Optical Fiber is a type of cable that is used for transmitting data at high speeds over long distances. It is most commonly used in high-speed networks such as the internet and communications systems. Optical Fiber consists of a core and cladding which are both made of glass, with the core having a slightly higher refractive index than the cladding, which causes the light to be reflected inside the cable. The core carries the light while the cladding prevents it from escaping.
Optical Fiber is superior to copper wire in terms of speed, affordability, and immunity to electromagnetic interference. Not only does it carry much more data than copper wire, but it is also more cost-effective. This is because power is not lost due to attenuation, as well as the fact that it requires fewer repeaters due to its superior signal integrity. In addition, optical fibers are immune to electromagnetic interference, which allows for higher speeds with less interference on networks.
The most common types of optical fiber available are multi-mode fiber and single-mode fiber. Multi-mode fiber has a larger core diameter than single-mode fiber and allows for multiple modes of light to travel through the core. Single-mode fiber is much more efficient than multi-mode fiber and has a much lower attenuation rate, allowing it to carry data further distances.
Optical Fiber is widely used in communications systems and computer networks, as well as in medical imaging, factories, and for home audio-visual systems. Its speed, affordability, and immunity to interference makes it the ideal choice for high-speed data transmission.
