FSK3883 Fiber-Optic Communication 9.0 credits
Information for research students about course offerings
The course is given annually if there at least five undergraduate or graduate students have registered in the advance cours.
Content and learning outcomes
Course contents
Intended learning outcomes
Knowledge of fiber-optical components and systems with applications to communications. Parameters of devices that are relevant for the system performance are derived from physical descriptions, and form the input parameters for the design of fiber-optic links.
After a completed course, the participants should be able to:
- understand, describe, analyse, and compare the most important devices: optical transmitters, optical fibers, and optical detectors
- design digital fiber-optic links.
- simulate a multilevel coherent fiber-optic communication system using computer software
Literature and preparations
Specific prerequisites
Enrolled as PhD student.
It is anticipated that the students are acquainted with:
- Waveguides: Wave equation and the concept of modes.
- Solid-state electronics: p-n-junction
- Circuit theory: Impulse response, convolution, transfer function of linear systems.
- Signal theory: Auto correlation function, power spectral density

Examination and completion
If the course is discontinued, students may request to be examined during the following two academic years.
Grading scale
Examination
Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.
The examiner may apply another examination format when re-examining individual students.
TEN1: written exam, 6 hp, grading: P/F
Calculator, mathematic handbook, the course book and the lecture notes (but NOT exercise notes) are allowed and recommended aids
LAB1: laborations, 1.5 hp, grading: P/F
PRO1: projekt task, 1.5 hp, grading: P/F
Other requirements for final grade
To pass the course the student should pass the written exam, the lab exercises and the project assignment.
Opportunity to complete the requirements via supplementary examination
Opportunity to raise an approved grade via renewed examination
Examiner
Ethical approach
- All members of a group are responsible for the group's work.
- In any assessment, every student shall honestly disclose any help received and sources used.
- In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
