Garth Naar - Applications of Fiber Optic Cable

Around 4 decades ago, fiber optic cable brought earthshaking changes to the world, especially for the telecommunication industry. Optic fiber cable has right advantage compared to copper cable in terms of bandwidth, distance, security, reliability and etc. Fiber cables, made of very thin strands of pure glass, can travel between 984.2 ft to 24.8 miles while the maximum transmission distance is 9,328 ft. Nowadays, the common fiber cables are use metallic wires instead of traditional approaches of wiring. And they have been applied to many industries, which are mainly described as the following.

Computer Networking

Garth Naar says Using fiber optic cables, data transformation between computers in one same building or some nearby places become faster and easier than copper medium. This make computer network users can receive and read information and files just a few seconds, which incredibly saved time and enhanced efficiency.

Cable Television

Over the years, optical fiber cables are widely applied to cable television from the aspect of speed and price. With the higher and great bandwidth and speed, the optical fiber cables are optimal solutions for high definition televisions. Besides, the fiber cables are cost effective choices compared to the same quantity of copper wire.


Unlike copper cable, fiber optic cables are less bulky, more flexible and carry more data. They can transmit large amounts of data at very high speeds. Therefore, they have been extensively used in Internet cables.


Decades ago, we could only communicates with each other by letters, telegraphs, walkie-talkies, that is too time-consuming and would sometimes cause some irreparable losses for the sake of timeliness. By using fiber optic communication, we could talk to anybody at anywhere we like without any delay. We can receive and transmit our information simultaneously. This effectively improved our time on communication.

Mechanical Inspections

Garth Naar says Optical fiber cables can also be deployed into inspection of hard-to-reach places. They are especially applied to on-site inspections for engineers as well as inspection of pipes for plumbers.

Surgery and Dentistry

In the field of medicine and research, you would also find the traces of fiber optic cables. Besides, they are widely applied to microscopy and biomedical researched as well. As an paramount part of non-intrusive surgical methods (also known as endoscopy). In the process of such kind of surgery, bright light is used to lighten the wound on the body. In this way, the number and size of incisions could be possibly reduced.

Military and Space Applications

Data security and confidentiality attach great importance to military and aerospace applications, fiber optic cables provide an ideal solution for data transmission in these areas.

Automotive Industry

In the field of automotive industry, fiber optic cables mainly function in the lighting and safety parts. With their superior lighting and narrow spacing, fiber optic cables are widely used in lighting in automotive industry, both in the interior and exterior of vehicles. Moreover, fiber optic cables can transmit signals between different parts of the vehicle at lightning speed and have been deployed in many other vehicles as well, especially the vehicles related to lighting. This attaches great importance in the use of safety applications such as traction control and airbags.
