Fibber optics uses what medium to send informatiion
|
Light
|
|
|
What are the three parts of a fiber optic data link
|
Transmitter, optical fiber, receiver
|
|
|
The fiber optic transmitter has which ofthe following functions?
|
Converts the electrical input signal to an optic l signal
|
|
|
What creates the light in fiber optics?
|
LED and laser diodes are the light source in fiber optics
|
|
|
What does the viber optic receiver do?
|
The optical receiver conters the optical signal back into an electrical signal
|
|
|
What are other components found in fiber optics?
|
Splices, coupleers, and connectors
|
|
|
Light exhibits what kind of wave motion?
|
Transverse
|
|
|
What does a translucent substance do to light rays that fall on it?
|
Reflects AND absorbs them
Ex: frosted glass |
|
|
What happens when light waves fall on an opaque substance?
|
Reflects certain frequencies (color) OR absorbs all wave frequencies (black)
|
|
|
Define refraction.
|
A light wave passes from one mediuminto another medium with a different velocity. As the wave enters the second medium, a change of directiion is apparent
|
|
|
Light is transmitted along an aptical fiber by what two methods
|
Ray theory and mode theory
|
|
|
What are the three basic parts of optical fiber?
|
Core, cladding, and coating
|
|
|
What are the two basic types of fiber?
|
Single mode, multimode
|
|
|
Define attenuation.
|
The loss of optical power as light travels along a fiber
|
|
|
Describe two characteristics of single mode.
|
Lowest signal loss and the highest bandwidth
|
|
|
What is chromatic (Intramodal) dispersion
|
When dispersion is caused by different colors of light travel ing through the fiber at different speeds
|
|
|
Which low density fiber cable designs are preferred for Navy ship-board use?
|
OFCC cable is preferred for Navy shipboard use because of its ease of handling and ruggedness
|
|
