1.7 Multicore Loss Test (Option)
You can efficiently measure multicore optical fiber and optical line degradation. This feature is available
on AQ1200A models with the /SLT or /HLT option.
Master and Slave
Connect two AQ1200s and specify the optical power meter as the master and the light source as the
slave. You can also use the AQ1100 multi-field tester series instead of the AQ1200 as the master or
slave.
Specifying the Optical Communication Fiber
To transfer, between the master and slave, project setup information and information about the fiber
under loss test, you must specify a fiber from the multicore optical fiber to use for communication.
Connect one end of the optical communication fiber to the master’s light source port (optical port 2),
and connect the other end to the slave’s optical power measurement port (optical port 1).
Information That Is Transferred from Master to Slave
The following information can be transferred through the optical communication fiber from the
master to the slave.
• Project information (see below for further details)
• Loss test results
*
* Each time that the selected fiber’s loss test finishes, that fiber’s loss test result is automatically transferred.
Connecting the Optical Fiber under Loss Test
All fibers other than the optical communication fiber can be tested. For each optical fiber under
loss test, connect one end to the master’s optical power measurement port, and connect the other
end to the slave’s light source port. The core and tape numbers of the fibers under loss test are
transferred from the master to the slave.

Executing a Loss Test
Transmit light from the slave. The master will automatically identify different wavelengths in the light
from the slave and measure the optical power. Continue the loss test, switching the cores between the
master and the slave in order.
Projects
You can create projects with the master. You can specify the following project information:
The project name, the number of the core to start loss testing at, the tape number type, the number
of cores, and the transmitted or measured measurement light wavelengths (up to 2).
• You can transfer projects from the master to the slave and share information.
• When the master and the slave share a project and use that project to perform loss testing, if testing
is stopped, the data up to the stop point is saved and you can begin testing again from the next
core.
• You can save and load projects as CSV files.
