The Agilent 86120B—At a Glance
The Agilent 86120B—At a Glance
The Agilent 86120B Multi-Wavelength Meter measures the wavelength and
optical power of laser light in the 700-1650 nm wavelength range. Because the
Agilent 86120B simultaneously measures multiple laser lines, you can charac-
terize wavelength-division-multiplexed (WDM) systems and the multiple lines
of Fabry-Perot lasers.
What’s new with the Agilent 86120B
This book directly applies to Agilent 86120B instruments with firmware ver-
sion number 2.0. When first turned on, the instrument briefly displays the
firmware version. These instruments have the added capability of measuring
broadband devices and chirped lasers. Refer to “Measuring broadband devices
and chirped lasers” on page 2-10.
Characterize laser lines easily
With the Agilent 86120B you can quickly and easily measure any of the follow-
ing parameters:
• Wavelengths and powers
• Average wavelength
• Total optical power
• Laser line separation
• Laser drift (
wavelength and power
)
• Signal-to-noise ratios
• Coherence length
NOTE
The front-panel OPTICAL INPUT connector uses a single-mode input fiber.
