OTDR 1

1 光时域反射仪简介

光时域反射仪可让您表征光纤跨段，它通常由光纤区段通过接头和连接器连

接而成。光时域反射仪 (OTDR) 可查看光纤的内部状况且能计算光纤长度、

衰减、断裂、总回损及接头损耗、连接器损耗和总损耗。

主要特色

本 OTDR：

 提供出色的动态范围和很短的盲区。

 可进行具有低噪声电平的快速取样，以实现精确的低损耗接头定位。

 获取 OTDR 曲线（由多达 256000 个点组成），所提供的采样分辨率可

精确到 4 cm。

 包括光源和可选购的可视故障定位仪。。

曲线取样模式

OTDR 应用程序提供以下曲线取样模式：

 “自动”：自动计算光纤长度、设置取样参数、获取曲线并显示事件表和

采集的曲线。

 “高级”：提供执行完整 OTDR 测试和测量需要的所有工具，并允许您控

制所有测试参数。

 “模板”（可选）：测试光纤并和之前获取且分析过的参考曲线比较结

果。测试大量光纤时，这可帮您节省时间。参考曲线文件也会自动复制

到新的取样。

 故障寻找器：迅速定位光纤末端并显示被测光纤长度。这可让您执行快

速测试而无需设置所有取样参数。

可选软件包

可选软件包与应用程序一起提供。使用此软件包，可找到宏弯，查看相关信

息。利用此软件包可以访问 “线性视图”（从左到右按顺序显示事件）。

注意：可选软件包可在 FTB-200 v2 设备上使用，但不能用于 FTB-200 设备上。

数据后期处理

您可在计算机上安装 OTDR Viewer （产品随附的 CD 中提供）查看和分析曲

线，而不必使用 FTB-200 v2 紧凑型模块化平台以及 OTDR。您还可以访问更

多功能，例如：

 定制打印输出

 批量打印

 将曲线转换为 Telcordia 或 ASCII 等多种格式。

双向分析程序

您可使用双向分析应用程序提高损耗测量的准确度。该实用程序使用从光纤

跨段两端进行的 OTDR 取样（仅限单模曲线），计算各事件损耗结果的平均

值。
