光纤有源元件和器件 性能标准 第4部分：1 用于千兆位以太网应用的 300nm 光纤收发器

[中文适用范围]： IEC 62149-4:2022 RLV 包含官方 IEC 国际标准及其红线版本。 Redline 版本仅提供英文版本，为您提供了一种快速、简单的方法来比较官方 IEC 标准与其先前版本之间的所有更改。 IEC 62149-4:2022 定义了用于 ISO/IEC/IEEE 8802-3 千兆位以太网应用的 1 300 nm 光纤收发器模块的性能规范。本文件包含产品性能要求的定义以及一系列测试和测量，并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“一次性”运行，以证明任何产品满足性能标准要求的能力。已证明满足性能标准所有要求的产品可以声明为符合性能标准，但随后将受到质量保证/质量一致性计划的控制。第三版取消并取代了 2010 年发布的第二版。该版本构成了技术修订。该版本相对于前一版本包括以下重大技术变化： ——更新了规范性引用文件； ——删除了4.1中“短期”的条件； ——修改了表1中焊接温度的绝对极限额定值； - 表 4 中的最大光输出功率（多模光纤）从 -3.5 dBm 增加到 -3 dBm，以使值与参考文件一致； ——表7中添加注释，明确不合格产品不能通过性能测试。 [外文原描述]： IEC 62149-4:2022 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62149-4:2022 defines performance specifications for 1 300 nm fibre optic transceiver modules used for the ISO/IEC/IEEE 8802-3 Gigabit Ethernet application. 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 on a "once-off" basis to prove any product’s ability to satisfy the performance standard’s requirements. A product that has been shown to meet all the requirements of a performance standard can be declared as complying with the performance standard but will then be controlled by a quality assurance/quality conformance program. This third edition cancels and replaces the second edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - the normative references are updated; - the condition "for short periods" in 4.1 is removed; - the absolute limiting rating for soldering temperature in Table 1 is modified; - the maximal optical output power (multimode fibre) in Table 4 is increased from −3,5 dBm to −3 dBm, to align value with the referenced document; - a note is added to Table 7 to clarify that out-of-specification products are not allowed to pass the performance tests.
