NUST School of Electrical Engineering and Computer Science A center of excellence for quality education and research CSE430 FIBER OPTIC COMMUNICATION SYSTEMS Prerequisite: Instructor: Office: Class Hours Class Timings: Class room: Fall 2008 Credit-Hours: 3+ 0 Syed Ali Haider Faculty Block 2:20pm – 3:10pm Tue 10:00am – 11:50am Thu CR#14, UG Block Email: ali.haider@niit.edu.pk Consulting Hours Monday: 3pm to 4pm Any Other Time: By Appointment via Tel / Email Course Objective: This course is intended to give an overview of fiber, fiber communication and components used in optical communication. Important problems will be discussed to understand the in-depth functionality of optical networks. In this course students will study about optical theory, optical communication system(s), optic fiber waveguide, light sources, light detectors, couplers and connectors, modulation and optical networks.

The question framed is to test the concepts involved in last lecture. It will be the instructor’s will to choose the number of quizzes for evaluations purposes normally 3 in number. Assignments In order to judge that student understands the course, practice and comprehensive home assignments will be given. The students are advised to do the assignments individually. Copying of assignment is highly discouraged and taken as cheating case and will be forwarded for disciplinary action. The questions in assignment are more challenging to give students the confidence and extensive knowledge about the subject and enable them to prepare for the exams. Don’t forget to place Assignment Front Page on top of all hard-copy submitted assignments.
