2、工作原理
OTDR类似一个光雷达。它先对光纤发出一个测试激光脉冲,然后观察 从光纤上各点返回(包括瑞利散射和菲涅尔反射)的激光的功率大小情况 ,这个过程重复的进行,然后将这些结果根据需要进行平均,并以轨迹图 的形式显示出来,这个轨迹图就描述了整段光纤的情况。

菲菲涅涅尔尔反反射射
菲尼尔反射就是我们平常所理解的光反射,是指光在从一种介质 (光纤)传到另一种介质(空气)中时,被沿原介质(光纤)以入射时 相同的角度反射回来。需要注意的是菲涅尔反射是离散的,由光纤上个 别的点位置产生。而反射回来的光强度可达到入射光强度的4%。
无论光信号自光纤进入空气还是自空气 进入光纤,反射光强度比例是相同的。

OTDR原理及使用详解

OTDR原理及使用详解

OTDR原理及使用详解为什么要使用OTDROTDR工作原理OTDR定义定义OTDR的英文全称是Optical Time Domain Reflectometer,中文意思为光时域反射仪工作原理OTDR在精准时钟电路的控制之下,按照设定的参数向光口发射光脉冲信号,之后OTDR不断的按照一定的时间间隔从光口接收从光纤中反射回的光信号,分别按照瑞利背向散射(测试光钎的损耗)和菲涅尔反射(测试光钎的反射)的原理对光纤进行相应的测试。

Rayleigh 背向散射(瑞利散射)原因源于光纤内部微小粒子或不均匀结构反射和吸收,当光照射到杂质上时,一些颗粒将光重定向到不同的方向,同时产生了信号衰减和背向散射。

规律其损耗的大小与波长的4次方成反比,即随着波长的增加,损耗迅速下降。

光纤中某一点的后向回波可以反映出光纤中光功率的分布情况,椐此可以测试出光纤的损耗。

损耗:Rayleigh Backscatter(瑞利背向散射)=5Log(P0×W×S)-10ax(loge)式中:P0:发射的光功率(瓦)W:传输的脉冲宽度(秒)S:光纤的反射系数(瓦/焦耳)a:光纤的衰减系数(奈踣/米)1奈踣=8.686dBx:光纤距离Fresnel 反射(非涅尔反射)原因当光到达折射率突变的位置(比如从玻璃到空气)时,很大一部分光被反射回去,产生Fresnel 反射,它可能比Rayleigh 背向散射强上千倍。

Fresnel 反射可通过OTDR 轨迹的尖峰来识别。

产生位置这样的反射例子有连接器、机械接头、光纤、光纤断裂或打开的连接器。

用途可检测链路沿线的物理事件。

OTDR 的结构OTDR测试过程第一步:清理光纤接口端面(法兰口)第二步:用光功率计测试链路是否有光(有强光会损坏OTDR)第三步:了解待测链路的状态,设置OTDR相应的参数第四步:OTDR测试及结果分析,保存距离测量原理如果折射率“n”设置不正确,所测出的距离也将是错误的!!损耗测量原理OTDR 产生返回光强度(背向散射加上反射)与光纤长度相关的光纤曲线熔接损耗是一种由于信号电平在接头点突然下降而造成的点损耗熔接时如果接点含有空气隙,就会产生具有反射的点损耗。

Oracle FieldService/Laptop and Oracle Field Service/Palm™ Devices let you accessyour field service information while on the road. You can workindependently from the corporate network and then synchronize yourchanges back to the central database, either over a phone line, aLAN/WAN, or by wireless connection.The Palm DeviceOracle Field Service/Palm™ Devices provides all the data you need onyour hand-held devices running for UNIX and for Windows to performservice tasks while away from the office. To be effective, the data residingon the Palm needs to be regularly updated with Oracle Field Service, anddata that you entered into your Palm Device needs to be transferred toOracle Field Service. This process of transferring data to and from yourPalm Device is known as synchronization.The Mobile Device GatewayThe CRM Gateway for Mobile Devices consists of a mobile client and acentral application. It provides data transport between the Oracle CRMenterprise database and the Oracle mobile client database. The CRMGateway for Mobile Devices sends correct data to each servicerepresentative. It only transports changed, new, or missing data because itknows what data resides on each device. The CRM Gateway for MobileDevices also acts as the communication server. It decides based uponpriority if information needs to be sent wirelessly or if it can wait untilmanual synchronization. This is done to save money, because wireless communication is very expensive.Palm Device Application FlowThe figure shows the relationship between the different screens in the Oracle Field Service Palm application.I When new mail messages arrive, the mail notification icon is up. It isdown when all the mail is read.
