Agilent 81480A and 81680A, 40A, 82A, 42A, & 89A Tunable Laser Modules Users Guide, Sixth Edition 25
The Agilent 81480A and 81680A/82A/40A/42A Tunable Laser
modules are back-loadable modules. To fit these modules into the
Agilent 8164A mainframe see “How to Fit and Remove Modules” in the
Agilent 8163A Lightwave Multimeter, Agilent 8164A, Lightwave
Measurement System, & Agilent 8166A Lightwave Multichannel
SystemUser’s Guide.
The Agilent 81480A and 81680A/82A/40A/42A Tunable Laser
modules have a built-in wavelength control loop to ensure high
wavelength accuracy. As these modules are all mode-hop free tunable
with continuous output power, they qualify for the test of the most
critical dense-Wavelength Division Multiplexer (dWDM) components.
The Agilent 81480A and Agilent 81640A/80A Tunable Laser modules
are equipped with two optical outputs:
Output 1, the Low SSE output, delivers a signal with ultra-low
source spontaneous emission (SSE). It enables accurate crosstalk
measurement of DWDM components with many channels at narrow
spacing. You can characterize steep notch filters such as Fiber
Bragg Gratings by using this output and a power sensor module.
Output 2, the High Power output, delivers a signal with high optical
power. You can adjust the signal by more than 60 dB by using the in-
built optical attenuator.
The Agilent 81682A/42A Tunable Laser module delivers a signal with
high optical power. If you choose Option 003, you can adjust the signal
by more than 60 dB by using the in-built optical attenuator.
