标准摘要
[中文适用范围]： IEC 61755 的这一部分定义了一组应保持的规定条件，以满足非角度抛光参考连接的要求。规定的条件包括光学接口的尺寸限制和光纤要求，以满足用于衰减测量的参考连接（插头和适配器）的特定要求。本标准定义了两种不同等级的参考连接。每个等级的使用取决于应用和目标衰减测量不确定度。该模型在指定的受限模场直径 (MFD) 范围内使用光强度的高斯分布。本标准旨在用于装运和验收检查。参考连接器插头适用于 IEC 60793-2-50 中规定的 B1.1@ B1.3 和 B6 光纤。在光纤分类困难的地方，例如光缆设备的建设和维护，不建议使用参考连接器插头。 [外文原描述]： IEC 61755-2-4:2015 defines a set of prescribed conditions that should be maintained in order to satisfy the requirements of non-angled polished reference connections. The prescribed conditions include dimensional limits and optical fibre requirements of the optical interface to meet specific requirements for reference connection (plugs and adaptors) used for attenuation measurements. Two different grades for reference connections are defined in this standard. The use of each of these grades depends on the application and on the targeted attenuation measurement uncertainty. The model uses a Gaussian distribution of light intensity over the specified restricted mode field diameter (MFD) range. This standard is intended to be used for shipping and acceptance inspections. The reference connector plug is specified for B1.1, B1.3 and B6 fibres as specified in IEC 60793-2-50. The use of the reference connector plug would not be recommended where classification of fibre is difficult, for example construction and maintenance of cable plant. Keywords: non-angled polished reference connections, plugs and adaptors, attenuation measurements
