What Is Fiber Optics ?
• Transmitting
communications
signals over hair thin
strands of glass or
plastic
• Not a "new" technology
• Concept a century old
• Used commercially
since 1980
©2019, The Fiber Optic Association, Inc.
Why Fiber Optics?
Fiber is the least
expensive, most
reliable method
for high speed
and long distance
communications
AT&T promotional
photo from 1970s
Fiber Is Everywhere!
It’s how we communicate…

Fiber Optic Applications
• Fiber is the least expensive, most reliable
method for high speed and/or long distance
communications
• While we already transmit signals at 100
Gigabits per second speeds, we have only
started to utilize the potential bandwidth of
fiber
©2019, The Fiber Optic Association, Inc.
Fiber Optic Applications
• Outside Plant vs Premises Installations
©2019, The Fiber Optic Association, Inc.
Fiber Technology
A glass optical fiber is about twice
the size of a human hair.
©2019, The Fiber Optic Association, Inc.
Fiber Technology
Fiber uses reflection (L) to
contain light inside the core
of the fiber (below).

Light Used In Fiber Optics
• Fiber optic systems transmit using
infrared light, invisible to the human
eye, because it goes further in the
optical fiber at those wavelengths.
©2019, The Fiber Optic Association, Inc.
Wavelength-Division Multiplexing
Allows Transmitting Multiple Signals
©2019, The Fiber Optic Association, Inc.
Fiber Optic Cable
• Protects the fibers
wherever they are
installed
• May have 1 to >1000
fibers
©2019, The Fiber Optic Association, Inc.
Fiber Optic Connectors
• Terminates the fibers
• Connects to other fibers or transmission
equipment
©2019, The Fiber Optic Association, Inc.
Jobs In Fiber Optics
• Designing components
• Manufacturing fiber, lasers, etc.
• Designing systems
• Installing networks
• Training and teaching
