SC261 - ROADM Technologies and Network Applications
Monday, 21 March
13:30 - 16:30
Short Course Level: Advanced Beginner
Thomas Strasser; Nistica Inc., USA
Short Course Description:
In the past few years optical transmission platforms around the world have aggressively adopted Reconfigurable Optical Add-Drop Multiplexer (ROADM) technology. This technology is now firmly integrated into the product lines and roadmaps of transport systems and carriers with deployment of more than $1 billion of ROADM transport in the last year. This represents a groundbreaking commercial technology transformation of transparent optical routing displacing electrical grooming equipment for the first time on such a wide scale. Despite the commercial success, substantial confusion has surrounded this technology. This is largely because (a) the ROADM market is poorly defined since it may mean a subsystem or a system, neither of which have market-accepted minimum functionalities; (b) the lack of a clear market definition has been exploited to promote competing technologies driven by different commercial interests; and (c) there continues to be technology innovation that improves flexibility of these systems. This course will give a historical perspective of how this technology evolved, the numerous network benefits derived, and how those benefits depend on the functionality of the technology employed. Finally, the course will describe how these technologies are being integrated into WDM systems and what types of networks most fully leverage the new capabilities to provide network value.
Short Course Benefits:
This course should enable you to:
Describe the network level benefits of ROADM systems.
Define the different ROADM technology approaches competing in the market.
Summarize the functionality differences between competing ROADM technologies, including which are most likely to succeed in the long term and why.
Compare the incremental cost of a ROADM to the network level savings it enables.
Discuss the types of networks that most fully benefit from ROADM technology and why.
Explain the contradictory statements made about ROADM in trade literature.
Short Course Audience:
Anyone interested in more fully understanding the functionalities and benefits of ROADMs, including students, researchers, engineers, managers, and executives involved in ROADM development, network design, network planning, and network operations
Thomas A. Strasser received a doctorate from Cornell University designing periodic guided-wave devices and worked for three years at Eastman Kodak Research Labs and seven years at Bell Labs in Murray Hill, New Jersey. At Bell Labs his group invented and developed manufacturing for enabling technologies in the next-generation transmission platforms of AT&T and Lucent Technologies. He served for five years as the chief
