摘要： Methods for modifying preform core ovality during and subsequent to the formation of an optical fiber preform. After MCVD deposition forms the core rod, but prior to overcladding of the core rod, the code rod may be etched to change its ovality. In order to etch the core rod, the core rod may be mounted to lathe, rotated by at least two rotors, and subjected to a heat source. Additionally, one of the at least two rotors may be phase-shifted from another one of the at least two rotors after the core rod is mounted on the lathe.

摘要： Embodiments of the invention include an optical fiber preform assembly and a method for making optical fiber using the preform assembly. The assembly includes a preform core rod, at least one overclad tube formed around the preform core rod, a handle attached to one end of the overclad tube, and a refractory material positioned in the overclad tube between the preform core rod and the handle. The refractory material reduces if not prevents movement of the preform core rod into the handle during the fiber draw process. Preferably, the refractory material is made of, e.g., magnesium oxide and/or aluminum oxide, and has a melting point, e.g., greater than approximately 2000 degrees Celsius. Embodiments of the invention also include a method for making optical fiber using this preform assembly.

摘要： Embodiments of the invention include a system and method for color-coating an optical fiber. The system includes a flow controller that controllably delivers and mixes color concentrate from one or more color concentrate reservoirs with a coating material, which colored coating material is fed to a coating die through which optical fiber passes. The color concentrate reservoirs are more compact and can be made portable along with the flow controller. Thus, the entire color coating system can travel to any appropriate location in the fiber manufacturing facility, e.g., at any one of a number of draw towers. Such portability allows many different colors to be used at the same draw tower much more easily than conventional arrangements, which typically only have one color line per draw tower. The method includes providing an optical fiber, controllably delivering color concentrate with a coating material to a coating die, coating the optical fiber with the coating die, and curing the coated fiber.
