The Keysight 86120B—At a Glance
The Keysight 86120B Multi-Wavelength Meter measures the wavelength and opti-
cal power of laser light in the 700-1650 nm wavelength range. Because the
Keysight 86120B simultaneously measures multiple laser lines, you can character-
ize wavelength-division-multiplexed (WDM) systems and the multiple lines of
Fabry-Perot lasers.
What’s new with the Keysight 86120B
This book directly applies to Keysight 86120B instruments with firmware version
number 2.0. When first turned on, the instrument briefly displays the firmware ver-
sion. These instruments have the added capability of measuring broadband devices
and chirped lasers.
Refer to “Connect the fiber-optic cable to the front-panel OPTI-
CAL INPUT connector.” on page 2-40 .
Characterize laser lines easily
With the Keysight 86120B you can quickly and easily measure any of the following
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.
