Subject: Optical Communication Subject Code : EC1402 Year/Semester: IV year / VII sem AIM

Faculty Name: K. Sunilkumar Faculty Code: ECF-25

To introduce the various optical fiber modes, configurations and various signal degradation factors associated with optical fiber.

To study about various optical sources and optical detectors and their use in the optical communication system. Finally to discuss about digital transmission and its associated parameters on system performance
OBJECTIVE

To learn the basic elements of optical fiber transmission link, fiber modes configurations and structures. To understand the different kind of losses, signal distortion in optical wave guides and other signal degradation factors. Design optimization of SM fibers, RI profile and cut-off wave length. To learn the various optical source materials, LED structures, quantum efficiency, Laser diodes and different fiber amplifiers. To learn the fiber optical receivers such as PIN APD diodes, noise performance in photo detector, receiver operation and configuration. To learn fiber slicing and connectors, noise effects on system performance, operational principles WDM and solutions.
