OTDR Measurement Function
|
Distance measurement
|
Displays up to eight digits of the relative one way direction between two arbitrary points on the trace.
|
Loss measurement
|
Displays one way loss in steps of 0.01dB to a maximum of 5 digits. Displays the one way loss, loss per unit length, and splice loss between any arbitrary points on the trace.
|
Return loss measurement
|
Measurement return loss and total return loss of a fiber cable or between two arbitrary points on the trace.
