PDL/IL/DOP Multimeter - PolaCHEX™
|
|
Product Summary
Using a patented deterministic power search method (compliant with TIA/EIA-455-198),
General Photonics’ PDL multimeter measures the Polarization Dependent Loss (PDL),
Insertion Loss (IL), & optical power output of a device under test (DUT) in sub-seconds.
Unlike PDL meters that use a polarization-scrambled input to the DUT and look for the PDL
via output power fluctuations, PolaCHEX™ systematically searches for the maximum & minimum transmission,
assuring measurement accuracy at all times. Consequently, this instrument is the most accurate PDL meter
available on the market, able to accurately characterize devices with both low and high PDL values.
Even more impressively, PolaCHEX™ can cover a wide wavelength range from 1260 to 1650 nm without wavelength calibration-
a clear advantage over meters based on the Mueller Matrix method.
PolaCHEX™ comes with RS-232, USB, Ethernet, and GPIB interfaces for PC control, and is ideal for rapid,
accurate characterization of the performance of passive devices, especially DWDM components, in manufacturing environments as well as in laboratories.
