Product Description


GAOTek OTDR with Vision Fault Locating (Various Test Mode) plays an important role in modern telecommunication and CATV networks. As the requirements of the construction, test and maintenance of fiber optics become more prominent this device will be used regularly on the field. This OTDR is widely used in engineering construction, maintenance test and emergency repair of all fiber optics related systems.

Moreover, compared to regular OTDR, this instrument is more compact in size and easier for field use due to its lightweight and easy to carry features. The device has colour display and data storage capabilities and with the use of its USB interface the test data can be uploaded to the PC which facilitates the post-processing, archiving and printing.


  • Multiple light outputs, FC as standard ST/SC optional and exchangeable
  • Viewer software for data analysis, edit and printing.
  • 8m event blind zone, simple test of fiber patch cord
  • 1625nm wavelength, with belt filter, support FTTx online test
