FIBER OPTIC
COMMUNICATION SYSTEMS

SYNOPSIS


"Fiber Optics Communication Systems" is designed for engineersand managers who have a general background in electronics but who have nothad formal course work in optics or practical hands-on experience with opticalor fiber optics systems.

ELIGIBILITY REQUIREMENTS


Engineers, engineering managers, junior professionals and also specifiedtechnicians with an electronics background and basic engineering mathematics.

LEARNING OBJECTIVES


The principal objective of the course is to acquaint technical personnelhaving responsibilities involving the design, installation, or maintenanceof fiber optics systems with the principles and techniques of fiber optics.

The learning objectives of the course are to:


COURSE DESCRIPTION

Fiber optic communication systems have evolved at an exponential ratesince the first low-loss fibers were introduced in 1979. Operational fibersystems are now common place, particularly in modern phone communicationsystems throughout the world. Almost daily, new and innovative applicationsof fiber optics technology are being introduced.

As an introductory course, there are no requirements for the studenttaking this course to be knowledgeable in optics, fiber optics or communications.Only simple algebra and trigonometry are used in explaining the characteristicsof these systems and components. Those attending the course will be ableto design and specify functional fiber optic communication systems and toevaluate system components to meet a specific performance level. The studentswill also learn to evaluate fiber cables, light sources, detectors and couplersfor use in their applications. Furthermore, from the techniques presented,the student will gain skills in evaluating commercially available subsystems,such as transmitters and receivers, for use in their applications.

Where desirable, the course can be augmented with a hands-on laboratoryfor design of fiber optics communications systems.
