IEC 62149-12:2023 IEC 62149的这一部分定义了光纤模拟无线电（RoF）系统中使用的分布式反馈激光二极管（DFB-LD）设备的性能规范。它定义了产品性能要求以及一系列具有明确定义的条件、严重程度和合格/不合格标准的测试和测量。测试旨在“一次性”运行，以证明产品满足性能要求的能力。

IEC 62149-12:2023 This part of IEC 62149 defines performance specifications for distributed feedback laser diode (DFB-LD) devices used in analogue radio over fibre (RoF) systems. It defines product performance requirements together with a series of tests and measurements with clearly defined conditions, severities, and pass/fail criteria. The tests are intended to be run on a “once-off” basis to prove a product’s ability to satisfy the performance requirements.
