光纤功率计的校准

[中文适用范围]： 本文件适用于测量光纤通信行业典型源发出的辐射功率的仪器。这些光源包括激光二极管、发光二极管 (LED) 和光纤型光源。发散辐射和准直辐射均被涵盖。本文件定义了由校准实验室或功率计制造商执行的功率计校准。 [外文原描述]： IEC 61315:2019 is applicable to instruments measuring radiant power emitted from sources that are typical for the fibre-optic communications industry. These sources include laser diodes, light emitting diodes (LEDs) and fibre-type sources. Both divergent and collimated radiations are covered. This document defines the calibration of power meters to be performed by calibration laboratories or by power meter manufacturers. This third edition cancels and replaces the second edition published in 2005. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) update of terms and definitions; b) update of 5.1, including Table 1 (new type of source); c) update of Annex A; d) addition of Annex B on dB conversion.
