IEC 61281-1:20 17是光纤通信子系统（FOCSs）的通用规范。本文定义的参数形成所有光纤子系统共有的可指定的最小规格集合。根据特定应用和技术，可以使用附加参数。这些附加参数将酌情在相关文件中规定。使用测试程序之一测量每个指定参数。设计指南中给出了这些参数在系统设计中的使用。这第二版取消并取代了1999年出版的第一版。本版构成技术修订版。与上一版相比，本版包括以下重大技术变化:增加了新的定义。 关键词:光纤通信子系统(FOCSs)

IEC 61281-1:2017 is a generic specification for fibre optic communication subsystems (FOCSs). The parameters defined herein form a specifiable minimum set of specifications that are common to all fibre optic subsystems. Additional parameters can be used depending on the particular application and technology. Those additional parameters will be specified in the relevant documents, as appropriate. Each specified parameter is measured using one of the test procedures. The use of these parameters for system design is given in design guides. This second edition cancels and replaces the first edition published in 1999. This edition constitutes a technical revision. This edition includes the following significant technical change with respect to the previous edition: addition of new definitions.
