Description of OTDR Event Types
Data Post-Processing Software 211
Launch Level
Launch Level
This event indicates the level of the signal launched into the fiber.
³ The figure above shows how the launch level is measured.
A straight line is plotted using least-square approximation to fit all trace
points in the linear area between the first and second detected events.
The straight line is projected toward the Y (dB) axis until it crosses the
axis.
The crossing point indicates the launch level.
³ <<<< in the events table indicates that the launch level is too low.
