Description 

TM70B PON Power Meter (pon test instrument) is specially designed for PON network construction and maintenance which can be connected between OLT and ONT. The voice, data, video signal (1310/1490/1550) online can be measured synchronously and optical power value (1310/1490/1550) can be displayed with this meter. It’s a useful site test tool for the engineers of PON network and maintenance operators.

 Main Features 

1.  Handheld, easy to operate 

2.  Can test 3 wavelengths’ power of PON system synchronously: 1310nm, 1490nm, 1550nm, 

3.  Can test the burst mode signal of 1310nm

4.  True color screen

5.  Friendly operation interface, human message management and operation function

6.  Supply 10 groups of threshold values for operator’s choice, analyze and display pass and fail status

7.  Relative value choice and edit function

8.  Can set the threshold value, upload data, and calibrate wavelength through management software

9.  Auto shut off (according to set value)

10. Auto backlight off(according to set value)

11. 6600mAh Lithium battery

12. Power saving design (Low voltage self check and power off)

13. Real-time clock display

14. Optical Power Meter （ Optional Function)

15. Visual Fault Locator ( Optional Function)
