2.0 Introduction of OTDR
2.1 Purpose of Measurement
OTDR shows the back-scatter light power of the optical signal relative to the distance. With this information, the OTDR could
measure a series of important information of an optical fiber such as the quality of the line, distance of the line and etc.
2.2 Content of Measurement
Event position—a broken point or the end of the tested fiber.
Optical attenuation coefficient of a optical fiber.
Single event loss, such as the loss of a connection or a macro bending. Or the loss of a end-to-end line on the tested
optical fiber.
2.3 Analyze of Curve
OTDR can auto analyze a tested trace, the position process shows below:
Get the reflection events generated by connectors or mechanical splicer.
Non-reflection events(usually it is splicing points or macro bending).
End: the first point which the loss of it is over the threshold would be scanned as the end of a trace.
Events list: event type, loss, reflection and distance.
