Fiber optic technology has developed tremendously in the past few years, and we use it in daily life without even realizing it. Today, this technology is mainly used in telecommunications and the Internet to send or receive information digitally. But  there’s more to the story:

The First Use Of Optical Fibers

Optical fiber was first used in telephony and revolutionized long-distance calls. It made eavesdropping more difficult and significantly reduced interference. As a result, the military realized that they were of great use for their various applications. They are more efficient, offer better throughput and additional security for their data. Moreover, fiber optic cables are strong and portable and easily modified by a wire stripper tool. These characteristics have made optical fiber the first choice for various military applications requiring quality equipment.

In The Field Of Telecommunications 

Optical fiber is used for the transmission of information in telecommunications, whether telephone conversations, images, or data. This is undoubtedly one of the areas in which optical fiber is the most important and has the most future. The fibers are now used in particular for high-speed networks. Their transmission capacities reach one gigabit per second with very low attenuation. Today, thanks to multiplexing, we have hundreds of Gbits / s.

In the field of medicine

The first large-scale use of optical fiber was in medicine and it is still widely used today. It is used medicinally both to diagnose health problems and to treat certain illnesses. For diagnostics, a fiber optic cable carries light inside the body, this light is reflected by internal organs and is picked up by another fiber optic cable that carries this light to a video imaging system. Therefore, it is possible to have a high-quality overview of what is happening in the body in real-time. An example of this use is the endoscope, particularly used in gastroenterology.

Today With Local networks (LANs) 

A LAN is a network of computer equipment connected to each other and sharing data and shared programs. These systems are often used in schools, offices, companies, and factories requiring a professional and quality network.

LAN Networks In Companies

More and more companies are asking for optical applications when they move into new premises. Some companies would not hesitate to pay more to benefit from a faster and more efficient network.

It is all the more reassuring as the fibers conduct light and not electricity, which prevents fire risk linked to the wiring.

Optical LANs make it possible to :


  • Speed up Internet connections and fax systems, 
  • Acquire a visual communication system and more telephone lines, 
  • Send digital information, and to secure data.


Fiber LAN Networks In Schools

Thanks to local networks and optical fiber, schooling is simplified: everything works faster. Students, as well as professors, can carry out research without having to go to libraries as lessons can be sent to a shared server or a website. Moreover,  it is possible to add other computer equipment such as computers, scanners, and modems to LAN networks with fiber optic cable.

These networks make it possible to save money in the long term, centralize information, and simplify life within institutions.

LAN Networks In Industrial Complexes

In this type of environment, communication must be fast and of good quality. For example, to monitor online processes, industries require fiber optic installations to link their control systems to their computer network.


Optical fibers have physical properties that allow them to operate in harsh environments such as factories or warehouses, where temperatures are sometimes extreme, and power outages are common. Optical cables have high speed, can transmit information over impressive distances, and are theoretically immune to interference.

By providing fiber optic LAN networks, you can achieve almost endless transmission of information. They increase the productivity of companies, provide comfort to employees, and boost networks.

Final Words

Apart from the above uses, today, one can see the fiber optics applications in the transport system.  Tolls, traffic lights, and traffic signs require the use of fiber optics. There are also solar optical fibers that are used to conduct light. Also, optical fiber is necessary for the operation of HD television as well as 3D content. All and all, optical fiber has become essential in all fields and sectors of activity.
