Catalog Description:

Physical layer issues for component and system technologies in optical fiber networks. Sources of physical layer impairments and limitations in network scalability. Enabling technologies for wavelength-division-multiplexing and time-division-multiplexing networks. Optical amplifiers and their impact in optical networks (signal-to-noise ratio, gain-equalization, and cascadability). Note: Students previously enrolled in course EEC239 may not receive credit for this course.

Course Overlap:
This course sequence (EEC239 A,B) covers physical layer and interfaces with architecture and protocol discussed in ECS 259 (Optical Networks) in the Computer Science Department. More rigorous and detailed analysis of optical components are being offered through EEC 235 (Photonics) and EEC 238 (Semiconductor Diode Lasers).
