PDL Multimeter - PolaCHEX™
Using a patented maximum and minimum search method (compliant with TIA/EIA-455-198), General Photonics’ PDL multimeter simultaneously measures the Polarization Dependent Loss (PDL), Insertion Loss (IL), and optical power of a device under test (DUT) in just 30 ms. Unlike PDL meters that use the polarization scrambling method, which has large measurement uncertainty, PolaCHEX™ systematically searches for the maximum and minimum transmissions to assure measurement accuracy at all times for devices with both low and high PDL values. It is therefore the most accurate PDL meter available. Even more impressively, PolaCHEX covers a wide wavelength range from 1260 to 1620 nm without wavelength calibration, a clear advantage over PDL meters based on the Mueller Matrix method. PolaCHEX comes with USB, Ethernet, GPIB and RS-232 interfaces for PC control and is ideal for fast, accurate characterization of the wavelength dependence of passive devices, especially DWDM and fiber sensor components, in manufacturing environments as well as in laboratories. The PDL-201 replaces the PDL-101, with higher measurement speed, larger measurement dynamic range, a better and brighter display, and the addition of an analog output port for easy integration in automated measurement stations.
