Characteristics
What is the Fiber Optic cable constructed of?
Glass
The two characteristics of all wave forms
What is amplitude and wavelength (frequency)?
The outside covering of a fiber optic cable
What is the jacket?
ST - ST, SC - SC, ST - SC
What are fiber optic patch cords?
The loss of energy in a signal (caused by scattering, dispersion, extrinsic losses)
What is attenuation?
Put these values in order from largest to smallest
nanometer, millimeter and micrometer
This device sends information at the source
Where is the transmitter?
The electromagnetic spectrum holds all wavelengths of light (name two)
What is Visible light, infrared, gamma rays, x-rays, radio, sound, cosmic rays, ultraviolet, television, subsonic?
The interior of the single cable from inside out {Hint C C}
What is the core and cladding?
This devices cuts off the jacket
What is the jacket cutter?
Unit of measurement of signal strength
What is a Decibel?
Say 3,400,000,000 in scientific notation
What is
3.4 x 10^9
Unlike copper cables which are sensitive to Electromagnetic Interference, these cables are not
What are Fiber Optic cables?
The larger the wavelength the __________ frequency; the smaller the wavelength the _______ the frequency.
What is smaller, larger? (inversely proportional)
This tool lets us see the core and cladding in large scale for identification defects.
What is a microscope?
This device strips the covering off the cladding and core?
What is a stripper?
(Spreading) Distortion of light wave as it reflects off and through the cladding (when the cable is bent and light transmits out)
What is modal dispersion?
Log_10 (10,000)
What is 4?
This distance is 62 miles (100 km) for Single Mode and 1.2 miles (2 km) multimode fiber optic cable.
What is the maximum distance?
When an incident ray of light reflects off a surface (mirror), it approaches at this angle.
What is the angle of incidence?
A continuity test is performed with this device which transmits light through the core.
What is the spot?
This tool trims the end of the fiber after its glued into the connector
When a light source enters this region and achieves total internal reflection
What is the cone of acceptance?
This number of decibels represents a 50% loss in signal strength
What is 3 decibels (db)?
Although we see visible light, the Telecommunication companies use this light to transmit the day signal through fiber optic cables.
What is infrared light?
This characteristic of light is associated with Intensity, which is the signal strength.
What is amplitude?
Fiber optic end is polished with this hand motion using this many grades of film (sand paper)
What is figure 8 and 4?
What is the purpose of the boot?
The stepped index fiber has a higher index of refraction here
What is the cladding? The cladding has a higher index of refraction that the core.
At 6 decibel attenuation, the source of light has this amount of energy remaining
What is 25%?
It is defined in two ways 1) how much data in Mbs you purchase or 2) which frequency band is the signal transmitted.
What is bandwidth?
A prism separates visible light into a rainbow of colors because the light speed does this in a substance.
What is slow down?
When the source is one laser or multiple beams of light.
What is single-mode and multimode?
In order to polish the end of the fiber we use this metal device.
What is the puck?
850nm, 1350nm
What is wavelength of the transmitted signal?
The index of refraction for diamonds is 2.417 and the speed of light through it is
1.24 xx 10^6
What is the speed of light or
3.0 xx 10^6
