And Answers 100% Correct
Medium used to send information - ANSWER - light
What are the four parts of a fiber optic data link - ANSWER - transmitter, optical
fiber, connectors/splices, receiver
fiber optic transmitter has which of the following functions - ANSWER - converts the
electrical input signal to an optical signal
Fiber optic systems used what three type of optical sources - ANSWER - LEDs,
lasers, VCSEL(vertical cavity surface emitting lasers)
fiber optic receiver performs which of the following functions? - ANSWER - converts
the optical signal back into an electrical signal
What are the two type of optical detectors - ANSWER - PIN photodiodes and APDs
advantages of fiber optics - ANSWER - increased bandwidth, lower signal
attenuation, reduced size and weight
To describe the nature of light, which of the following ways can be used - ANSWER -
electromagnetic wave and particles of energy
Light exhibits what kind of wave motion - ANSWER - transverse
description of the factors of transverse wave motion? - ANSWER - wave magnitude
varies perpendicular to the wave motion direction
, What does a transparent substance do to light rays that fall on it - ANSWER -
transmits
example of translucent substance - ANSWER - frosted glass or oiled paper
what does opaque surface do when light rays fall on it - ANSWER - reflects or
absorbs
example of opaque surface - ANSWER - cardboard
example of luminous source - ANSWER - sun, flashlight, gas flame. any object can
be luminous if it omits it's own light
light waves that strike surface but neither transmitted or absorbed - ANSWER -
Refracted
law that states "angle of incident equal the angle of reflection - ANSWER - law of
reflection
A light wave is incident on a surface. The reflected power is the greatest in which of
the following incidences? - ANSWER - almost parallel
If a light wave passes from a less dense medium to a denser medium, how does the
angle of refraction compare to the angle of incidence? - ANSWER - Less than angle
of incidence
another word for diffuse - ANSWER - scattered
what happens when light falls on black piece of paper - ANSWER - absorbs
two methods light is transmitted through fiber - ANSWER - ray and mode theory
