光纤.第2-10部分:产品规范.A1类多模纤维用分规范

[中文适用范围]： IEC 60793 的本部分适用于 A1a、A1b 和 Aid 类型的光纤。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 μm 渐变折射率光纤。 A1a.1 型适用于 50/125（im 光纤），而 A1a.2 适用于 850 nm 激光优化的 50/125 urn 光纤。A1b 型适用于 62,5/125 μm 渐变折射率光纤，Aid 适用于 100/140其他应用包括但不限于以下应用：电话、分配和本地网络中传输数据、语音和/或视频服务的短距离、高比特率系统；本地建筑物内和建筑物间光纤安装，包括 LAN、PBX、视频、各种多路复用用途、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： - 一般要求，如 IEC 60793-2 中定义； - 特定要求本标准涵盖的 A1 类多模光纤的共同要求，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，在规范族规范附录中定义。 [外文原描述]： 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. 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 standard and which are given in clause 3; -particular requirements applicabe to individual fibre types or specific applications, which are defined in the normative family specification annexes. Temporarily included text of the DMD test method has been removed and modifications have been included on the A1a.1 and A1d chromatic dispersion specifications, and A1a.1 numerical aperture has been limited to one class only.
