Description of Event Types

OTDR 131

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.
