Abstract: The invention concerns a method and apparatus for producing a carbon coated optical fiber. An optical fiber is drawn through a reactor tube. Reactant gas is flowed into the tube and onto the fiber where it reacts to form a carbon coating on the fiber. The reactant gas and reaction products are flowed in the direction of movement of the fiber and out of an end of the tube and into a receiving chamber having a diameter larger than that of the reaction tube. The reactant gas continues to react as it flows through the tube and after it exits the tube. At least some of the reaction product deposit on the surface of the receiving chamber where it has no adverse effect on the draw process.

Abstract: Method for manufacturing optical fiber comprises the steps of laying down co re and cladding materials to form a soot blank, the soot blank including a glas s modifier, loading the unconsolidated soot blank into a draw tower, providing a hot zone to heat a portion of the blank to a temperature sufficient to sinte r the soot into molten glass, and directly drawing the molten glass into eithe r a consolidated, drawn preform rod (cane) or into an optical fiber.

Abstract: Bend resistant multimode optical fibers are disclosed herein. Multimode optical fibers disclosed herein comprise a core region having a radius greater than 30 microns and a cladding region surrounding and directly adjacent to the core region, the cladding region comprising a depressed-index annular portion comprising a depressed relative refractive index. The fiber has a total outer diameter of less than 120 microns, and exhibits an overfilled bandwidth at 850 nm greater than 500 MHz-km.
