All-Optical Networks 2001
    

  

Morning Workshop:
Introduction to Optical Networking & Switching

Doug Green
Vice President
Ocular Networks

Greg Nulty
Vice President
Ocular Networks

Description:
This course is an introduction to optical networking. It brings the audience up to speed on the technologies and markets so they can better understand the market in general and get more out of specific presentations on specific technologies and products.

Topics covered include:

  • Optics 101 – an overview of technologies and concepts that make DWDM and optical networking work, including DWDM, OADMs, Optical Amplifiers, Cross Connects, and components.
  • History of Optical Networking – How DWDM transformed the long distance network, including a before-and-after analysis of the network: how routers found their way into the equation, how the OIF and ODSI were formed, etc.
    •
  • Optical Networking in the metro and access networks
  • Where optics are today and where optical technology is headed in the near future
