标准摘要
[中文适用范围]： IEC 61753 的这一部分包含分支设备为满足 IEC 标准而应满足的最低初始化测试和测量要求以及严重性。这些要求涵盖在 IEC U 类环境中使用的平衡非连接单模 1×N 和 2×N 非波长选择分支设备（N 是输出端口的数量）。不平衡分支器件的规格仅限于1×2和2×2器件，因为它们是最常用的。 [外文原描述]： Specifies the minimum initialisation test and measurement requirements and severities for a branching device. The requirements cover balanced non-connectorised single-mode 1xN and 2xN non-wavelength-selective branching devices (N is the number of output ports).
