Keysight / Agilent 81680A Modular Tunable Laser

Features
  • Operates In The 1550 nm Band
  • Built-In Wavelength Control Loop
  • Mode-Hop Free Tunable
  • Polarization Maintaining Fiber
  • Low Spontaneous Emission

Description

The Agilent / HP 81680A Modular Tunable Laser operates in the 1550 nm band. This module, with its built-in wavelength control loop, boasts high performance. The 81680A is mode-hop free tunable with continuous output power. This product features Panda PMF output ports to provide a well defined state of polarization to ensure constant measurement conditions on waveguide devices. A PMF cable easily connects an external optical modulator.

The 81680A is equipped with two optical outputs. One output port delivers a signal with ultra-low source spontaneous emission (SSE). It enables accurate crosstalk measurement of dense-WDM system components with many channels at narrow spacing. The second output port provides increased optical power and allows adjustment by more than 60 dB through a built-in optical attenuator.


Product Family: 81681A, 81681-A, 81681 A

InstraView™ Equipment Inspection



Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
