Product name：

DT-623 PON Optical Power Meter

Product description：

The new test instrument for FTTX/PON testing, DT-623PON optical power meter can test the whole process communication from OLT (optical line terminal) to ONT (optical network terminal).

System functions System parameters Technical Parameters Typical application

Simultaneous measurement and display of voice, data and video signals over BPON/EPON/GPON architecture

• Simultaneous testing of 1490nm, 1550nm, 1310nm wavelengths in PON systems

• Burst mode test for 1310nm upstream wavelength

• 1000 records can be saved, viewed, deleted in the device or in the machine software

• Set thresholds, upload data, and calibrate wavelengths through PC software

• Provides ten sets of threshold selections, three indicators visually display the status of the measured light path

•Automatic shutdown after 10 minutes of equipment/time setting
