标准摘要
[中文适用范围]： 本标准规定了IEC 61202-1中定义的光纤隔离器在受控环境中使用时的最低测试和测量要求及严酷度等级，以确保其符合IEC 61753-1对受控环境用隔离器的要求。要求涵盖用于受控环境的C类单模尾纤式偏振无关隔离器。 [外文原描述]： IEC 61753-061-2:2020 contains the minimum test and measurement requirements and severities which a fibre optic isolator as specified by IEC 61202-1 satisfies in order to be categorized as meeting the requirements of isolators used in controlled environments as specified in IEC 61753-1. The requirements cover single-mode pigtailed style polarization independent isolators for category C used in controlled environments. This second edition cancels and replaces the first edition published in 2012 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - addition of the detail high optical power test procedures and the condition in Annex B; - change of test conditions harmonizing with IEC 61753-1:2018; - addition of category CHD; - addition of the detailed measurements conditions in Annex C; - change of clause structure accordance with the latest ISO/IEC Directives, Part 2. The content of the corrigendum 1 (2025-05) has been included in this copy.
