PON optical power meter

Product introduction

Optical power meter refers to an instrument used to measure absolute optical power or relative loss of optical power through a section of optical fiber. In fiber optic systems, measuring optical power is the most basic, much like a multimeter in electronics; conventional optical power meters generally measure in the range of 780-1650nm.

In the FTTX/PON network, it is generally required to measure three wavelengths in the fiber at the same time, the 1490nm and 1550nm downstream wavelengths, and the 1310nm upstream wavelength. Then the professional PON optical power meter came into being.

The handheld PON optical power meter is a test instrument specially launched for FTTX/PON passive optical network testing. It uses a high-definition TFT color LCD screen and can be used to test voice, Synchronous measurement and display of data and video signals.

Power threshold can be set to provide pass, warning or fail status indication for each wavelength. It is an ideal choice for PON network engineering, construction and maintenance.

Product features

1) Filter measurement function, and test the corresponding power values of the three wavelengths of 1490nm, 1550nm and 1310nm in the PON system at the same time;

2) Used for burst mode test of 1310nm upstream wavelength;

3) Dual-port direct-through design, which can guarantee the whole communication from OLT to ONT during the test;

4) Pass, warning or fail Through instructions, 3 indicator lights visually display the status of the measured light path;

5)Easy to use, only need to connect the optical fiber to read the results;

6) High-definition TFT color LCD;

7) Data transfer via USB, convenient and fast;

8) 1000 records can be saved, viewed, and deleted in the device or upper computer software;

9) Set the threshold through the background software, upload data, and calibrate the wavelength;

10) Automatic shutdown function, and time setting and threshold setting can be performed on the device;

11) With the function of ordinary optical power meter.
