光纤 第2-60部分：产品规范 C类单模互连光纤截面规范

[中文适用范围]： IEC 60793-2-60:2025 RLV 包含正式的 IEC 国际标准及其红线版本。红线版本仅提供英文版，便于用户快速、轻松地比较正式 IEC 标准与其前一版之间的所有变更。IEC 60793-2-60:2025 适用于表 1 中描述的 C1、C2、C3 和 C4 类光纤。这些光纤用于光学组件系统内部或之间的互连，并优化以支持密集的光学连接。虽然这些光纤可以加护套或缓冲层以制作受保护的猪尾线，但也可以不加护套使用。不过，它们可以进行颜色编码。本版取消并替代了 2008 年发布的首版，本版为技术修订版。与前一版相比，本版包括以下重大技术变更：a) 将“内部连接”替换为“互连”，并增加了“互连光纤”的定义；b) 修改了 C1 光纤的标称 MFD 限制；c) 增加了 C 类光纤的“主涂覆层直径-着色”限制，并修改了 C_80 类光纤的“主涂覆层直径-非着色”限制；d) 修改了 C1、C2 和 C3 类光纤的涂覆层剥离力限制；e) 将“光纤截止波长”替换为“电缆截止波长”，并修订了表 6 中的“备注 b”；f) 将“光纤截止波长”替换为“电缆截止波长”，并删除了表 8 中的“备注”；g) 在表 A.1 中增加了 C1_125 光纤的 200 微米涂覆层直径要求，并修改了 C1_80 光纤的涂覆层直径限制；h) 在表 A.2 和表 A.5 中增加了 C1_125 光纤的 200 微米涂覆层直径要求，并修改了涂覆层剥离力限制；i) 将“光纤截止波长”替换为“电缆截止波长”，修改了“电缆截止波长”限制，并在表 A.3 中增加了一个新的“备注”；j) 在表 A.4 中增加了 1 625 nm 的传输要求，并删除了 C1 光纤的 1 310 nm 要求；k) 修改了表 C.3 中 C3 光纤的“光纤截止波长”限制；l) 在表 D.3 中将 C4 光纤的“光纤截止波长”替换为“电缆截止波长”。 [外文原描述]： IEC 60793-2-60:2025 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 60793-2-60:2025 is applicable to optical fibre types C1, C2, C3, and C4, as described in Table 1. These fibres are used for the interconnections within or between optical components systems and are optimized to support dense optical connectivity. While the fibres can be overcoated or buffered for the purpose of making protected pigtails, they can be used without overcoating. They can, however, be colour coded. This second edition cancels and replaces the first edition published in 2008. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) replacement of "intraconnection" with "interconnection" and addition of the definition of "interconnection fibres"; b) modification of the nominal MFD limit of C1 fibres; c) addition of "Primary coating diameter-coloured" limits for class C fibres and change of "Primary coating diameter-uncoloured" limits for class C_80 fibres; d) change of coating strip force limits for class C1, class C2, and class C3 fibres; e) replacement of "Fibre cut-off wavelength" with "Cable cut-off wavelength" and revision of "Note b" in Table 6; f) replacement of "Fibre cut-off wavelength" with "Cable cut-off wavelength" and deletion of the "Note" in Table 8; g) addition of 200 μm coating diameter requirements for C1_125 fibres and change of coating diameters limits for C1_80 fibres in Table A.1; h) addition of 200 µm coating diameter requirements for C1_125 fibres and change of coating strip force limits in Table A.2 and in Table A.5; i) replacement of "Fibre cut-off wavelength" with "Cable cut-off wavelength", modification of the "Cable cut-off wavelength" limit and addition of a new "Note" in Table A.3; j) addition of a transmission requirements at 1 625 nm and deletion of 1 310 nm for C1 fibres in Table A.4; k) modification of "Fibre cut-off wavelength" limits of C3 fibres in Table C.3; l) replacement of "Fibre cut-off wavelength" with "Cable cut-off wavelength" for C4 fibres in Table D.3.
