IEC 62148-1:20 17（E）旨在确保光纤有源组件和不同制造商提供的设备之间物理接口的互换性，但不保证此类设备之间的操作。第二版取消并取代了2002年出版的第一版，构成了技术修订。该版本相对于上一版本包括以下重大技术变化:在条款5中增加了自由空间光耦合接口。 关键词:光纤组件之间的物理接口

IEC 62148-1:2017(E) aims to assure interchangeability in physical interfaces between fibre optic active components and devices supplied by different manufacturers, but it does not guarantee operation between such devices. This second edition cancels and replaces the first edition, published in 2002, and constitutes a technical revision. This edition includes the following significant technical change with respect to the previous edition: addition of a free space optical coupling interface in Clause 5.
