标准摘要
[中文适用范围]： 本部分 IEC 61746 提供了校准单模光时域反射仪（OTDR）的程序。它仅涵盖 OTDR 测量误差和不确定度。本标准不涵盖 OTDR 响应的校正。 [外文原描述]： IEC 61746-1: 2009 provides procedures for calibrating single-mode optical time domain reflectometers (OTDR). It only covers OTDR measurement errors and uncertainties. This standard does not cover correction of the OTDR response. This first edition of IEC 61746-1 cancels and replaces the second edition of IEC 61746, published in 2005. It constitutes a technical revision. The main technical changes are the adaptation of Clause 4, the suppression of Clause 10, the improvement and the addition of some definitions, the change of some calculations and the change of graphical symbology to IEC/TR 61930. Keywords: calibrating single-mode optical time domain reflectometers (OTDR)
