An introduction to components, systems, and the enabling technology underlying the optical networking. The enabling technology includes single-wavelength and Wavelength Division Multiplexing (WDM) systems. Optical layer architecture and design are the primary focus of the course, which includes current infrastructure architecture, the operation, deployment, administration and maintenance of networks, the fault and alarm handling, the protection strategies, the access schemes and interfacing with wireless/copper network systems. The course also introduces latest advances like the free-space optical networking and the optical burst networking. Graduate status in the School of Technology or graduate status in another school, with appropriate objectives and preparation. Permission of instructor required.
