Page 65
OTDR Continuous optical fiber This event indicates that the selected sampling range is shorter than the fiber length. ● the end of the fiber was not detected because the analysis process ended before the end of the fiber was reached. ●...
Page 66
OTDR End of analysis This event indicates that the pulse width used does not provide a dynamic range sufficient to reach the end of the fiber. ● the analysis ends early before reaching the end of the optical fiber, which is caused by the low signal-to-noise ratio.
Page 67
OTDR Non reflective event This event is characterized by the sudden reduction of Rayleigh backscattering signal level. It can be seen that there are discontinuities on the downward inclined curve signal slope. ● this event is usually caused by fusion point, macro bend or micro bend in optical fiber. ●...
Page 68
OTDR Reflective event Reflection faults are displayed as spikes in the fiber curve. They are formed by a sudden break in the refractive index. ● reflection events cause a large part of the energy originally emitted to the optical fiber to be reflected back to the light source ●...
Page 69
OTDR Gain event This event indicates a fusion point with obvious gain phenomenon, which is due to the different backscattering characteristics (backscattering and backscattering capture coefficient) of the two parts of optical fibers at the joint. ● the loss value of gain event has been specified, but the specified value does not represent the actual loss of this event.
Page 70
OTDR Emission level This event indicates the level of signal transmitted to the fiber. ● the figure above shows how to measure the emission level. Using the least square approximation method, draw a straight line in the linear region between the first and second detection events to fit all curve points in the linear region.
Page 71
OTDR Optical fiber area This symbol indicates that there are no events in the fiber area ● the sum of all optical fiber areas included in the whole optical fiber curve is equal to the total optical fiber factory. The events detected are always different - even if they all contain multiple points on the curve.
Page 72
OTDR Merged reflection events This symbol indicates that the reflection event has been merged with one or more other reflection events. In the event table, the symbol also indicates the total loss caused by the combined reflection event. ● merged reflection events consist of reflection events. Only the merged reflection events are displayed in the event table, not the reflection sub events that make up it.
Page 73
OTDR events, this line should be drawn in the linear area after the last merged event. Then, extend the line in the direction of the first merged event. ● the total loss (△ dB) is equal to the power difference between the starting point of the first event (point A) and the point on the extension line just below the first event (point B).
Page 74
OTDR Reflection event (possible echo) This symbol indicates that the reflection event may be a real-time reflection or echo generated by another stronger reflection closer to the light source. ● in the above example, the transmitted pulse hits the third connector, is reflected back to OTDR and enters the optical fiber again.
