Repeat steps 12 to 14 to execute the multicore loss test.
Explanation
This feature is available on models with the /SPM or /HPM option.
The same project conditions must be shared between the master and slave. The project conditions
can be shared using the following methods.
Sending Project Conditions
Send the project conditions from the master to the slave.
Decide in advance which optical fiber cable to use to transmit the project conditions (signal
transmission optical fiber cable). Before sending the project conditions, connect one end of the signal
transmission optical fiber cable to the OTDR port (PORT1) on the master side and the other end to the
OPM port on the slave side.
• On the slave side, prepare to receive the project conditions.
• On the master side, check that the slave is ready to receive the test conditions, and send the
conditions.
Note
When a project is sent, loss test results and skip information are not transmitted.
Loading a Project File
Load the same project file into the master and the slave. Have the project file stored in the internal
memory of the instrument or a USB memory device in advance.
Restarting an Interrupted Loss Test
In a multicore optical fiber cable loss test, you may need to interrupt the test before the loss tests have
been completed on all cores. If you want to resume the loss test using the same shared project, the
test can be resumed while retaining the data of the completed tests. Data is maintained even when
you turn the Instrument off.
• The loss test must be performed using the same project.
• If you reload the project file, the data of the loss test up to that point will be deleted and cannot
be recovered.
Optical Power Adjustment
Adjust the optical power of the light source as necessary. When you execute optical power adjustment,
the Instrument automatically identifies the optical power level and adjusts itself accordingly. Perform
optical power adjustment on the light source side.
• Press the Execute soft key to execute the optical power adjustment. When adjustment ends
normally, the Instrument returns to the previous screen. While adjusting, the word “Execute” on the
menu changes to “Abort.” All soft keys other than Abort will be invalid.
• When you press the Abort soft key, the optical power adjustment will be aborted. The word “Abort”
On the menu returns to “Execute.” The adjustment value returns to the previous value before the
execution.
• Connect an optical fiber that is no longer than a few meters. Make sure that the fiber is free from
dirt, scratches, bends, and other potential causes of optical degradation.
• The default adjustment value is set to the factory default value.
