2. What are Fiver Optics?
(Summary) part 1
● Fiver Optics(optical fibers) are long, thin strands of very pure
glass about the diameter of a human hair.
They are arranged in bundles called optical cables and used
to transmit light signals over long distances.
● The light in a fiber-optic cable travels through the core
(hallway) by constantly bouncing from the cladding (mirror-
lined walls), a principle called total internal reflection.
3. What are Fiver Optics?
(Summary) part 2
● Optical fibers are made of extremely pure optical glass, and
the the glass in an optical fiber has far fewer impurities than
window-pane glass.
● Optical fiber cables can withstand 100,000 lb/in2 or more, so
Optical fiber cables are strong and flexible.
4. Q1. Choose 5 key words from the article
on which you made the presentation.
● Strands of Very Pure Glass
● Total Internal Reflection
● Morse Code
● Light Signals
● Special Coating (Doping)
5. Q2. Choose 3 sentences from the article that
are very important for understanding the
concept described in the article.
● Fiber-optic lines are strands of optically pure glass as thin as
a human hair that carry digital information over long
distances.
● The light in a fiber-optic cable travels through the core
(hallway) by constantly bouncing from the cladding (mirror-
lined walls), a principle called total internal reflection.
● Because the cladding does not absorb any light from the
core, the light wave can travel great distances.
6. Q3. Why are these sentences
important?
● These sentences are explain the mechanism of the
optical fiber easily and simply for me. I can know
how Fiber-Optics working when I read these
sentences.
