What is needed for termination work? (NC set: fiber optics)
Plenty of slack
-
What is the color measure of light which travels quicker in a vacuum? (NC set: fiber optics)
The nanometer
-
Regarding single mode and multi mode fiber optic cables what are their core sizes resulting in what acceptable transmission lengths of what type? (NC set: fiber optics) Single mode: has a small core resulting in long transmissions
multimode: has a large core resulting in short transmissions
-
The core of a fiber-optic cable is also referred to as what? Lets in how much light? (NC set: fiber optics)
Numerical aperture, letting in 80% of light.
-
What three elements create losses in fiber-optic cables and connections? (NC set: fiber optics)
Bending, connectors, and splices.
-
Shorter wavelengths are absorbed in what? The solution to this problem is what? (NC set: fiber optics)
-
What is also known as signal loss? (NC set: fiber optics)
Attenuation
-
What is the advantage of using fiber-optic connections versus co-axle? (NC set: fiber optics)
Fiber optics have a higher bandwidth: higher frequency of 300 MHz over 200 km between transmission sites versus 700m for coaxial
-
List several advantages of fiber optics. (NC set: fiber optics)
Transmission length, smaller size, security: not easily read unless cut open, explosion resistant: does not transmit heat, noncorrosive:
-
Fan out regarding fiber optics refers to what? (NC set: fiber optics)
The process of making fiber optics bigger for connections
-
Fiber-optic cables single mode, multimode, and outdoor are identified by what color on the outer jacket? (NC set: fiber optics)
- Single mode – yellow
- multimode – orange
- outdoor – black
-
Outdoor fiber-optic cable identified by a black outer jacket can be ran how far into a building before it needs to be ran in conduit, spliced, or terminated? (NC set: fiber optics)
50 feet
-
The industry-standard for fiber-optic cable left for termination at a data rack or other locations is what length? (NC set: fiber optics)
25 feet coiled +10 feet to terminate
-
OTR is a test to test fiber optics through how many feet or more and with what kind of splice? (NC set: fiber optics)
100 feet or more with mechanical splice.
-
When making fiber-optic data connections into a data rack how do you clean to remove the gel and what do you apply to aid in moving strands through the connector? (NC set: fiber optics)
Apply alcohol to remove gel and baby powder to aid in moving strands through the connector.
-
Two types of data connections exist what are they? (NC set: fiber optics)
- ST: stab and twist: bigger
- LC: smaller
-
Is interduct needed with MC armored fiber optic cable? (NC set: fiber optics)
No
