Facts about Fiber Optic Cables
1.Outer insulating jacket is made of Teflon or PVC.
2.Kevler fiber helps to strengthen the cable and prevent breakage.
3.A plastic coating is used to cushion the fiber canter.
4. Center ( core) is made of glass or plastic fiber.
Optical fiber consists of thin glass fibers than can information at frequencies in the visible light spectrums and beyond. The typical optical fibe consists of a very narrow strand of glass called the core around the core there is a concentric layer of glass called the cladding. Coating the cladding is a protective coasting consisting of plastic it is called jacket.
