Techwin fiber optical otdr tester for online testing We will try our best to provide products similar to Yokogawa OTDR, Anritsu OTDR, EXFO OTDR, JDSU OTDR, Ideal Networks OTDR. Introduction and Function of OTDR TW3100E Automatic Measurement Mode: Only by selecting the measurement wavelength, the measurement parameters are automatically set, and the trace data is automatically saved and automatically analyzed. Multi-wavelength Measurement Mode: In the parameter setting, the wavelength can be automatically switched into the multi-wavelength measurement mode. Under this mode, the analysis can be achieved on the attenuation state of the same fiber section under different wavelengths. Trace Fixing Function: It can achieve the same-screen comparison and display of one trace with another real-time trace or the trace under the average measurement, which is very useful for the installation of multi-core fiber or the checking of the aged fiber in the optical fiber network already been installed. Multi-wavelength Analysis Function: It can achieve the comparison, display and analysis functions of any trace file. Below are some specifications for OTDR TW3100E. Linearity (dB/dB) : ±0.05 dB/ dB Loss threshold (dB) : 0.05 Loss resolution ratio (dB) : 0.01 Sampling resolution ratiom: 0.125 to 8 Sampling point : 32K Distance uncertainty (m) : ±(1 m + 510 -5 distance + sampling interval) Distance scope (km) : 0.3 to180 Typical real-timerefreshing duration (s) : 0.2
