SK321X PON Optical Power Meter

SK321X PON optical power meter is able to simultaneously test and estimate the signals of the voice, data and video. It is an essential and ideal tool for the construction and maintenance of the PON projects.

Key Features

Support the experiment at voice, data and video signal synchronous measurement and display on BPON/EPON/GPON

Providing simultaneous measurement for all three wavelengths on the fiber (1310nm, 1490nm, 1550nm)

Used in Burst mode measurement of 1310nm upstream

Use the software connect with computer setting the threshold, data transfer, and calibration the wavelength

Data storage and USB communication port enables data transfer to computer

Up to 10 different threshold sets in total

Three status LEDs represent different optical signal conditions of Pass, Warn and Fail respectively

Button design, high sensitivity, greatly reducing the volume and weight of the tester
