  • Page 11: Basic Information Of Otdr

    OCC-CWDM-301-18 3. Basic Information of OTDR 3.1 Principle of OTDR OTDR (Optical Time Domain Reflectometer) is a measurement instrument for identifying optic fiber transmission features. The instrument is mainly used to measure attenuation of a whole optic fiber chain and provide attenuation details relating to length, namely detect, locate and measure any event in optic fiber chain (events refer to faults caused by welding, connectors, and bending whose transmission change can be measured).
  • Page 12 OCC-CWDM-301-18 3.2.1.1 Reflection Events When some pulse energy is scattered, reflection events happen. When reflection event occurs, peak shows on trace, as shown in Figure 3-1. Figure 3-1. Reflection Event 3.2.1.2 Non-Reflection Events Non-reflection events happen at certain points where there is some optic loss but no light scattering. When non- reflection event occurs, a power decline shows on trace, as in Figure 3-2.
