BEFORE YOU BEGIN . . .
The Industrial Fiber Optics IF-DS100G,
Fiber Optic Demonstration System
is a
modular 10-day introduction to fiber optics. It is designed for science, physics,
industrial technology, and vocational education classrooms for grades 6-12. This
module is a complete curriculum—no additional manuals or books are required except
in completing homework assignments, where the library and Internet are adequate.
This manual is an integral part of the IF-DS100G module. It will guide instructors
and students through 10 separate activities each of which has reading assignments
containing background knowledge and fiber optic theory, lab exercises where one
works with fiber optics, worksheets containing questions and homework
assignments. At the rear of this manual is an operational and reference guide for the
equipment.
As you complete this module, you may be surprised with what constitutes fiber
optics. In fact, some of this material contained herein, you may have learned about in
other classes or modules. You will learn that fiber optics is not an entirely new
technology but rather a combination of three technologies: optics, lasers and
electronics. A fiber optic communication system is composed of an optical fiber,
transmitter and receiver. The optical fiber is a spin-off of classical optical study.
Transmitters and receivers are made from semiconductor materials and technology,
making them part of the electronics field. The transmitters of most fiber optic systems
use light emitting diodes (LED’s) or semiconductor laser diodes. The semiconductor
laser is also laser technology and therefore is part of the both electronic and laser field.
The curriculum in this manual will cover all the above aspects and have you working
with the elements in the matching fiber optic hardware.
Everyone who samples or completes these activities will see fiber optics applied
to everyday things and will have a much better appreciation of this new and exciting
technology. Please take time to browse through this manual carefully. It contains a
wealth of information such as reference materials, vocabulary, advance courses, etc.
