Ultraviolet reflectivity of metallic aluminum is the highest versus other metallic material, so metallic aluminum is the optimum material for fabrication hollow-core fiber.

相对于其他的金属材料而言，金属铝的紫外反射率最高，因此金属铝最适合用做制备空芯光纤的金属膜层材料。

The covering material that encases the core of an optical fiber. the cladding material usually has a lower index of refraction than the core material and may be either glass or plastic.

一种包装光纤芯的保护材料。保护材料的折射率通常比光纤芯的折射率低，它一般是玻璃或塑料。

The core material (110) can be formed at low cost in following mode: penetrating glass wool provided with the glass fiber by using a needle to tangle and gather the glass fiber.

以以下方式可以以低成本形成芯材料（110）： 通过使用针穿透具有玻璃纤维的玻璃绒而缠结和聚集玻璃纤维。
