2 Additional Features
Additional Features introduces additional features of the
Agilent Technologies E6000C Mini-OTDR (Optical Time
Domain Reflectometer). Here you will find descriptions of
how an OTDR works, and how you can add external
features to your Mini-OTDR.
How the OTDR Works
The OTDR repeatedly outputs an optical pulse into the
connected fiber and measures the reflections from this
pulse. The trace displayed on the screen is a graph of this
reflected power (backscatter) as a function of the distance
along the fiber.
