Educational Fiber Optics
Speed of Light Apparatus
Centuries of scientific learning culminate in this low-cost
yet ingenious system which teaches students how to measure the
speed of light and to understand the "why" of their learning.
In operation, the system utilizes an oscilloscope to monitor
a light pulse in its passage between a transmitter and
receiver, coupled with 20 meters of fiber optic cable. At the receiver,
the oscilloscope displays the phase delay and basis for the
calculations which will determine the speed of light through the fiber.
An integral companion to the electronic and physical
components is an easily understood and often lighthearted manual which traces
the steps of pioneers in optics research. Assembly instructions are
included for those who purchase the Apparatus in kit form.
The Apparatus can be assembled in only a few moments for
student's use, but the curriculum first offers a fascinating academic journey
through the years of discovery leading to modern-day breakthroughs in
optics technology and to today's frontiers.
The Apparatus consists of an electronics circuit board in a
protective plastic en-closure, two fiber optic cables, test connections for all
outputs and a 110V AC-to-DC power adapter. The optical fibers terminate
in simple cinch connectors for easy assembly and efficient coupling.
A 20MHz dual-trace oscilloscope is required.

Fiber Optic Courses
Intermediate Fiber Optic Classroom & Lab Course

An advanced fiber optics curriculum, for industrial arts, vocational school and university
levels. Courses can be tailored in length from 10 to 15 weeks. Recommended prerequisites: a
basic understanding of electronics and mathematics. Course includes a text for classroom
or lecture, lab course containing a comprehensive series of student experiments and lab kit
with all required components.
Part One of the classroom text places fiber optics into perspective as a transmission
medium and describes its advantages over other media. Part Two examines fiber sources,
detectors and connectors, in contrast to the distinctly different characteristics of their
electronic counterparts. Part Three explains in detail how fiber optic systems are assembled. It covers
link system design, installation, special fiber optic hardware, applications and
equipment.
"Instructor's Edition" contains the items above, plus an answer guide, different types of
optical cable, image guides, LEDs and detectors.

Introduction
These devices are in Industrial Fiber Optics' family of low-cost, medium-frequency,
short-distance fiber optic emitters and detectors.
Each emitter and detector consists of a PVC housing, an internal active element such as
an LED or photodetector and a cinch nut to hold the fiber in place. The PVC housing retains
the active element and the cinch nut while optimizing coupling between the active
element and the jacketed 1000 µm plastic fiber.
Working with this family of fiber optics is simple:
No special tools or training required. Only a sharp knife or razor blade is needed
to terminate the plastic fiber. When the fiber is inserted in the emitter or detector, tighten
the cinch nut. Thereafter, the fiber can be
removed simply by loosening the nut.
The IF-95T contains a photologic detector with
a totem-pole output and the 95OC is a similar detector with an open-collector option.
Both versions contain an IC with a photodiode,
linear amplifier, voltage regulator, and Schmitt trigger.
The devices feature TTL/CMOS compatible logic level output which can drive upto 5 TTL
over supply voltages ranging from 4.5 to 16 volts.

Fiber termination instructions:
- Cut off the ends of the cable with a single-edge razor
blade or sharp knife. Try to obtain a precise 90-degree
angle (square).
- Insert the fiber through the locking nut and into the
connector until the core tip seats against the internal micro-lens.
- Screw the connector locking nut down to a snug
fit, locking the fiber in place.
