Product Description


GAOTek OTDR with Vision Fault Locating (Auto-Optimization) is an optical fiber communication tester which can test the length of optical fiber and optical fiber cable attenuation coefficient. It can display the loss distribution curve of the optical fiber and cable as well as the loss between two points and the joint loss. It can also test the distance between two points and the position of joint, fault point as well as breaking point.

The OTDR can be used in the fault detection of optical fiber cable and the construction and acceptance check of optical fiber cable project.


  • Test the distance between two points and dynamically display the distance between two cursors
  • Test the loss between two points and the loss constant of the optical fiber and cable
  • Test the joint loss
  • Auto-optimization and quick response
  • Search for the event points automatically
  • The function of waveform storage: it can store the waveform data and test condition into the disk and the stored information also can display again.
  • Support the function of copy: it can copy the data file which is built in the internal disk into the U-disk directly.
