1.5 Light Source and Optical Power Meters
(Options)
The features listed for the loss-measurement light source and optical power meters are available on
models with the /SLT, /HLT, or /PPM option. The features listed for the visible light source are available
on models with the /VLS option.
Loss-Measurement Light Source
The following measurement light wavelengths can be generated.
Model Measurement Light Wavelength
AQ1200A SM 1310 nm, SM 1550 nm
AQ1200B SM 1625 nm
AQ1200C SM 1650 nm
AQ1200E SM 1310 nm, SM 1550 nm, SM 1625 nm
AQ1205A SM 1310 nm, SM 1550 nm
AQ1205E SM 1310 nm, SM 1550 nm, SM 1625 nm
AQ1205F SM 1310 nm, SM 1550 nm, SM 1650 nm
You can produce continuous light or light that has been modulated at the selected frequency (modulation
mode).
Visible Light Source
You can produce visible light to visually identify breaks in the optical fiber under test. You can turn the
visible light on and off independently of the measurement light source.
Optical Power Meter
The two instrument types listed below are available for measuring different types of optical power.

1 Wavelengths can be set with the wavelength mode set to Simple, Detail, or CWDM.
• Simple: You can select from a list of preset wavelengths.
• 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 along the CWDM
wavelength grid.
