Bi-Directional Testing; Swapping Connections; Bi-Directional Autotest Results - Fluke DSP-FTA420 User Manual

Bi-Directional Testing

When you need to test fibers in both directions, the DSP-FTA4XX units can
perform bi-directional testing and save the bi-directional results for each fiber.
You enable this feature in the SETUP mode under BI-DIRECTIONAL
TEST.

Swapping Connections

To get bi-directional results for Smart Remote Mode, the test tool stops
halfway through a bi-directional Autotest and prompts you to swap the fiber
connections. Swap the connections on both the main and remote units.
To avoid disturbing the connections to DSP-FTA4XX output ports,
always swap the connections at the patch panel or adapter, not at the
DSP-FTA4XX connectors.
The test tool does not support bi-directional testing in Loopback Mode.
In Far End Source Mode, the test tool does not prompt you to swap
connections. If you need bi-directional results in this mode, swap the locations
of the test tool and the source; change the direction of the test (select A-B or
B-A under @ Options on the Far End Source Autotest display); then run
a second Autotest.

Bi-Directional Autotest Results

Bi-directional Autotest results list the test directions as A-B and B-A. In Smart
Remote Mode, "A-B" runs from the main unit to the remote; "B-A" runs from
the remote to the main unit. "Output Fiber" refers to the fiber that you
connected to the main unit's OUTPUT port after you swapped the fibers.
