Fiber Optics
Fiber is the science of...
What is transmitting light through glass or plastic fibers.
a device used to transmit voice waves
What is a Photophone
The ratio of the speed of light in a vacuum compared to the speed of light in a certain material
What is the Refraction index
What does a fiber compare to
What is a human hair
What are the three different types of light emitters commonly used
What are Edge-Emitting Laser Diodes, VCSELs, and Light-Emitting Diodes
This outer layer effectively contains light, reflecting it back into the optical fiber's core
What is Cladding
When was the Photophone invented
What is 1880
Two main sections of an optical cable
The inner core and the cladding
The main components of a fiber cable
What are the Optical Fiber, Buffer, Strength Members, and Jacket
Two key concepts of Light Transmission
What are Signal Propagation and Signal Attenuation
Two factors to consider when selecting fiber optic cable
What are distance and the amount of information to be transmitted
What was used to modulate a beam of light in a Photophone
What is a mirror
What are the three major considerations for operation of fiber optic systems
What are Speed, Capacity, and Proper Alignment
The common strength members of fiber optic cable
What are Kevlar, Steel, and Fiberglass Epoxy Rods
The range of angles over which the system can accept or emit light
What is a numerical Aperture
Basic parts of a basic fiber optic system
What is Fiber Optic Cable, Fiber Optic Strand, Transmitter, Receiver, and Connectors
What was carried on the beam of light in a Photophone
What are Sound Waves
Where can signal losses in fiber optic be significant
What are at the Connectors, Splitters, Light Source Connections, and Splices
Simplex, Duplex, Multi-fiber, Heavy-duty, Light-duty and Plenum duty, and Undercarpet are types of
What are Indoor Cables
LASER is the acronym for
What is Light Amplification by Stimulated Emission of Radiation
The process of directing light into the optical fiber
What is Light Coupling
True or false - is what Bell created the same as fiber optics today
What is false. It is not the same as modern fiber optics
The additional coating around the cladding and what it does
What is the buffer. It protects the fiber from shocks that might affect its optical or physical properties
Where are outdoor cables used
What are Ariel Runs, Direct Burial, Indirect Burial, and Submarine
What does an active splitter consist of
What are a Light Source, Photodetector, Beam Divider, Focusing Mirror, and Pigtailed Fiber
