core and that's the bit the light travels through. The thin core is surrounded by cladding roughly ten times bigger in diameter, a plastic outer coating (about twice the diameter of the cladding some strengthening fibers made of a tough material such as Kevlar, with a protective outer jacket on the outside. (More technically, the cladding has a lower refractive index.) Types of fiber-optic cables Optical fibers carry light signals down them in what are called modes. If you picture the Internet (and the World Wide Web that rides on it) as a global spider's web, the strands holding it together are fiber-optic cables; according to some estimates, fiber cables cover over 99 percent of the Internet's total mileage, and carry over. 1970: Donald Keck and colleagues at Corning found ways to send signals much further (with less loss) prompting the development of the first low-loss optical fibers. Last updated: June 14, 2018. Fiber-optic cables are inexpensive, thin, lightweight, high-capacity, robust against attack, and extremely secure, so they offer perfect ways to connect military bases and other installations, such as missile launch sites and radar tracking stations. En forutsetning for at man skal kunne stole på slike tester er at de er utført av personer som selv ikke har interesser innenfor bransjen. Then you'd fire the laser down the fiber-optic cable.
