2. What is Optical Fiber?
3. Advantages of Optical fiber cable

3. What is optical Fiber?
- An optical fiber is a flexible, transparent fiber made by
drawing glass (silica) or plastic to a diameter slightly
thicker than that of a human hair.
- Optical fibers are used most often as a means to transmit
light between the two ends of the fiber and find wide usage
in fiber-optic communications

4. Structure of optical fiber

5. Advantage of optical fiber cable
1) Extremely High Bandwidth :
- Fiber optic cables have a much greater bandwidth than metal
cables.
- Optical fiber has a bandwidth capability of 400MHz/km or
greater.
- Optical fiber can provide data transmission performance up to
10Gbps, 40Gbps and even 100Gbps with new hardware that is
now available.

6. 2) Low Power Loss :
- An optical Fiber offers low power loss. This allows for
longer transmission distances.
- In comparison to copper; in a network, the longest
recommended copper distance is 100m while with fibre, it
is 2000m.
- In order to increase the transmission distance, a repeater
must be installed in the middle of the path to re-generate
the signal
- Optical fiber cable allows data to be sent far without as
many repeater devices that are required by other types of
cabling.

7. 3) Interference :
- Fibre optic cables are immune to electromagnetic
interference.
- It can also be run in electrically noisy environments without
concern as electrical noise will not affect fibre.
- optical fiber transmits light (photons) rather than electrons,
it does not radiate electromagnetic fields, nor is it
susceptible to electromagnetic fields.

8. 4) Size :
- In comparison to copper, a fibre optic cable has nearly 4.5
times as much capacity as the wire cable has and a cross
sectional area that is 30 times less.
5) Weight :
- Fibre optic cables are much thinner and lighter than metal
wires.
- They also occupy less space with cables of the same
information capacity. Lighter weight makes fibre easier to
install.

9. 6) Secure Transmissions :
- optical fiber cabling provides an extremely secure
transmission medium.
- optical fiber is a dielectric, it does not present a spark
hazard.
- fiber optic cabling does not radiate magnetic fields.
- the light (photons) is confined within the fiber which
makes it impossible to tap the signal without cutting into
the fiber.
- fibre is the most secure medium available for carrying
sensitive data.

10. 7) Flexibility :
- An optical fibre has greater tensile strength than copper or
steel fibres of the same diameter. It is flexible, bends
easily and resists most corrosive elements that attack
copper cable.
8) Cost :
- The raw materials for glass are plentiful, unlike copper.
This means glass can be made more cheaply than copper.
