The Portable PON optical power meter is a tester designed for design, operation and maintenance of FTTX network. The PON optical power meter is able to concurrently measure the optical power values of voice, data and video signals. It is an ideal choice for the construction and maintenance of FTTX network works. Features Providing simultaneous measurement at all three wavelengths on the fiber ( 1490nm, 1550nm, 1310nm ) Used in Burst mode measurement of 1310nm upstream Dual-port through the design, guarantee the full communication testing from the OLT to the ONT Three status LEDs represents different optical signal conditions of Pass, Warn and Fail respectively Easy to use, simply connect the fiber to read the results HD TFT color LCD USB communication port enables data transfer , easy and quick 200 measurement items can be saved in PON power meter or computer for data review. Through the background software setting threshold, upload data, calibration wavelength Auto power off function, and time settings on the device, the threshold setting
