Run an Autotest as follows:
1.
Turn the test tool's rotary switch to AUTOTEST and turn on the remote (if
used). Let the DSP-FTA4XX units warm up for five minutes.
2.
Verify that the Autotest display shows the correct test standard, cable type,
and remote end configuration. You can change these selections in the
SETUP mode.
3.
Select patch cords of the same type as the fiber to be tested. Refer to
Figures 8, 9, and 10 for the number of patch cords required for your
remote end configuration. Clean all fiber endfaces.
If you wish, you can press @ Help to show how to make the fiber

connections. You can select the type of adapter in the SETUP mode. This
will be particularly helpful when testing Small Form Factor (SFF) links.
5.
Set the reference level if it has not already been set. (See "Setting a
Reference" on page 11.)
6.
Connect the test tool to the fiber cable as appropriate. Refer to Figures 8,
9, and 10.
To start the Autotest, press E.
7.
If you are using Far End Source Mode, select the wavelength that matches
the source; then press E. For other modes, the DSP-4000 test tool
automatically switches wavelengths during the Autotest.
8.
If bi-directional testing is enabled, the test tool stops halfway through the
bi-directional Autotest and prompts you to swap the fiber connections.
Swap the connections at the patch panel or link connector, not at the
DSP-FTA4XX ports.
