摘要: A method of manufacturing an optical fiber includes providing a preform in a furnace, and drawing a plurality of optical fibers from the preform at a plurality of different draw tensions. A bandwidth characteristic of each of the optical fiber is drawn at the different draw tensions is measured. A draw tension setpoint is selected based on the measured bandwidth characteristic of each optical fiber and the draw tension is adjusted to the selected draw tension setpoint. The method further includes drawing from the preform a tuned optical fiber at the selected draw tension setpoint which provides peak bandwidth.
