Preforms and optical fibers coated in alumina and/or silica |
摘要 |
The invention relates to an optical fiber preform comprising an optical core, optical cladding, and an outer sheath, in which the outer sheath includes a peripheral zone containing 20% to 100% by weight alumina and 80% to 0% by weight silica. Such a preform makes it possible to obtain optical fibers having improved mechanical strength and improved impermeability to hydrogen.
