanced optical networking technologies
- This roadmap is not based on a specific “testbed” but rather on Nortel’s portfolio of optical products/features and that part of Nortel’s $2B annual research budget pertaining to optical
- Currently available or committed to development
- In pre-development phase or the basis of research activity
-  Key to next three charts:

**Technology & services currently available or committed to development**

**Technology & services in pre-development phase and/or under research**
