Live Optical Signal Check Function

To have live Optical Signal Check Function,before a test pulse, First check test whether any of the optical fiber live communication optical signals and display the results.It can effectively protect test instrument and communications equipment.


Complete software support



  • Single page single tracing line or single page more tracing line can choose the print mode;

  • Batch change and batch print function;

  • Waveform difference contrast function;

  • Can be in the same window open multiple tracing line at the same time,the differences between the tracing line in the same window display and more easily compare such as optical fiber aging caused by the reasons changing parameters;

  • Bidirectional testing function.
