Since 1957, Charles Kao has been engaged in research on the application of optical fibers in the field of communications. In 1964, he proposed to replace the current with light and the wire with glass fiber in the ** network. In 1965, in an article based on countless experiments, it was proposed that the use of quartz-based glass fiber for long-range information transmission would bring about a revolution in the communication industry, and proposed that when the glass fiber loss rate dropped to 20 decibel kilometers, optical fiber communication would be successful.

In 1966, he proposed that optical fiber could be used as a communication medium in the standard laboratory. Charles Kao is awarded 28 patents in the fields of electromagnetic waveguides and ceramic science, including optical fiber manufacturing. As a result of his achievements, more than 1 billion kilometers of fiber optic cables have been delivered at lightning speed over broadband internet, providing data to offices and homes around the world.

The theory he proposed.

The invention should not be said yet, but it is due to him.

Charles Kao is a Chinese-American expert in optical fiber communication, and has made major inventions and creations in the revolution of optical fiber communication technology. As early as 1966, when everyone believed that the main use of glass was in the manufacture of everyday utensils, Charles Kao published the basic theory of using extremely high purity glass as a medium to transmit light waves for communication. According to his theory, a hair-thin optical fiber could transmit information at a speed equal to that of a bundle of copper wires as thick as a dinner table, and Kao's theory of optical fiber was considered impossible by experts at the time.

It was not until 1981 that the first optical fiber system was launched, and Charles Kao was named the "father of optical fiber". Today, citizens are able to enjoy long-distance communication with clear voices, and use ICQ and e-mail to communicate with relatives and friends in real time, all through the medium of fibre optics. What is the contribution of optical fiberNow information technology is advancing rapidly, the Internet is very popular, I think many students are also using broadband networks to ** this web page.

The development of optical fiber technology is an important part of the fast and accurate transmission of information. What exactly is fiber optics? How does it deliver its message?

The invention of fiber optic technology was very influential, and if he hadn't invented it at the time, he wouldn't have the inter he has today. Today, citizens are able to enjoy long-distance communication with clear voices, and use ICQ and email to communicate with relatives and friends in real time, all through the medium of fibre optics. Fiber optics not only create inter, but most importantly improve people's lives.

Inter connects people and shortens the distance between them. The entire movie can be streamed to your home TV in just a second; Even a single fiber can hold 24,000 doors** at a time. The light guide system developed by Bell Laboratories has revolutionized the transmission of information by combining sound, analogue data, digital data, video** and a variety of video services.

Charles Kao proposed the theory of fiber optic communication when he was at the British International Telegraph Company. At that time, it was still not recognized.

Because he told others that he wanted to use glass for signal transmission. He traveled to many countries and wanted to make such materials. Because it was thought that pure glass could not be produced. So some even say he's crazy.

It is understandable to deny Kao's argument at the time, when even the most basic lasers were a problem. Not to mention the need for more related sub-devices. No one can do it at all.

Charles Kao has no myths about fibre optic communications. Even the patent for fiber optic communication was not his, it belonged to the company he worked for at the time.

Fiber optic cables are one of the most important inventions of this century. Fiber optic cables use glass as the medium instead of copper, so that a hair-thin version of the optical fiber, its transmission.

The amount of information lost is equivalent to a copper "line" as thick as a dinner table. It has completely changed the mode of human communication, laid the foundation for the current information superhighway, and made the fantasy of "transmitting a set of movies with one line" a reality. The inventor of optical fiber cable is the Chinese scientist Charles Kao, who is known as the "father of optical fiber".

Charles Kao was born in Shanghai in 1933. His father was a lawyer, and his family lived in the French Concession at the time, and he spent his primary school years in Shanghai. As a child, Charles Kao was most interested in chemistry, and he used to make his own fire extinguishers and fireworks.

In 1966, Dr. Charles Kao (1933), a Chinese-American scientist who had worked in the United Kingdom, published the world's first article on optical fiber.

The first "Dielectric Fiber Surface Surface Optical Frequency Waveguide" - written by him and his colleague He Kehan in 1965, has attracted great attention from all over the world. So, he became the "father of fiber optics". Charles Kao.

In 1966, Charles Kao published an article entitled "Optical Frequency Dielectric Fiber Surface Waveguide", which pioneered the basic principle of the application of optical fiber in communication, and described the structure and material properties of insulating fibers required for long-range and high-information optical communication. To put it simply, as long as the purity and composition of glass are solved, it is possible to use glass to make optical fibers and transmit information efficiently. After this idea was proposed, some people called it incredible, and some people praised it.

But in the midst of the debate, Kao's vision gradually became a reality: optical fibers made of quartz glass became more and more widely used, and a revolution in optical fiber communication was set off around the world.

Charles Kao played a leading role in the early days of optical communications engineering and commercial realization. In 1969, Charles Kao measured the inherent loss of 4 dB kilometers of molten silica, which was the first evidence of the effectiveness of ultra-clear glass in transmitting signals. As a result of his efforts, in 1971, the world's first 1-kilometer-long optical fiber was introduced, and the first optical fiber communication system was put into operation in 1981.

Optical fiber can really transmit signals over long distances, and he is one of the founders. At that time, Charles Kao theoretically demonstrated that the loss of optical fiber could be reduced to a very low level, and then the signal could be transmitted over a long distance. This is a pioneering work, and all technologies related to optical fiber communication are now inseparable from Charles Kao's research work.

Dr Charles Kao received the Nobel Prize in Physics.

In 2009, Charles Kao was awarded the Nobel Prize in Physics for his breakthrough work on "the transport of light in fibers for optical communication".

Fiber optic cables are one of the most important inventions of this century. Optical fiber cables use glass as the medium instead of copper, so that a small optical fiber as thin as a hair can transmit information equivalent to a copper "wire" as thick as a dinner table. It has completely changed the mode of human communication, laid the foundation for the current information superhighway, and made the fantasy of "transmitting a set of movies with one line" a reality.

The inventor of optical fiber cable is the Chinese scientist Charles Kao, who is known as the "father of optical fiber".

In 1966, Charles Kao proposed the bold idea of replacing copper wire with glass: using the clear, transparent nature of glass to use light to transmit signals. His starting point was to improve the traditional communication system so that it could transmit more information and faster.

Many people think this idea is incredible, and even think that there is a problem with Kao's nerves. However, through theoretical research, Charles Kao fully demonstrated the feasibility of optical fibers. However, he also struggled to find the kind of "glass without impurities".

To this end, he went to many glass factories, such as Bell Laboratories in Mei China, Japan and Germany, to discuss glass making methods with people. During that time, he was ridiculed by many people, saying that there is no such thing as glass without impurities. But Kao's confidence has not wavered in the slightest.

He said: All scientists should be stubborn and feel that they are right, otherwise they will not succeed.

Later, he invented quartz glass and created the world's first optical fiber, which shocked the scientific community.

Charles Kao fabricated the world's first optical fiber. Known as the "Father of Optical Fiber".
