prepare a report about various uses of optical fibers in your daily life
Answers
Answer:
1. Total internal reflection is the basic principle behind working of an optical fiber.
2. An optical fiber is a very thin fiber made of glass or plastic having the radius about a 10-6 meter.
3. A bunch of such thin fibers forms a light pipe.
Working:-
1. Because of a small radius of the fiber, a light goes into it makes a nearly glancing incidence on the wall.
2. The angle of incidence is greater than the critical angle and hence total internal reflection takes place.
3. The light is thus transmitted along the fiber.
Uses:-
1. Optical fibers are used in endoscopy to see the internal organs of our body.
2. Optical fibers are used in transmitting communication signals through light pipes.
3. Optical fibers are used in international telephone cables laid under the sea, in a large computer network, etc.
4. Optical fibers are used in photometric sensors to measuring blood flow in the heart.
Answer:
Fibre optic cables are cables that contain several thousands of optical fibres in a protective, insulated jacket. The optical fibres are very thin strands of pure glass, which transmit information in the form of light. Fibre optic cables have revolutionized the world of network communication ever since their inception nearly four decades ago. Today, these cables have almost obliterated traditional methods of networking, which use metallic wires. Some of the most popular uses of fibre optic cables are listed below.
Internet
Fibre optic cables transmit large amounts of data at very high speeds. This technology is therefore widely used in internet cables. As compared to traditional copper wires, fibre optic cables are less bulky, lighter, more flexible, and carry more data.
Computer Networking
Networking between computers in a single building or across nearby structures is made easier and faster with the use of fibre optic cables. Users can see a marked decrease in the time it takes to transfer files and information across networks
Surgery and Dentistry
Fibre optic cables are widely used in the fields of medicine and research. Optical communication is an important part of non-intrusive surgical methods, popularly known as endoscopy. In such applications, a minute, bright light is used to light up the surgery area within the body, making it possible to reduce the number and size of incisions made. Fibre optics are also used in microscopy and biomedical research.
Automotive Industry
Fibre optic cables play an important role in the lighting and safety features of present-day automobiles. They are widely used in lighting, both in the interior and exterior of vehicles. Because of its ability to conserve space and provide superior lighting, fibre optics are used in more vehicles every day. Also, fibre optic cables can transmit signals between different parts of the vehicle at lightning speed. This makes them invaluable in the use of safety applications such as traction control and airbags.
Telephone
Calling telephones within or outside the country has never been so easy. With the use of fibre optic communication, you can connect faster and have clear conversations without any lag on either side.
Lighting and Decorations
The use of fibre optics in the area of decorative illumination has also grown over the years. Fibre optic cables provide an easy, economical and attractive solution to lighting projects. As a result, they are widely used in lighting decorations and illuminated Christmas trees.
Mechanical Inspections
Fibre optic cables are widely used in the inspection of hard-to-reach places. Some such applications are on-site inspections for engineers and also inspection of pipes for plumbers.
Cable Television
The use of fibre optic cables in the transmission of cable signals has grown explosively over the years. These cables are ideal for transmitting signals for high definition televisions because they have greater bandwidth and speed. Also, fibre optic cables are cheaper as compared to the same quantity of copper wire.
Military and Space Applications
With the high level of data security required in military and aerospace applications, fibre optic cables offer the ideal solution for data transmission in these areas.
Fibre optic cables have an array of uses that go beyond what most people are aware of. You could have been using them all along and not have even known!
