DUT and enter the desired settings (see below). Then press the ”Sin-gle Measurement” button or the ”Repeat Measurement” button. Bestperformance will be achieved in this mode.6.3.3 Measurement Raw DataRefer to Measurement Raw Data (section 6.2.8) to learn about how rawdata is embedded into the .pbin-files.6.3.4 Application Setup ParametersDefines the start of the wavelength sweep.Start wavelength (nm):Defines the stop of the wavelength sweep.Stop wavelength (nm):Defines the wavelength step size for the measurement.Step Size (nm):Defines the optical output power of the laser source.Laser Power (dBm):Shows the current gain setting of the input amplifieres (0=lowest sen-Current Gain:sitivity, 13=highest sensitivity). Each step changes the allowed opticalinput power range by approximately 3dB.Shows the estimated number of samples.Samples:If a reference measurement is done you can select whether it will be usedReference:for the measurement or not.Defines the width of the averaging window as well as data interleaving.Resolution (nm):Use smaller values for a better wavelength resolution.6.4 Application: PER/PMF CrosstalkUse this application for crosstalk measurements in polarization maintain-ing fibers (PMF). Typically the light inside a PMF has to be guided eitherin the slow or in the fast axis. Usually this can only be achieved to someextent and the signal inside the PMF can be divided into two componentsguided in the fast and the slow axis. The power ratio between these twocomponents is called polarization extinction ratio (PER). Typical valuesare between 20dB and 40dB meaning that the power in the ”wrong” axisis 20dB (40dB respectively) below the light in the desired axis.In case of limited PER the output polarization will move on a small-circleon the Poincar´e sphere when mechanically disturbing the PMF or whenchanging the wavelength of the source. The radius is a measure for thePER. This application measures the radius of the trajectory of the outputpolarization and calculates the PER. A laser source is used as stimulusand the trajectory can either be generated by continuously changing thesource wavelength or by disturbing the PMF (either manually or usingA1210 Thermal Cycling Unit).For details, please refer to the following sections:• Manual PER Measurement (PMF-stretching) (section 6.4.1)• Swept Wavelength Measurement (tunable laser source needed) (sec-tion 6.4.2)• Using a single A1210 Thermal Cycling Unit (section 6.4.3)• Using two A1210 Thermal Cycling Unit (splice alignment) (section6.4.4)• Using an FSM-45PM Fujikura PM Splicer (section 6.4.5)A1XXX/A2XXX/A3XXX User Guide 49
