Selecting Auto Or Manual Otdr Mode - Fluke OF-500 OptiFiber User Manual

Fluke Networks recommends that you use launch and
receive fibers. You should also use launch/receive fiber
compensation to remove the effects of these fibers from the
OTDR measurements.
W
For testing cabling with angled physical contact
(APC) connectors, use only launch/receive fibers
with APC connectors at the end connected to the
cabling. Other connector types will cause large
reflections that may invalidate your test results.
Avoid using hybrid patch cords to connect to the
cabling under test. Connect the launch and receive
fibers directly to the cabling under test, using a
launch fiber with the appropriate connectors. This
provides the best measurement of the connectors
at the ends of the cabling. Hybrid launch fibers with
various connector styles are available from Fluke
Networks.

Selecting Auto or Manual OTDR Mode

You should use Auto OTDR mode when certifying
cabling with the OTDR.
From the HOME screen, press
OTDR or Manual OTDR from the popup menu.
In Auto OTDR mode, the tester automatically selects settings
based on the length and overall loss of the cabling. This
mode is the easiest to use, provides the most comprehensive
view of the events on the cabling, and is the best choice for
most applications.
Manual OTDR mode lets you change settings to optimize the
OTDR for displaying specific events. See the online help or
the Technical Reference Handbook for details.
