1260-1620 nm; DOP Accuracy 0.2%, 0.5%; DOP Range 0-100%; DOP Resolution 0.01%; Operating Power Range -40-6dBm General Photonics’ DOP-201 system measures and displays the degree of polarization (DOP) of a light source in real time on the front panel display. The instrument incorporates a patented maximum & minimum search technique that accurately measures both low and high DOP with a wide dynamic range. This technique is superior to polarimeter-based methods that are inaccurate at low values of DOP as well as scrambler-based methods which are less accurate at high values of DOP. The instrument's wide wavelength range includes the S, C and L bands, without calibration. Simultaneous measurement of DOP and optical power level of the light source under test can be used to obtain DOP power dependence and to ensure low insertion loss during depolarizer manufacturing. The DOP-201 degree of polarization meter is ideal for characterizing the performance of depolarizers and depolarized light sources, such as ASE and SLED sources and the pumps for Raman amplifiers. It can also be used to monitor the OSNR (optical signal-to-noise ratio) and PMD (polarization mode dispersion) of optical signals, and to measure the noise figure of optical amplifiers. The DOP-201 features fast measurement, high accuracy and resolution, a wide operating power range, a bright OLED display and an analog output port for easy integration in automated depolarizer manufacturing stations. Key Features: Rapid Measurement Speed: 30 ms Degree of Polarization (DOP) Wavelength Independence High DOP Accuracy: ±0.5% for Single Sample, ±0.2% for 10 Sample Average Wide Operating Wavelength Range: 1260 to 1620 nm DOP Range: 0 to 100% DOP Resolution: 0.01% Operating Power Range: -40 to 6 dBm Front Panel Real-time Display Analog Output Dimensions: 356 x 216 x 89 mm Applications: Characterizing Depolarizers and Depolarized Light Sources, Such as ASE and SLED Sources and the Pumps for Raman Amplifiers; Monitoring OSNR and PMD of Optical Signals; Measuring the Noise Figure of Optical Amplifiers; Depolarizer Manufacturing and QC; Fiber Gyro Coil Characterization; ROADM Manufacturing
