20. Optical Fiber Applications
Data Transmission
The main application of fiber optic cable is data transmission in the form of light. At first, the audio, video signals are converted into electronic signal then the electronic signal
converted into light and transmitted through the optical fiber. At the receiver point again light converted into an electronic signal.
Telecommunication
Optical fiber has a big role in data transmission in the telecommunication system. Due to the lighter weight, very high speed, high bandwidth, high accuracy, optical fiber is used
in the telecommunication system.
Medical Industry
Optical fiber is very thin in size, for this reason, it is widely used in the medical industry. Optical fiber can be easily inserted into the hollow space inside the human body. So for
the surgery, microscopy purposes optical fiber is used to transmit the LASER. In bronchoscopes and laparoscopes, optical fiber is used.
Military Communication
Optical fiber cables are also used in the military communication system. Optical fiber provides high security, no electrical or magnetic interference, a high signal quality that is
why optical fiber gives many advantages in the military communication system. The military communication system uses SONAR technology, Hydrophones, etc where optical
fiber cables are used.
Networking
In the long distance and high-speed communication system, the networking devices, computers are connected through the fiber optic cables. Our worldwide INTERNET
connection also uses optical fiber cables to connect all devices across the world. The high speed and worldwide INTERNET connection are available to us for the fiber optic
cable.
Light Distribution
Optical Fiber cable only works with light. So in light distribution purpose, optical fiber is used. In decoration purpose such as artificial Christmas trees, signs, lighting art, logos,
the optical fiber illumination system is used.
Broadcasting
As the fiber optic cable has high data transmission speed and high bandwidth, so it used for television broadcasting system for video and audio signal transmission purpose in
the form of light. There is also an important reason for using optical fiber in broadcasting that is the optical fiber is cheaper and lighter than copper wires.
Inspection
Generally, LASER is used for inspection purpose in heavy engineering. For the inspection of damage in heavy machines, buildings, bridges, etc LASER is used. In these cases,
optical fiber cables are used to carry the LASER lights.
