摘要： A method of processing an optical fiber includes drawing the optical fiber from a heated glass source, reheating the optical fiber, and cooling the optical fiber under vacuum at a cooling rate less than the cooling rate of the optical fiber in air at 25°C and 1 atm. Cooling the optical fiber under vacuum is conducted after reheating the optical fiber. Cooling the optical fiber under vacuum reduces the rate of heat transfer from the optical fiber, which may enable further relaxation of the glass and reduction in the fictive temperature of the optical fiber. A system for processing an optical fiber includes a furnace containing a fiber preform, a first positioner, a reheating device, and a treatment device downstream of the reheating device, the treatment device operable to cool the optical fiber under vacuum to reduce the rate of heat transfer from the optical fiber.

摘要： A method for forming an optical fiber preform is provided. The method includes inserting a glass core cane (511) into a glass sleeve (32) such that the glass sleeve (32) surrounds a portion of the glass core cane (511) and such that there is a gap between the glass sleeve and the portion of the glass core cane surrounded by the glass sleeve. The method further includes depositing silica soot (36) onto at least a portion of the glass core cane (511) and at least a portion of the glass sleeve (32) to form a silica soot preform (28), and flowing gas through the gap during processing of the silica soot preform, e.g. sintering. The processing time can be reduced. Alternatively the glass core can can be attached to a handle comprising a hollow interior portion connected to the exterior of the handle by at least one opening in the handle wall. Soot is deposited onto a portion of the core cane and a portion of the handle and gas is flowed through the opening during processsing of the silica soot preform.
