BS EN 4869-103标准是航空航天领域中扩展光束端子的技术规范之一。扩展光束端子是一种光纤连接器,其特点是在连接时不需要物理接触,而是通过扩展光束的方式进行信号传输。这种连接方式具有高速传输、低损耗、抗干扰等优点,因此在航空航天领域中得到了广泛应用。
BS EN 4869-103标准规定了多模男性端子尺寸为12的扩展光束端子的技术要求。标准规定了端子的尺寸、材料、性能、测试方法等方面的要求,以确保其在航空航天领域中的可靠性和稳定性。具体要求如下:
1. 端子尺寸:端子的外径为12mm,长度为28mm。
2. 端子材料:端子的外壳材料为不锈钢,内部光学元件材料为陶瓷。
3. 端子性能:端子的插拔次数应不少于500次,连接时的插损应小于0.5dB,回波损耗应小于-20dB。
4. 端子测试:端子应经过光学性能测试、机械性能测试、环境适应性测试等多项测试,以确保其符合标准要求。
BS EN 4869-103标准的实施可以提高航空航天领域中扩展光束端子的质量和可靠性,保证其在复杂的环境下稳定工作。同时,该标准的实施也有助于推动航空航天领域中光纤连接技术的发展和应用。
