TriBrer APL-2 - OTDR Analysis: Type and Result

Attenuation
Loss
Reflectance
Analyse of the type and result shows the distance difference and power difference between marker A
and B.
The distance and attenuation between marker A and B
4 points event loss: marker a, A, b and B in 4 points
algorithm. Move the markers appropriately, the
difference between the LSA value in "a, A" and
"b, B" can be used to judge the loss more accurately.
A-B LSA loss: marker A and B in 2 points algorithm.
Calculate the difference between A and B by the LSA
slope.
2 points attenuation: calculate the real attenuation between
marker A and B, then unitized to the loss per kilometer, which
makes the noise interference larger.
A-B LSA attenuation: obtained after calculating the LSA
slope between marker A and B, and the attenuation is
relatively stable.
Reflectance: marker a, A and B in 3 points algorithm.
Set "a, A" in the flat position before reflection and set
B in the highest point of reflection to show the
reflectance value.
A-B ORL: the ORL value between marker A and B,
Total ORL: the ORL value in the entire circuit.
