Product Overview
6422 OTDR can used to test single-mode wavelengths of 1310nm, 1550nm, 1490nm,
1625nm and 1650nm, multi-mode wavelengths of 850nm and 1300nm as well as customized
special wavelengths. It provides multiple optional modules, such as single wavelength,
multi-wavelength and online test. With the maximum dynamic range of up to 50dB, the device can
be used for remote multi-branch communication network test. It's designed with a minimum event
dead zone of 0.5m 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.
6422 OTDR is designed with an operating temperature and a storage temperature of -10℃
~50℃ and -40℃~70℃ respectively to meet both EMC requirements as well as vibration and
shock test requirements, a MTBF(θ
0
) of 6000h or above to ensure a high reliability, and a 75W
built-in Li battery to ensure an endurance for continuous measurement in the wild field.
Main Characteristics
A maximum dynamic range of 50dB, and 256k data sampling points;
Online test of PON network;
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.
