本SAE航空航天标准（AS）定义了可用于安装和维修航空航天应用中的光纤互连的光纤熔接器。根据是否存在易燃蒸汽或危险大气的风险，定义了两种不同的应用环境。适用于易燃或危险环境的设备可能超出工厂、仓库或其他相对安全环境的规定。为了解决这些不同的应用环境，将在适用的详细规范中规定两种类型的熔接器:I型。用于危险环境，特别是潜在易燃或易爆环境。 第二类。对于确定不存在易燃或易爆蒸汽风险的环境。

This SAE Aerospace Standard (AS) defines fiber optic fusion splicers acceptable for the installation and repair of fiber optic interconnects in aerospace applications. Two different application environments are defined, depending on whether there is risk of flammable vapor or hazardous atmosphere being present. Equipment suited to flammable or hazardous environments may be over specified for factory, depot, or other relatively safe environments. To address these different application environments, two types of fusion splicer will be specified in applicable detail specifications: Type I. For hazardous environments specifically including potentially flammable or explosive atmospheres. Type II. For environments in which it is established that there is no risk of flammable or explosive vapors being present.
