POLARIZATION MEASUREMENT SYSTEM- PolaWise™
|
|
Product Summary
PolaWise™ is an advanced polarization measurement system for accurate characterization
of all polarization related properties of light sources and optical materials.
Based on General Photonics’ patented magneto-optic polarization generation and analysis technology,
the PSGA-101-A is specially designed for fiber optic applications and can effortlessly accomplish multiple functions,
including polarization state generation (PSG), polarization state analysis (PSA),
polarization extinction ratio (PER) measurement, polarization dependent loss (PDL) measurement,
and polarization mode dispersion (PMD) measurement. Another attractive feature of the instrument
is its large flip-top LCD graphic display design, an industry first that allows large viewing area
on a compact, portable enclosure. Furthermore, a 2x20 character LCD is also included on the front panel
for easy operation of the instrument for applications that do not require a graphic display, such as PER measurement.
The instrument comes with an internal tunable laser for PDL and PMD measurement up to 10 ps.
It can also control tunable lasers from third parties via a GPIB port for measurement of larger PMD values.
The instrument also comes with a VGA port for use with an external LCD graphic display of the user’s choice.
PolaWise™: a wise instrument and a smart choice!

Notes:
1. Operating wavelength range may vary for different
measurements. Typically, for PMD and PDL measurements using the
JME method, the operating wavelength range is 1440 to 1590nm.
PMD and PDL measurements using either the Mueller Matrix or
Poincaré Sphere methods can cover 1300 to 1620nm. PER
measurements can also cover 1300 to 1620nm.
2. DOP measurement accuracy for C and L bands.
