OF-500 OptiFiber Certifying OTDR
Technical Reference Handbook
Event Types
The tester analyzes events on the trace and assigns a type to
each event.
Table 3-4 describes the events the tester can identify.
3-30
REFLECTION
A pulse of light reflected back to
the OTDR.
OTDR PORT
The tester’s OTDR connector.
LAUNCH EVENT
The end of the launch fiber.
RECEIVE EVENT
The beginning of the receive
fiber.
Event
Caused by a connector, tight bend, or crack in the fiber. Small reflective events may
actually be ghosts.
If the reflection is not caused by a connector, inspect the cable for tight bends or
damage. Use a visual fault locator to verify the fault.
The tester identifies the OTDR port connection and grades its quality, as shown on
the OTDR DETAILS screen. See “OTDR Connection Quality” on page 3-13.
The tester identifies these events if launch and receive fibers are connected and
LAUNCH COMPENSATION is enabled on the OTDR tab in Setup. See “Compensating
for Launch and Receive Fibers” on page 3-4 for more information.
