GAOTek High Precision OTDR Optical Fiber Measurement Tool

This high precision otdr optical fiber measurement tool has <19.68 ft, <13.12 ft attenuation, 0.01 dB threshold loss, and 0.001 dB resolution loss.




  • Automatic Measurement Mode Only by selecting the measurement wavelength
  • Multi-wavelength Measurement Mode In the parameter setting
  • Multi-wavelength Analysis Function It can achieve the comparison display and analysis functions of any trace file
  • FT Tx online testing, able to identify the splitter and the fibre’s end
  • Large-capacity lithium-ion rechargeable battery
  • Connection State Detection to promptly know the connection status of the instrumentation and the fiber for test.
