IEC 62149-3:20 23涵盖了用于40 Gbit/s光纤传输系统的与激光二极管单片集成的电吸收(EA)型光调制器的性能规范。本文件包含产品性能要求的定义以及一系列测试和测量，其中提供了明确定义的条件、严重性和通过/失败标准。这些测试旨在作为初始设计验证运行，以证明任何产品满足本文件要求的能力。本文档适用于开关键控调制格式。已被证明符合性能标准所有要求的产品可以被宣布为符合性能标准，但随后将由质量保证计划进行控制。这第四版取消并取代了2020年出版的第三版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更: a)表6中根据纤维类型的纤维拉伸试验的拉力规格； b)表4和表5中无扭结辐射功率的符号变化； c)替换表7中未定义的符号； d)增加IEC 62149-1作为规范性参考。

IEC 62149-3: 2023 covers the performance specification for electroabsorption (EA) type optical modulators monolithically integrated with laser diodes for 40 Gbit/s fibre optic transmission systems. This document contains definitions for product performance requirements as well as a series of tests and measurements, for which clearly defined conditions, severities and pass/fail criteria are provided. The tests are intended to be run as an initial design verification to prove any product's ability to satisfy this document's requirements. This document is applicable for on-off keying modulation formats. A product that has been shown to meet all the requirements of a performance standard can be declared as compliant with the performance standard but will then be controlled by a quality assurance program. This fourth edition cancels and replaces the third edition published in 2020. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) specification of pull force for fibre pull test in Table 6 according to fibre type;
b) change of symbol for kink free radiant power in Table 4 and Table 5;
c) replacement of undefined symbols in Table 7;
d) addition of IEC 62149-1 as a normative reference.
