IEC 62150-3:20 15已经发现，当侧向力施加到配合的电缆-连接器组件时，一些光收发器和插座容易受到光纤电缆引起的应力的影响，从而导致传输的光功率的变化。IEC 62150这一部分的目的是定义物理应力测试，以确保此类光学连接（电缆和插座）能够在规范范围内继续发挥作用。本标准规定了鉴定光学器件对由器件光学端口机械干扰引起的耦合功率变化的灵敏度的测试要求和程序。本标准适用于带光插座接口的有源器件。本标准描述了与具有2.5 mm或1.25 mm套圈的单模连接器一起使用的收发器的测试。第二版取消并取代了2012年出版的第一版，构成技术修订。与上一版相比，此版本包括以下重大技术变更: -除了第一版中指定的LC连接器接口收发器之外，将应用领域扩展到SC连接器接口收发器，因为这两种收发器接口在行业中都非常重要； -增加了新的附录E，涉及方法A中连接器类型的载荷值差异。 关键词:光缆引起的应力，机械扰动引起的功率变化

IEC 62150-3:2015 It has been found that some optical transceivers and receptacles are susceptible to fibre optic cable induced stress when side forces are applied to the mated cable-connector assembly, resulting in variations in the transmitted optical power. The purpose of this part of IEC 62150 is to define physical stress tests to ensure that such optical connections (cable and receptacle) can continue to function within specifications. This standard specifies the test requirements and procedures for qualifying optical devices for sensitivity to coupled power variations induced by mechanical disturbance at the optical ports of the device. This standard applies to active devices with optical receptacle interfaces. This standard describes the testing of transceivers for use with single-mode connectors having either 2,5 mm or 1,25 mm ferrules. This second edition cancels and replaces the first edition published in 2012 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- extension of application field to SC connector interface transceivers in addition to LC connector interface transceivers specified in the first edition as both transceiver interfaces are very important in the industry;
- addition of a new Annex E dealing with load value difference for connector type in Method A.
