and Answers All Correct
Fiber optic transmissions are not susceptible to - Answer- interruption or distortion by
electrical noise

An advantage of fiber optics is that they can ____________ of data - Answer- carry high
frequencies

Concerning security, fiber optics - Answer- cannot be tapped without physically
disrupting the service

A basic fiber optics communication system is made up of - Answer- Fiber optic cable,
fiber optic strand, transmitter, receiver, and connectors

Very small core fibers work best with __________ which can supply narrow beams of
light. - Answer- laser diodes

LED's operate at - Answer- slower transmission speeds.

Two key concepts in the study of light transmission are - Answer- Signal propagation
and signal attenuation

The ________ of a material is the ratio of the speed of light in a vacuum compared to
the speed of light in a certain material. - Answer- refractive index

The refractive index is always - Answer- greater than 1

The angle at which the light enters the material is - Answer- incidence

The angle at which light exits the material is - Answer- refraction

Light rays entering a fiber at an angle above a certain value will be accepted and guided
within the core of the fiber, this angle is known as - Answer- the acceptance angle

The ___________ is the range of angles over which the system can accept or emit light
- Answer- numerical aperture

The single major factor in signal attenuation is the - Answer- wavelength

Each fiber optic fiber has a characteristic attenuation that is measured in - Answer-
decibels

, The spreading out of the signal is known as - Answer- pulse dispersion

As fiber length increases, both - Answer- data rate and bandwidth decrease

Major factors in fiber optics are - Answer- speed, capacity, and proper alignment

The appeal of fiber to the telecommunication industry is not the low attenuation, but the
- Answer- high-speed transmission capabilities

Most fibers have an additional coating around the cladding called a - Answer- buffer

Light in high-order modes is more apt to be lost due to imperfections like
_______,________, and______ in the fiber - Answer- connector separations,
misalignments, or sharp bends

The three most common fiber materials are - Answer- glass, plastic, and silica

Compared with other fibers, plastic fibers are - Answer- limited in loss and bandwidth

_______ is a term used in electronics to indicate one way transmission. - Answer-
Simplex

The cable is underwater, including transoceanic applications - Answer- submarine

Similar to direct burial, but the cable is inside a duct or conduit - Answer- indirect burial

The device used to convert a light signal into an electrical signal at the receiver is
known as a(n) - Answer- Photosensitive detector

Signal propagation is defined as________. - Answer- the characteristic movement of a
light signal through a medium

The value that represents the amount of light lost within a fiber optic system is _______.
- Answer- attentuation

The two basic components of an optical fiber are the ________. - Answer- core and
cladding

The term used when there are several paths through which light can travel in an optical
fiber is ________. - Answer- multi-mode

A mode is defined as __________. - Answer- one path a light ray can travel through a
material.
