Two types of electromagnetic waves that can travel along an optical fiber are infrared and visible light. These wavelengths are commonly used in fiber optic communication systems for transmitting data over long distances with low signal loss.
Light waves carry optical fiber signals. These waves are typically in the infrared range and are able to travel long distances through the fiber without losing signal strength.
Optical fibers use internal reflection to guide light along their length. This process allows for efficient transmission of light signals in technologies such as telecommunications and medical imaging.

Narinder Singh Kapany, an Indian-born physicist, is widely credited as the inventor of optical fiber. His work revolutionized telecommunications and paved the way for the high-speed, long-distance communication networks we rely on today.
The uses of optical fiber are expanding in various industries and applications due to its ability to transmit data quickly and efficiently over long distances. Industries such as telecommunications, healthcare, and transportation are increasingly relying on optical fiber for high-speed internet, medical imaging, and traffic control systems. Additionally, optical fiber is being used in sensors for monitoring environmental conditions and in security systems for data transmission. Overall, the versatility and reliability of optical fiber make it a valuable technology for a wide range of industries and applications.
Only light is used to send signals along optical fibres. That's why this type of fibre is described as "optical". Fibres designed to conduct electrical signals are referred to as "wires".
All electromagnetic radiation (light) travels at a constant speed through whatever medium it encounters. Light in a vacuum, for instance, is about 186,282 miles per second; whereas in a fiber optic cable it chugs along at only 115,000 miles per second.
Only the frequency of the communications carrier. Microwaves are electromagnetic radiation in the frequency range of 3 gigahertz to 300 gigahertz. Electromagnetic radiation above those frequencies are considered "optical" even though you can see only a small percentage of them with your eyes.

optical fibre
Light waves carry optical fiber signals. These waves are typically in the infrared range and are able to travel long distances through the fiber without losing signal strength.
Optical fibers use internal reflection to guide light along their length. This process allows for efficient transmission of light signals in technologies such as telecommunications and medical imaging.
fibre optical cable
An optical fiber (or fibre) is a glass or plastic fiber that carries light along its length. Optical fibers are widely used in fiber-optic communications, which permits transmission over longer distances and at higher bandwidths (data rates) than other forms of communications
tata tele services limited optical fibre cable
An optical fibre connection is theoretically the fastest. It is limited only by the speed of light. In practise though, the maximum speed is limited by the processing speed of the routers (or computers) at each end of the fibre. Broadly speaking, optical fibre is faster than cable or DSL.
Narinder Kapany was born in Punjab, India and educated in England. He invented optical fibre and is called "Father of Fibre Optics".
