2. What is Fiber Optic?
An optical fiber is a semi-flexible
transparent, and extremely thin
dimeter of a human hair.
thousands of this strands are
arranged in bundles to make a thicker
cable.
3. A fiber optic cable is made up of five parts.
1-Strands of glass that are connected
together to make channel for light to travel,
this channel is called core.
2-protective sheath of cable contain a
sheath of silica which increases the total
internal reflection of the core to prevent
data loss.
4. 3-third layer is plastic layer which surrounds the
core and make fiber core stronger.
4-fourth layer is a strong layer which give add
support the other coating.
5-all this layers are covered in the cable jacket
like.
5. How it works?
Fiber optic cables send or receive signals using pulses of light
generated by small lasers or LEDs (light-emitting diodes), and
the light travel inside the core.
Fiber optic have two types of cables one of them single mode
another multi mode, single mode fiber uses very thin glass
strands and laser, but multi mode fiber use LEDs.
Fiber optic have higher capacity, which rated at 10Gb/s, 40Gb/s
and even 100Gb/s are standard.
6. 1-Communication:massive amounts of data is sent
and receive over networks of fiber optic cables for
cable television phones and the internet.
2-Medicine:Since these cables are able to bend
doctors use them during surgery to shine light
inside parts of the body which are hard to reach
3-Engineering: fiber optic scopes are also used by
engineers and mechanics to throw light on to parts
of machines with a lot of twists and bends where
lights can’t easily travel.
