1.4 Multicore Loss Testing
Multicore optical fiber and optical line degradation can be measured efficiently.
You can measure optical loss with models with -SPM or -HPM suffix codes.
Master and Slave
Connect two AQ1100s and specify the optical power meter as the master and the light source as the
slave. You can also use the AQ1200 multi-field tester series instead of this instrument 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.

Explanation
Wavelength
The light receiving element of the optical power measurement section has a wavelength sensitivity
characteristic.Thisinstrumentmeasuresopticalpowermoreaccuratelybyadjustingthesensitivity
according to the specified wavelength. The measurable wavelength range varies depending on the
model.
Models with -SPM or -HPM Suffix Codes
The wavelength ranges and steps vary depending on the wavelength mode that you set in the
detailed setup screen. You can set the wavelength within the following ranges.
Wavelength Mode Range and Steps
Simple You can select from 850 nm, 1300 nm, 1310 nm, 1490 nm, 1550 nm, 1625 nm, and
1650 nm.
Detail You can set the wavelength to a value from 800 to 1700 nm in 1 nm steps.
CWDM You can set the wavelength to a value from 1270 to 1610 nm in 20 nm steps.
Models with -PPM Suffix Codes
You can set the wavelength to one of the following values.
1310 nm, 1490 nm, 1550 nm
Modulation Mode
On models with -SPM or -HPM suffix codes, you can set the modulation mode for optical measurement
to one of the following options.
CW (continuous light), 270 Hz, 1 kHz, 2 kHz
Unit
You can set the optical power display unit to one of the following options.
dB (relative value), dBm (absolute value), W (absolute value)
• Thefollowingprefixes are attached to W: m (10–3),μ(10–6), n (10–9), and p (10–12).
• TherelationshipbetweentheabsolutevaluesdBmandWisindicatedbelow.
PdBm = 10 × log (Pw× 103)
Where PdBm is the optical power in units of dBm and Pwis the optical power in units of W.
Reference
You can set a reference and display measured values as relative values (display their difference from
the reference).
• PresstheDREFsoftkeytomakethedisplayedmeasuredvaluethereferenceanddisplay
subsequent measured values as relative values. The unit will change to dB.
