单模光纤和光缆的线性与确定性属性的定义和测试方法
ITU-T G.650.1建议书包含了单模光纤和光缆的线性、确定性参数的定义。它还包含表征这些参数的参考测试方法和替代测试方法。这些测试方法主要适用于单模光纤和光缆的线性、确定性属性的出厂测量。某些测试方法也可以用于表征离散的光器件。本建议书的历史沿革如下:1993年:从诸如ITU-T G.652建议书等单模光纤建议书中移除定义和测试方法,并用于创建ITU-T G.650建议书的初始版本。1997年:ITU-T G.650建议书第二版增加了极化模色散的定义和测试方法及附录一、二、三。还增加了改进的截止波长测定(5.3.1.3.4节)。2000年:第三版确立了极化模色散的参考和替代测试方法,修改了纤心同心度误差的定义和测试方法(第3.4和5.2节),并增加了第5.1.4节和附录四、五和六。2002年:为了便于维护,ITU-T G.650建议书被分成更小的建议书。ITU-T G.650.2建议书包含了单模光纤和光缆的统计和非线性属性的定义和测试方法。2004年:ITU-T G.650.1建议书第二版增加了第三种备选测试方法“衰减光谱建模”(第5.4.4节)和新的附录三“矩阵模型示例”。这种材料已从单模光纤建议书移至此ITU-T G.650.1建议书中。此外,还增加了多色色散拟合程序(附件A)。2010年:ITU-T G.650.1建议书第三版增加了“宏弯损耗测试方法”测试方法(第5.6节)。已从第5.3节中删除了跳线截止波长。在截止波长测试方法(第5.3.1.3.2节)中增加了补充说明。纠正了等式5-1。在证明测试方法(第5.7节)中增加了详细的说明。附录二已更新。2018年:ITU-T G.650.1建议书第四版增加了附录四(源自2012年出版的修正1),以提供相干多径干扰(MPI)的测量程序。用于多色色散测量的干涉仪技术已从第6.5节中删除,并移至附录五。改进了ITU-T G.657光纤在MFD、截止波长和光谱衰减测试中的测量细节描述。修改了光缆截止波长测量的RTM和ATM。在I.3节中增加了插值法的例子。等式61已纠正。2020年:ITU-T G.650.1建议书第五版修订了第三种替代测试方法“衰减光谱建模”(第6.4.4节),以涵盖少数预测波长对更窄波长范围建模的适用性。在附录三“矩阵模型示例”中,现有的ITU-T G.652光纤示例矩阵被一个使用四种预测波长的新矩阵取代,并为使用三种预测波长的ITU-T G.654.E光纤增加了一个新矩阵。解释了建模误差随预测波长数量变化的波长依赖性。2023年:ITU-T G.650.1建议书第六版修订了参考测试方法“远场扫描”(第6.1.1节)。引入了分辨率系数K,表示探测器的有效区域与到光纤端的距离之间的关系。最小动态范围已被概括。修改了对远场扫描用探测器的描述。此外,在第一种替代测试方法“可变孔径技术”(第6.1.2节)中,除ITU-TG.653光纤外,ITU-TG.655和G.656光纤的最大数值孔径也建议为0.4。
