While testing, press this key to stop measurement Enter Under GUI, press this key to confirm the current operation Together with [Shift/ ], can browse the event list downwards ▲ ▼ Move menu bar in menu operation Highlight the icon to be operated Adjust parameter in parameter configuration Together with [Shi ...

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 cau ...

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 i ...

OCC-CWDM-301-18 3.3 Measurement Application of OTDR OTDR displays power relating to distance of returning signals. This information can be used to identify the main properties of an optic fiber chain. 3.3.1 Measurement Contents of OTDR • Event location (distance), end or rupture of optic fiber chain • Attenuation coefficient of fiber • Loss of a single event (for example, one optic tie-in), or total loss ...

OCC-CWDM-301-18 3.4.1 Trace Display of OTDR This window displays the trace after one measurement. Definition of Trace: After one measurement, reflection power diagram will be displayed as distance function. This diagram is referred to as trace. Trace of OTDR displays measurement result in a graphic form. The y-axis stands for power, and the x-axis stands for distance, as shown in Figure 3-4. Reflection Attenua ...
