Description of Event Types
OTDR 131
Positive Event
Positive Event
This event indicates a splice with an apparent gain, due to the junction of
two fiber sections having different fiber backscatter characteristics
(backscatter and backscatter capture coefficients).
³ A loss value is specified for positive events. The loss specified does not
indicate the true loss of the event.
³ The true loss has to be measured by performing bidirectional fiber
measurements and bidirectional analysis.
