标准摘要
[中文适用范围]： IEC TR 63309:2025 是一份技术报告，介绍了活性光纤的关键特性和测量方法。根据本文件的定义，活性光纤是指在纤芯中掺杂稀土离子的基于二氧化硅的光导纤维，从而实现光学增益，也称为稀土掺杂光纤。本文件的范围不包括通过其他效应（例如拉曼效应）实现光学增益的其他类型的光纤。 [外文原描述]： IEC TR 63309: 2025, which is a Technical Report, provides an introduction of active fibres describing key characteristics and measurement methods. For the purpose of this document, an active fibre is a silica-based optical fibre doped in the core with rare-earth ions to allow optical gain, named rare-earth doped fibre. Other fibres enabling optical gain by means of different effects (e.g. Raman effect) are not included in the scope of this document.
