Keysight N777-C Family
of Tunable Laser Sources
Introduction
The Keysight Technologies N777-C Family of Tunable Laser Sources offers the
full wavelength range from 1240 nm to 1650 nm with no wavelength gaps.
The N777-C tunable laser sources realize the cost efficiency and performance
required to test components for coarse and dense wavelength division
multiplexing (CWDM, DWDM, 100GBASE-LR4) and passive optical networks
(PON). Whether you need to verify the design of demanding optical components
or adjust more wavelength-selective switches per hour, or you simply need a
stable, tunable optical source, the N777-C family of tunable lasers offers a
suitable model.
All N777-C models are based on a common cavity and laser module design and
share a narrow linewidth, excellent long-term stability and low spontaneous
emission level. They are software compatible with the 8160xA and 81600B
lasers, the industry standards for more than a decade, but occupy 1 height-unit
less rack space.
The remote user interface on the instrument is accessible with just a web
browser, either via LAN or via USB connection. An optional touch-screen display
provides local operator access and displays current operating parameters.
Compared t
o the top line model N7776C, the N7778C value line models and the
N7779C basic line models offer additional price-performance options based on
output power, tuning speed, wavelength accuracy and repeatability.
Web User Interface
but no LAN?
Connect instrument
and PC via USB. The
instrument shows up as
a new drive: double-
click the shortcut on
that drive. This lets the
default browser open
an RNDIS connection
to the instrument: the
graphical user interface
appears. It’s as simple
as that!
