Getting Started with the Agilent 81600B Tunable Laser Source Family Typical Use Models
20 Agilent 81600B Tunable Laser Source Family, Fourth Edition
High Dynamic Range The low SSE output port delivers a signal with ultra-low source 
spontaneous emission. It enables accurate cross-talk measurement of 
DWDM and CWDM wavelength filtering components by producing light 
only at the desired wavelength.
For example, you can characterize steep notch filters such as Fiber Bragg 
Gratings by using the low SSE output and a power sensor module.
High Power For Agilent 81600B options 200, 160, 150,140 and 130, the second output 
port provides high optical power, adjustable over a power range of more 
than 60 dB via a built-in optical attenuator. 
The Agilent 81600B options 142 and 132 simply provide an output port with 
high stimulus power for applications where the SSE level is not critical. 
The 81600B option 142 can also be equiped with a built-in optical 
attenuator (option #003), so providing an adjustable power range of 60 dB. 
Precision Every Agilent 81600B Tunable Laser Source Family module includes a built-
in real time wavelength meter which realizes an absolute wavelength 
accuracy of ±10 pm (typ. ±3.6 pm) as a standalone instrument. 
Testing Integrated Optical
devices
The 81600B Tunable Laser Source Family’s PMF output ports provide a 
well-defined state of polarization to ensure constant measurement 
conditions for waveguide devices. A PMF cable easily connects to an 
external optical modulator.
