    Abstract: An improved coating (16) for optical fibers (8) and a method for applying the improved coating (16) are described. The present invention is a dimensionally precise and uniform coating (16) with low-porosity. The improved coating (16) is applied via sputtering within a vacuum chamber (2). Environmental conditions are monitored within a cylindrical magnetron (4) during sputtering. Sputtering is adjusted or temporarily ceased when environmental conditions approach a damage threshold. Sputtered particles (38) within a plasma cloud (46) are dimensionally similar and adhere to an optical fiber (8) in a volume efficient arrangement forming a more precise, denser, and more adherent coating (16). Embodiments of the present invention provide improved pull strength by compressively constraining the optical fiber (8) within the coating (16) and by closing microcracks.
