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 instrument
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.
For further details on its features, application and specifications, refer to
the product datasheet available on www.keysight.com.
The new Keysight N7776C top line tunable laser source is designed to
reach best-in-class accuracy and sub-picometer repeatability in static and
swept operation for outstanding test efficiency.
With the product family's lowest spontaneous emission level, the N7776C
enables the validation of extremely deep filters. It also offers the best
wavelength accuracy in the family – enabled by its high-resolution
wavelength reference unit that provides real-time tracking and control and
includes a gas cell for excellent long-term stability and self-adjustment
capability.
The new N7778C value line tunable laser source offers a peak output
power of more than +12 dBm, at least 75 dB/nm above its spontaneous
emission level. It features a typical wavelength repeatability of ±1.5 pm at
two-way sweeps up to 200 nm/s. The N7778C's balance of features,
performance and price makes it suitable for cost-effective,
high-throughput manufacturing-floor component testing as well as for
coherent transmission experiments.
