Product Overview

6422 OTDR modules could deliver single-mode wavelengths of 1310nm, 1550nm, 1490nm,

1625nm, 1650nm and 1383nm, multi-mode wavelengths of 850nm and 1300nm. It provides

multiple optional modules, such as single wavelength, multi-wavelength and online test. With the

maximum dynamic range of up to 46dB, the device can be used for remote multi-branch

communication network test. It's designed with a minimum event dead zone of 0.8m which makes

the near connection easy to be supervised, and the lowest sampling resolution of 2.5cm which

enables it to locate the event point accurately. Additionally, the device is also designed with

multiple convenient functional options, such as stable light source, optical power meter, visible

red light source and fiber end face inspection tester.

Rapid automatic test

Due to the automatic test function of 6422, it's not necessary for the user to know more about

its operation. Connect the optical fiber and press the [Test] button. Then, the device will set the

optimum test conditions automatically, and finally output accurate test results, such as the test

curve and the list of events.

Unique PON network test

As a test instrument for fiber access networks and FTTx, 6422 is provided built-in PON
