To learn the basic elements of optical fiber transmission link, fiber modes configurations

To understand the different kind of losses, signal distortion in optical wave guides and other signal degradation factors

To develop the knowledge of optical signal sources and power launching.

To equip the students with basic skills required to understand and design such systems.

After completing this course the students should be able to:
1)Understand fiber optic concept to information transmission. Identify the elements of an optical fiber transmission link.
2)Understand optical fiber structure, wave guiding and fabrication.Calculate and simulate the attenuation and signal degradation due to intermodal and intramodal distortion.
3)Understand the structure, the performance and the signal analysis of optical sources. Understand the structure, the performance and signal analysis of optical detectors. Calculate power coupling losses due to connectors, splices, source output pattern and fiber numerical aperture.
4)Design optimum single mode and multimode fiber link.Design and analyze optical receivers.
