EE8114
- Optical Communication Systems and Networks
The objective of the course is to provide a comprehensive understanding of optical communication
systems and basic networks. The course covers both guided wave propagation along single/multimode optical fibers and unguided propagation resulting in optical wireless communications, including Visible Light Communications (VLC). Various challenges of VLC and Fiber Optic Networks for IOT systems will be discussed. We start with basics of light waves and their propagation. We then cover optical sources and their modulation techniques; optical receivers and the optimization of SNR under different operating conditions. Then we will study basic design calculations for point-to-point fiber optic links and, star, bus and ring topology networks. Wavelength Division Multiplexed (WDM) networks, Synchronous Optical Networks (SONET) and Passive Optical Networks (PON) will also be studied. Then we will look into the design aspects of radio over fiber (ROF) networks.

3.4 Other
Expectations and Requirements
The term paper shall confirm the format given
at http://www.ee.ryerson.ca/~courses/ee8114/formatting.html
Plagiarism: Reproducing other's work or idea
without proper citation is defined as plagiarism. If your work found to have
plagiarized material, you will get zero marks for the work. If the offence is
serious, then it may be reported to the academic council as an academic
misconduct.
Note: Significant portion of research is
studying what others have done. Then an attempt is made enhance the work by
adding more. Therefore, a well-written paper should clearly mention relevant
previous work and clarify what is done new.
4. Variations within a Course
There will be no variations. All the students will follow the same guidelines.
5. University and School of Graduate
Studies Academic Policies
For information on academic
policies pertaining to issues such as course management, grading practices, and
appeals, students are to refer to the Ryerson Senate Policies: Policy 142 – Graduate Admission
and Studies, Policy 151 – Graduate Course
Management, and Policy 152 – Graduate Student
Academic Considerations and Appeals
6. Student
Email Accounts
The University has initiated a policy by which
all students are required to have a Ryerson University email account. Students will be requested to activate their
account at the start of the academic year and all notices and announcements of
an official nature will be sent via this account.
7.
Student Accommodations
Students are required to immediately inform their instructors of
any situation which arises during the semester, which may have an adverse
effect upon their academic performance, and must request any considerations and
accommodations according to the relevant policies and well in advance. Failure to do so will jeopardize any academic
appeals.
- Medical certificates – If a student misses the deadline for
submitting an assignment, or the date of an exam or other evaluation
component because of illness, he or she must immediately inform the
instructor and submit a Ryerson Student Medical Certificate AND an
Academic Consideration form within 3 working days of the missed date. Both documents are available at www.ryerson.ca/senate/forms/medical.pdf
- Religious observance – If a student needs accommodation because of
religious observance, he or she must submit a Request for Accommodation of
Student Religious, Aboriginal and Spiritual Observance AND an Academic
Consideration form within the first 2 weeks of the class or, for a final
examination, within 2 weeks of the posting of the examination
schedule. If the
required absence occurs within the first 2 weeks of classes, or the dates
are not known well in advance as they are linked to other conditions,
these forms should be submitted with as much lead time as possible in
advance of the required absence. Both documents are available at http://www.ryerson.ca/senate/forms/relobservforminstr.pdf
- Students who need academic accommodation
support should
register with the Academic Accommodation Support office (formerly called the Access Centre). Before
the first graded work is due, registered students should inform their
instructors through an “Accommodation Form for Professors” that they are
registered with Academic Accommodation Support and what accommodations are
required.
8.
Academic Integrity and Plagiarism
Ryerson’s Policy 60 - Academic Integrity policy,
applies to all students at the University.
The policy and its procedures are triggered in the
event that the there is a suspicion that a student has engaged in a form of academic
misconduct.
Forms of academic misconduct include plagiarism,
cheating, supplying false information to the University, and other acts. The most common form of academic misconduct
is plagiarism. Plagiarism is a serious
academic offence and penalties can be severe.
In any academic exercise, plagiarism occurs when one offers as one’s own
work the words, data, ideas, arguments, calculations, designs or productions of
another without appropriate attribution or when one allows one’s work to be
copied.
All academic work must be submitted using the
citation style approved by the instructor. Students may refer to the Ryerson
Library’s list of Citations and Style Guides for more information.
It is assumed that all examinations and work submitted for
evaluation and course credit will be the product of individual effort, except
in the case of group projects arranged for and approved by the course
instructor. Submitting the same work to more than one course, without instructor
approval, is also considered a form of plagiarism.
Students are advised that suspicions of academic
misconduct may be referred to the Academic Integrity Office (AIO). Students who are found to have committed academic
misconduct will have a Disciplinary Notation (DN) placed on their academic
record (not on their transcript) and will be assigned one or more of the
following penalties:
·
A grade
reduction for the work, include a grade of zero for the work.
·
A grade reduction
in the course greater than a zero on the work.
(Note that this penalty can only be applied to course components worth
10% or less, that any additional penalty cannot exceed 10% of the final course
grade, and that information explaining that such a penalty will be assigned
must be included on the course outline.)
·
An F in the
course
·
More serious
penalties up to and including expulsion from the University
For more detailed information on these issues,
please refer to the full online text for the Ryerson Senate Policy 60: Academic
Integrity. For more information on how to avoid academic
misconduct situations, for clues and tips, visit the Academic Integrity website.
