光纤连接器是光纤通信系统中不可或缺的组成部分，用于连接光纤互连设备和无源元件。SC-RJ连接器是一种常用的光纤连接器，具有小型化、易于安装和维护等优点。为了保护SC-RJ连接器，防止其受到机械损伤和污染，IEC 61754-24-11:2009标准规定了基于IEC 61076-3-117的SC-RJ连接器带保护外壳的光纤连接器接口。

该标准规定了连接器的尺寸、机械性能、光学性能和环境要求。连接器的尺寸应符合IEC 61755-3-31标准中的要求。连接器的机械性能应符合IEC 61754-7标准中的要求，包括插拔力、耐久性、振动和冲击等。连接器的光学性能应符合IEC 61755-3-31标准中的要求，包括插入损耗、回波损耗和偏振相关性等。连接器的环境要求应符合IEC 61753-1标准中的要求，包括温度、湿度、盐雾和紫外线等。

该标准还规定了连接器的标记和包装要求。连接器应标记有制造商、型号、序列号和生产日期等信息。连接器应采用适当的包装材料进行包装，以保护连接器免受机械损伤和污染。

IEC 61754-24-11:2009标准的发布，为光纤连接器的应用提供了更加严格的规范和标准，有助于提高光纤通信系统的可靠性和稳定性。
