标准摘要
[中文适用范围]: IEC 60793的本部分适用于光纤类型A1a@、A1b@和A1d。这些光纤被使用或可以并入信息传输设备和光缆中。 A1a 型光纤是 50/125 mm 渐变折射率光纤。 A1a.1 型适用于 50/125 mm 光纤@,而 A1a.2 和 A1a.3 适用于 850 nm 激光优化的 50/125 mm 光纤的两个带宽等级。 A1b 型适用于 62@5/125 mm 渐变折射率光纤,A1d 型适用于 100/140 mm 渐变折射率光纤。其他应用包括但不限于以下内容:短距离、电话中的高比特率系统、分配和承载数据、语音和/或视频服务的本地网络;本地建筑物内和建筑物间光纤安装,包括数据中心@局域网@存储区域网络@PBX@视频@各种复用用途@外部电话电缆设备用途@以及其他相关用途。这些光纤适用三种类型的要求: IEC 60793-2 中定义的“C 一般要求”; ?C 本标准涵盖的 A1 类多模光纤的共同具体要求,并在第 3 章中给出; ?适用于个别光纤类型或特定应用的特殊要求@,这些要求在标准系列规范附件中定义。 [外文原描述]: IEC 60793-2-10:2011 is applicable to optical fibre types A1a, A1b, and A1d. These fibres are used or can be incorporated in information transmission equipment and optical fibre cables. 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, LANs, Storage Area Networks, PBXs, video, various multiplexing uses, outside telephone cable plant use, and miscellaneous related uses. The major changes with respect to the previous edition are: - addition of type A1a.3 fibre; - reduction of core diameter tolerance from 3,0 to 2,5 mum for A1a fibres.
