IEC 61300-2-2:2009规定了一项试验，以评估光纤连接器或其他互连装置在正常使用条件下连续多次啮合和分离对光学性能和部件机械性能退化的影响。与前一版本相比的具体技术变化包括插头插座配置的配合耐久性测试、新的测量条件和新的严重程度。

IEC 61300-2-2:2009 specifies a test to evaluate the effects of a number of successive cycles of engagement and separation of fibre optic connectors or other interconnecting devices on optical performance and mechanical degradation of the component under normal conditions of use. Specific technical changes from the previous edition include a mating durability test for a plug-socket configuration, a new measurement condition and a new severity level.
