    摘要： A multimode optical fiber for UV light transmission, able to be sterilized with gamma radiation, has a core including undoped synthetic silica, a cladding including fluorine doped synthetic silica, a hydrogen contcnt higher than 5 × 10 19 molecules/cm 3 and a metal coating that retards diffusion of hydrogen outwardly from the fiber, the metal being selected from aluminum, copper, zinc, tin, silver and gold. The metal coating has a high diffusion coefficient below 150° and a low diffusion coefficient at a hydrogen loading temperature above 250°C. The optical fiber may have a high-OH content of 50 to 1500 ppm and a low-OH content below 50 ppm after treatment. The optical fiber may also or alternatively have a low-OH content below 50 ppm, and preferably below 5 ppm, before treatment. A gamma radiation sterilized multimode fiber bundle may include a plurality of such optical fibers. A gamma radiation sterilized catheter may include at least one optical fiber or a fiber bundle. A process for producing the gamma radiation sterilized fibers includes manufacturing a preform having a core including undoped synthetic silica and a cladding including fluorine doped silica; drawing the preform into a fiber and annealing the fiber for reducing drawing-induced UV defects; coating the fiber with a metal coating thercby retarding migration of hydrogen outwardly from the fiber. A delivery system for transporting light including at least one optical fiber and apparatus for transporting light using the delivery system are also described.

    摘要翻译： 用于紫外线透射的多模光纤能够用γ射线消毒，其核心包括未掺杂的合成二氧化硅，包含氟掺杂的合成二氧化硅的包层，高于5×10 19分子/ cm 3的氢键 以及金属涂层，其延伸氢从纤维向外扩散，金属选自铝，铜，锌，锡，银和金。 金属涂层的扩散系数低于150℃，氢负载温度高于250℃时的扩散系数较低。光纤可以具有50〜1500ppm的高OH含量，低于50ppm的低OH含量 治疗后。 在处理之前，光纤还可以或者可选地具有低于50ppm，优选低于5ppm的低OH含量。 伽马辐射灭菌的多模光纤束可以包括多个这样的光纤。 伽马辐射灭菌的导管可以包括至少一个光纤或纤维束。 制造γ辐射灭菌纤维的方法包括制造具有包含未掺杂的合成二氧化硅的核心和包含掺氟二氧化硅的包层的预成型体; 将预制件拉制成纤维并退火纤维以减少拉伸诱导的UV缺陷; 用金属涂层涂覆纤维，从而阻止氢从纤维向外迁移。 还描述了用于传输包括至少一个光纤的光的传送系统和用于使用传送系统传输光的设备。
