IXC (IntereXchange Carrier, or IEC)

preform cylinder is reheated to a temperature of 2,500 degrees in a drawing tower. The resulting gob of molten glass is carefully drawn by gravity, in a process known as broomsticking, into a fiber as long as 20

kilometers. As the fibers cool, an acrylate coating is applied to protect the raw glass from physical damage.

As is the case with all of these techniques, OVD takes place in a vacuum environment, as it is the exposure to oxygen that makes glass so brittle. Outside vapor deposition (IVD) is a similar process, with the soot deposited on the outside of a rotating ceramic bait rod that is slipped out of the glass cylinder prior to the formation of the preform cylinder. See also cladding, core, dopant, graded-index fiber, IVD, sintering, and step-index fiber.
