Course Objectives:
Following the completion of this course, students will obtain the knowledge needed to perform fiberoptic communication system engineering calculations, identify system tradeoffs, and apply this
knowledge to modern fiber optic systems. This will enable the students to evaluate real systems and
understand the most recent literature in the field of fiber-optic communications.
Course Description:
Overview of optical fiber communications, optical fibers: Geometrical-optics description, wave
propagation, dispersion in single-mode fibers, dispersion induced limitations, fiber losses, nonlinear
optical effects, fiber manufacturing; Optical transmitters: basic concepts, light-emitting diodes,
semiconductor lasers, control of longitudinal modes, laser characteristics, transmitter design; optical
receivers: basic concepts, common photodetectors, receiver design, receiver noise, receiver sensitivity,
sensitivity degradation, receiver performance; Lightwave systems: system architecture, power budget
and rise-time budget, long-haul systems, sources of power penalty, computer-aided design; optical
amplifiers: Basic concepts, SOA, Raman amplifiers, EDFA, system applications; Dispersion management;
multichannel systems: WDM lightwave systems, WDM components, system performance issues, TDM,
code-division multiplexing; soliton and coherent lightwave systems, COOFDM; optical networks.
Course Policy:
1. It is the student’s responsibility to gather information about the assignments and covered topics
during the lectures missed. Regular class attendance is mandatory. Points will be taken off for
missing classes. Without 70% of attendance, sitting for final exam is NOT allowed. According to
IUB system students must enter the classroom within the first 20 minutes to get the attendance
submitted.
2. The date and syllabus of quiz, midterm and final exam is already given here, however,
announcements will be given ahead of time. There is NO provision for make-up Class Tests.
3. The reading materials for each class will be given prior to that class so that student may have a
cursory look into the materials.
4. Students should take tutorials with the instructor during the office hours. Prior appointment is
required.
5. Students must maintain the IUB code of conduct and ethical guidelines offered by the school of
engineering and computer science.

Assessment and Marks Distribution:
Students will be assessed on the basis of their overall performance in all the exams, quizzes, and class
participation. Final numeric reward will be the compilation of (tentative):
 Class tests (20%)
 Assignment (15%)
 One mid-term test (25%)
 Final exam (25%)
 Course project (15%)
Grade Conversion Scheme:
The following chart will be followed for grading. This has been customized from the guideline

Required Text:
The course will be based mostly on the following books:
1. Govind P. Agrawal, "Fiber-Optic Communication Systems," John Wiley & Sons, Inc.
2. Gerd Keiser, "Optical Fiber Communications," McGraw-Hill.
3. Rajiv Ramaswami, et. al., “Optical Networks”, Morgan Kaufmann.
Audit:
Students who are willing to audit the course are welcome during the first two classes and are advised to
contact the instructor after that.
Note:
Plagiarism – that is, the presentation of another person’s thoughts or words as though they were the
student’s own – must be strictly avoided. Cheating and plagiarism on exam and assignments are
unacceptable.
University Regulation and Code of Conduct:
Please see the Green Book for further information about academic regulation and policies, including
withdrawal and grading, appeals and penalties for plagiarism and academic misconduct.
Students with Disabilities:
Students with disabilities are required to inform the Department of EEE of any specific requirement for
classes or examination as soon as possible.
