conduct the measurement.

When the test is complete, the results are displayed on screen, left to right, with
the last event usually taking place at the end of the fiber.
Note: Sometimes the end of the fiber (EOF) is not where it is expected due to poor
splices or cuts. EOF is the point where TRACETEK detects a large reflection
(about -14dB) which can be the actual EOF, a bad connector, or a break in the fiber.

Using the high resolution setting is best for cables under 800 m (2625 ft) in length.
The distance to the end of the fiber is displayed on the screen in the lower left-hand
corner of the display. The vertical cursor can be used to find the distance to an event
by moving it along the trace where the event is indicated. The distance to this point
appears on the screen in the upper right-hand corner of the display.
SAVING TRACETEK RESULTS
Like other tests, the resultant plot from TRACETEK can be stored in the LANTEK
handset and recalled or uploaded to a PC using the LANTEK Reporter software.
