Using patented maximum and minimum search techniques, Newport's new 2550P Series Degree of Polarization Meter can measure and display the Degree of Polarization (DOP) of a light source in real time with high accuracy and wide dynamic range. Other expensive polarimeters measure the DOP less accurately for low DOP sources, while polarization scrambler-based instruments are less accurate for high DOP sources. Surprisingly, Newport’s low cost DOP meter provides simple and accurate DOP measurements for both low and high DOP sources. It is ideal for DOP characterization of depolarizers and depolarized light sources, such as ASE, SLED, and pumps for Raman amplifiers. It can also be used to monitor optical signal to noise ratio (OSNR) and polarization mode dispersion (PMD) of optical signals, and measure the noise figure of optical amplifiers. Another attractive feature is that no calibration is needed for a wide operating wavelength range, including S, C and L band. Finally, the instrument also simultaneously measures the optical power of the light source under test, a feature attractive for measuring DOP power dependence and for ensuring that a good optical connection is made to the instrument. USB, RS-232, and Ethernet communication interfaces are included. FC/PC and FC/APC connector ...
