Fiber Optical Networks

Fiber Optical Networks

• A review on how fiber optic communication is used
  to create optical fiber networks used by many
  telecommunications companies today

What is a network..?

• In the world of applied science and engineering,
  fiber optical cables are among one of the most
  interesting and most advanced forms used for
  communication, and also one of the fastest. In
  order to understand how fiber optics work you
  must learn what a a network is first.

3
A Network Is..?

• In simple terms, a network refers to any
  interconnected system or group, and are a key
  link in the world of technology.

4
OPTICAL FIBRES ARE

• Thin pieces of glass or plastic fiber which are
  designed using the transmission of light guided
  along transparent fibers, using reflection as a
  means of transporting information, images etc.
  Optical Fibers are NOT electric in nature.

History Of Fiber Optics In Technology

• Fiber Optics appeared in the technology world in
  the 1970s, first being used for the transmission
  of images and later applied for use in internal
  medical examinations among other things. Lowered
  attenuations in fiber optic cables resulted in
  the internet and other advanced applications of
  fiber optic technology in the following decades.

Relay of Information...

• The process of relaying information through fiber
  optics is a waveguide process, and is quite
  simple...

7
Relay of Communication

• First, you must create an optical transmitter to
  convert an electrical signal into an optical
  signal which is then relayed onto the fiber.
• Semiconductor devices such as LEDs are commonly
  used as transmitters.

8
Relay of Communication

• The signal is relayed and attenuated through the
  fiber optic cable, containing images, text or
  other information. Amplifiers or optical
  regenerators are used along the way to reduce
  distortion and boost light waves.

9
Relay Of Communication

• An optical receiver is then used to receive the
  electric signal and decodes the light signals,
  preparing the information to be interpreted by a
  medium of some sort.
