标准摘要
[中文适用范围]： IEC 61746 的这一部分提供了校准多模光时域反射计 (OTDR) 的程序。它涵盖了 OTDR 测量误差和不确定性。激光源模态条件的测试作为可选测量包括在内。本标准不包括 OTDR 响应的校正。 [外文原描述]： IEC 61746-2:2010 provides procedures for calibrating multimode optical time domain reflectometers (OTDR). It covers OTDR measurement errors and uncertainties. The test of the laser(s) source modal condition is included as an optional measurement. This standard does not cover correction of the OTDR response. Keywords: calibrating multimode optical time domain reflectometers (OTDR)
