+AMD1:2022 CSV 光纤第2-10部分:产品规范A1类多模光纤分规范

[中文适用范围]： 本部分IEC 60793适用于光纤子类别A1-OM1、A1-OM2、A1-OM3、A1-OM4、A1-OM5和A1d。这些光纤用于或可纳入信息传输设备和光纤电缆中。 子类别A1-OM2、A1-OM3、A1-OM4和A1-OM5适用于50/125μm渐变折射率光纤的四个带宽等级。每个带宽等级定义了两个宏弯损耗性能水平，分别由"a"或"b"后缀区分。带有"a"后缀的子类别需满足传统宏弯损耗性能水平，带有"b"后缀的子类别需满足增强宏弯损耗（即更低损耗）性能水平。 子类别A1-OM5被指定用于支持在850nm至950nm附近的单波长或多波长传输系统。尽管未规范性地指定，A1-OM3和A1-OM4也包含了涵盖此波长范围的带宽信息。 子类别A1-OM1适用于62.5/125μm渐变折射率光纤，子类别A1d适用于100/140μm渐变折射率光纤。 其他应用包括但不限于以下领域：电话、分发和本地网络中承载数据、语音和/或视频服务的短距离高比特率系统；包括数据中心、局域网（LANs）、存储区域网络（SANs）、专用小交换机（PBXs）、视频、各种复用用途在内的建筑物内和建筑物间光纤安装；外部电话电缆设备使用及相关杂项用途。 对这类光纤适用三类要求： · IEC 60793-2定义的一般要求；本文档涵盖的A1类多模光纤的通用特定要求（见第5章）；适用于各光纤子类别/型号或特定应用的个别要求（见规范性附录A至D）。 表1显示了本文档使用的IEC A1多模光纤命名与IEC 60793-2-10:2017中命名的对照关系，并指向包含详细规范的规范性附录A、B和C。 [外文原描述]： IEC 60793-2-10:2019+A1:2022 is applicable to optical fibre sub-categories A1-OM1, A1-OM2, A1-OM3, A1-OM4, A1-OM5, and A1d. These fibres are used or can be incorporated in information transmission equipment and optical fibre cables. Sub-categories A1-OM2, A1-OM3, A1-OM4 and A1-OM5 apply to 50/125 µm graded index fibre in four bandwidth grades. Each of these bandwidth grades is defined for two levels of macrobend loss performance that are distinguished by "a" or "b" suffix. Those sub-categories with suffix "a" are specified to meet traditional macrobend loss performance levels. Those sub-categories with suffix "b" are specified to meet enhanced macrobend loss (i.e. lower loss) performance levels. Sub-category A1-OM5 is specified to support single wavelength or multi-wavelength transmission systems in the vicinity of 850 nm to 950 nm. Although not normatively specified, bandwidth information covering this wavelength range is also included for A1-OM3 and A1-OM4. Sub-category A1-OM1 applies to 62,5/125 µm graded index fibre and sub-category A1d applies to 100/140 µm graded index fibre. Other applications include, but are not restricted to, the following: short reach, high bit-rate systems in telephony, distribution and local networks carrying data, voice and/or video services; on-premises intra-building and inter-building fibre installations including data centres, local area networks (LANs), storage area networks (SANs), private branch exchanges (PBXs), video, various multiplexing uses, outside telephone cable plant use, and miscellaneous related uses.Three types of requirements apply to these fibres: - general requirements, as defined in IEC 60793-2; - specific requirements common to the category A1 multimode fibres covered in this document and which are given in Clause 5; - particular requirements applicable to individual fibre sub-categories and models, or specific applications, which are defined in the normative specification Annexes A to D. This seventh edition cancels and replaces the sixth edition published in 2017. This edition constitutes a technical revision. This edition includes the following significant change with respect to the previous edition: revision of the naming convention for A1 multimode fibres, which better matches with those found in ISO/IEC standards. These changes are outlined in the scope of this document along with a cross reference table for the new names. Keywords: optical fibre sub-categories A1-OM1, A1-OM2, A1-OM3, A1-OM4, A1-OM5, and A1d
