Description of Event Types

OTDR 129

End of Analysis

This event indicates that the pulse width used did not provide enough

dynamic range to get to the end of the fiber.

³ The analysis ended before reaching the end of the fiber because the

signal-to-noise ratio was too low.

³ The pulse width should therefore be increased so the signal reaches

the end of the fiber with a sufficient signal-to-noise ratio.

³ There is no loss or reflectance specified for end-of-analysis events.
