Description of Event Types

OTDR

101

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).

A loss value is specified for positive events. The loss specified does not
indicate the true loss of the event.

The true loss has to be measured by performing bidirectional fiber
measurements and bidirectional analysis.
