Now that we know how fiber-optic systems work and why they are useful -- how do they make them? Optical fibers are made of extremely pure optical glass.
Students often ask how fiber is made. It's certainly not obvious how something only 1/8 of a mm - inches - in diameter can be made with such precison.
Surely the word fiber is not new for you, is it? Here is a fiber page that you could visit right now, just in case you don't know what fibers are. Many polymers can.
An optical fiber is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair. Optical fibers are.
Background. An optical fiber is a single, hair-fine filament drawn from molten silica glass. These fibers are replacing metal wire as the transmission medium in .

Optical fiber is an extremely thin glass wire that has an external diameter of micron (1micron = 1 millimeter divided into parts). To understand how.
Today, it has replaced metal wires in high speed communication. In a fiber optic communications system, cables made of optical fibers connect.
Generally fibers are made by drawing a thin strand of glass from a specifically designed glass rod (called a preform). The fiber is coated with a protective acrylate.
