Fiber optics refers to the technology and method of transmitting data as light pulses along a glass or plastic strand or fiber. Fiber optic cables are used for long-distance and high-performance data networking. They are capable of transmitting data over longer distances and at higher bandwidths (data rates) than electrical cables, making them a critical component in modern telecommunications, internet, and computer networking.

Fiber Optics or Optical Fiber is a technology that transmits data as a light pulse along a glass or plastic fiber. An Optical Fiber is a cylindrical fiber of glass that is hair-thin in size or any transparent dielectric medium. The fiber which is used for optical communication is waveguides made of transparent dielectrics. In this article, we will discuss Optical Fiber/Fiber Optics in detail.

Fibre optics technology uses light pulses through glass or plastic fibres to transmit data at fast speeds and over long distances. Fibre optics, with its high bandwidth, low electromagnetic interference, and resilience, is critical for modern telecommunications, internet, medical, and military applications. Despite greater costs and installation issues, its advantages make it the best option for effective data communication.

Fiber Optics has the work of transmission of light particles, or photons. Fiber optics transmit data as light through thin sheets of glass or plastic. Each fiber consists of a core, where the light travels through it, and a surrounding cladding that reflects the light back into the core part. Data is converted into light using a laser or LED, and these light pulses travel through the core, bouncing off the cladding to stay contained in it. At the receiving end, a photodetector converts the light back into the electrical signals. This technology allows for fast, high-capacity data transmission with minimal signal loss, immunity to electromagnetic interference, and therefore the security is enhanced. Fiber optics are generally used for high-speed internet, telecommunications, medical devices, and many more industrial applications.
