GAOTek 3239C FTTH Fiber Optical Power Meter

The 10G PON power meter is suitable for traditional or next-generation PON network testing.

GAOTek- OPM- 138



The 10G PON power meter is suitable for traditional or next-generation PON network testing.

It can simultaneously measure the voice, data, and video signals on 1490 nm/ 1550 nm/ 1577 nm (downlink spectrum) and 1270 nm/1310 nm (burst mode uplink spectrum) optical fiber, the same screen displays the signal power of each of the 5 wavelengths, which enables the maintenance personnel to truly master the power value of the single wavelength optical signal on the line. It’s an ideal choice for PON network engineering, construction, and maintenance to detect and analyze optical fiber with an optional end-face detector and judge whether the signal power is up to the standard by threshold data set by the instrument itself.



  • 5-inch TFT color screen.
  • Compatible with EPON, GPON, and next-generation 10G-EPON/XG-PON power measurement functions.
  • 5 wavelength power value simultaneous measurement display.
  • The instrument can set the measurement threshold to determine the pass, warning, and fail state.
  • Support VFL and standard OPM module functions.
  • Data storage function up to 1000.
  • Optional end-face microscope tester.
