Otdr Fiber Tester

1.Overview of optical time domain reflectometer products

Otdr Fiber Tester is based on time-domain reflection measurement technology, which can detect the length of the optical fiber cable, loss, line connector, and fiber break point location.The 6422 optical time domain reflectometer has the testing capabilities of single-mode 1310nm, 1550nm, 1490nm, 1625nm, 1650nm, multi-mode 850nm, 1300nm and customized special wavelengths.It can provide single wavelength and multi-wavelength , online testing and other modules, with a maximum dynamic range of 46dB, which can be used for trunk long-distance multi-branch communication network testing; the minimum event blind zone is 0.8m, and the near-end connection status can be clearly distinguished; the maximum sampling resolution of 2.5cm can accurately locate events point.In addition, it provides a variety of convenient functional options such as stable light source, optical power meter, visible red light source, fiber end face inspector, and WiFi module.

2.Main features of optical time domain reflectometer

Maximum 46dB dynamic range, 256k data sampling points;

PON network online test function;

Single and multi-mode integrated test function;

Communication light automatic monitoring function;

Supports Bellcore GR196 and SR-4731 file formats.

1.Rapid automatic testing

The automatic test function of 6422 eliminates the need for users to know more details about the operation of the instrument.The test steps become very simple.They only need to connect the optical fiber to the corresponding OTDR port of the product and click the [Test] button.The instrument will automatically set the corresponding settings.test conditions and give the final test results, including test curves and event lists.

2.Unique PON network test function

6422 is a test instrument for optical fiber access network and FTTx.It has built-in PON network test function and can test each branch of the PON network through up to 1:128 optical splitter.

3.Automatic light monitoring and alarm function

When an OTDR tests an optical fiber link, if there is a communication optical signal in the optical fiber, the test results will be inaccurate and even cause irreparable damage to the detector inside the instrument.6422 has the function of automatically monitoring the communication optical signals in the optical fiber under test.As long as the optical fiber under test is connected to the optical interface of the 6422, it will automatically sense and monitor whether there are communication optical signals in the optical fiber during the test phase.Once an optical signal is detected, it will Prompt alarm information in time to provide timely protection for the instrument.

4.Intelligent graphic display function of optical fiber link events

Select the analysis mode switch button to perform graphical analysis of the current trajectory curve and display the graphical analysis interface.

5.Fiber end face inspection function

The instrument is equipped with the end face detection function.Click the [End Face Detection] button to enter the end face detection operation interface.
