6.4.4 Application: PER/PMF Crosstalk (Using two A1210 Thermal Cycling Unit)Use this application for characterizing splices between two polarizationmaintaining fibers. In that configuration, two A1210 Thermal CyclingUnit are needed (one for each PMF).Connect the heating devices to the A1200 according to the followingsetup:FixedWavelengthLaser SourcePER AnalyzerLaser Output Polarimeter Input(SMF or PMF)Personal ComputerUSBA1200PMFGPIBGPIB(optional)A1210Thermal Cycling Unit #1ExpansionUSB12V PowerSupplyPMFA1210Thermal Cycling Unit #212V PowerSupplySpliceunderTestTo optimize the splice angle follow these steps:• Setup your device so that coherent light is guided through the PMF(e.g. turn on your laser diode or connect a tunable laser source tothe PMF).• Start the PER-application by double-clicking it.• If the Thermal Cycling Unit are both detected, the heater 1 andthe heater 2 should appear as ”off” in the ”Fiber Heater Status”area.• Enter the correct wavelength of the laser source• Click on ”Splice Align”• The first A1210 is starting the temperature cycle by heating upthe PMF (LED=red) and then cooling down the PMF again(LED=green). Then the device is turned off (LED=off). Afterthat, the second A1210 is doing a temperature cycle.• The number displayed on the screen is the current PER/Splice An-gle.6.4.5 Application: PER/PMF Crosstalk (Using an FSM-45PM Fujikura PM Splicer)You can use the A1200 PER-Analyzer in combination with a FujikuraFSM-45PM splicer to automatically optimize the splice angle. You willneed the following equipment:• Adaptif A1200 PER-Analyzer• 2 x Adaptif A1210 Thermal Cycling Units• Fujikura FSM-45PM Splicer (Firmware revision higher than 1.37)A1XXX/A2XXX/A3XXX User Guide 53
