LC Polarization Maintaining Patch CordPolarization jumpers have orthogonal "slow" and "fast" axes with different propagation constants. There is little coupling between the polarization modes,Website:://.zgtech-solution.com, therefore, light launched on one axis would propagate on that axis. It features high extinction ratio as a result of very accurate active alignment between PM Major axis and the connector key. Various PM fiber and connectors are available.Performance SpecificationParametersUnitvaluesConnector Type FC/UPC, SC/UPC, LC/UPCFC/APC, SC/APCKey orientation Slow axisAxis alignmentdeg.3°Wavelengthnm<980* 1060* 1310 1480 or 1550Maximum Insertion LossdB0.5Typical Insertion LossdB0.40.5Optical Return LossdB>=50>=60Extinction RatiodB>=25Maximum Optical Powermw300Fiber Length ToleranceOperation Temperature° C-5 to 75Storage Temperature° C-40 to 85* Typical insertion loss 0.1dB higher for shorter wavelengthsOrdering informationPMJwavelengthconnectorCable typeCable lengthFiber type 9=980 10=1060 13=1310 14=1480 15=15501=FC/UPC 2=FC/APC 3=SC/UPC 4=SC/APC 5=SpecialB=900um buffer C=3mm cable1=1.0 m 2=special1=Panda fiber
