A communication system that uses pure glass fibers to transmit digital data is fiber optics.
- True
- False
True
Digital data is sent over beams of light.
- True
- False
True
What is not an advantage of fiber optics?
- EMI Resistant
- Low signal loss
- High temp environments require specialized safeguards/equipment
- Data rate 100 times faster
High temp environments require specialized safeguards/equipment
What is not a disadvantage of fiber optics?
- High vibration requires specialized safeguards/equipment.
- Fragile
- Expensive
- Less weight
Less weight
An advantage of fiber optics is that long runs do not require amplification.
- True
- False
False
Short runs require amplification.
- True
- False
False
Each bend/curve loses some of the signal strength.
- True
- False
True
Which is more refractive?
- Core
- Cladding
Core
Light must be launched at any angle, to successfully refract through the fiber optics.
- True
- False
False
If light is launched straight on, it will fail because it will not refract.
- True
- False
True
Laser light will only damage your eyes if you can see it.
- True
- False
False
White laser light cannot be seen but will damage your eyes.
- True
- False
True
Fiber optics is stated as being made of glass, this glass is tempered glass and does not break.
- True
- False

False
Fiber optic cables have near zero tolerance for unwanted materials; oils, dirt.
- True
- False
True
You can easily inspect the fiber optics with the naked eye.
- True
- False
-False
Using a microscope or magnifier to view the free end of any optical fiber connected to the 180XL is recommended.
- True
- False
False
Always aim the free end of an active fiber at a reflective surface.
- True
- False
False
A flashing red light on the 180XL indicates what?
- laser light is not functioning
- batteries are low
- the 180XL has an internal malfunction
- No answer text is provided
