Function introductionAutomatic measurement mode: There is no need to select the measurement distance and measurement pulse width. The system will automatically predict the length of the optical fiber line, automatically select the appropriate measurement range and measurement pulse width, and the trace can also be automatically saved or manually saved, which is convenient for data analysisMulti-wavelength measurement mode: In the parameter setting, you can choose to use the dual-wavelength test mode. The system will automatically switch the wavelength for measurement, so that different measurement wavelengths can be used for loss calculation in the same section of fiber for data analysis.Multi-trace analysis function: It can realize the comparison and display analysis and calculation between any trace files, and up to 4 traces can be displayed at the same timeLarge-capacity lithium-ion polymer battery: long standby time, can be used for long-term measurementOnline optical detection: can effectively protect test instruments and communication equipmentDual operation mode: pure screen touch operation or pure physical button operation can realize all functions, which is convenient for engineers with different usage habitsData analysis: The device can save and generate standard curve files (.sor), with a storage capacity of more than 20,000It is easy to realize the printing of analysis reports and printing of curves to facilitate project acceptanceTechnical specificationsPulse Width(SM 1310/1550NM) 5ns, 10ns, 20ns, 50ns, 100ns, 500ns, 1μs, 2μs, 5μs, 10μs.(MM 850/1300NM) 5ns, 10ns, 20ns, 50ns, 100ns, 500ns, 1usDistance range(SM 1310/1550NM) Dead zone test, 1.3km, 2.5km, 5.0km, 10km, 20km, 40km, 80km, 120km(MM 850/1300NM): 100m, 400m, 1.3km, 2.5km, 5km, 10km, 20km, 40km, 80kmSampling resolutionMinimum 0.05
