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.

• Integrated single-.mode and multi-mode test;

• Automatic monitoring of optical communication signals.

• File formats of Bellcore GR196 and SR-4731 Supported

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 network test function, can penetrate an optical splitter of up to 1:128, and can be used to test each branch of the PON network accurately.

Automatic monitoring and alarm of incoming optical signals

When the OTDR is testing the optical fiber line, the optical communication signal in the optical fiber, if any, will lead to inaccurate test results and even unrecoverable damages to the detectors in the device. 6422 can monitor the optical communication signal in the optical fiber under test automatically. As long as the optical fiber under test is connected to the optical interface of 6422, the device can automatically sense and monitor whether there is optical communication signal in it. Once an optical signal is monitored, it will prompt an alarm in time, so as to provide the quickest and the timeliest protection for the device.
