1.Optical time domain reflectometer product overview

The Optical time domain reflectometer is based on the time-domain reflectometer. It detects the length, loss, line connector, and break point of the optical fiber.6422Optical time domain reflectometer has the ability to test single-mode 1310nm, 1550nm, 1490nm, 1625nm, 1650nm, multi-mode 850nm, 1300nm and customized special wavelengths. It can provide a variety of modules such as single wavelength, multi-wavelength, online testing, etc., with a maximum dynamic range of 46dB, which can be used for long-distance multi-branch communication network testing of trunk lines; the minimum event blind area is 0.8m, and the connection status of the near end can be clearly distinguished; the maximum sampling resolution of 2.5cm can accurately locate the event 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 inspection instrument, WiFi module, etc.

2. Main features of optical time domain reflectometer

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

PON network online testing function;

Single-mode and multi-mode integrated testing function;

Communication light automatic monitoring function;

Supports Bellcore GR196 and SR-4731 file formats.

1. Fast and automatic testing

The automatic test function of 6422 makes it unnecessary for users to know more details about the operation of the instrument. The test steps become very simple. Users 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 test conditions and give the final test results, including test curves and event lists.

2. Unique PON network testing function

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

3. Automatic light detection and alarm function

When the OTDR tests a fiber link, if there is a communication optical signal in the fiber, the test result will be inaccurate, and even the detector inside the instrument will be irreversibly damaged. The 6422 has the function of automatically monitoring the communication optical signal in the tested fiber. As long as the tested fiber is connected to the optical interface of the 6422, it will automatically sense and monitor whether there is a communication optical signal in the fiber during the test phase. Once an optical signal is detected, an alarm message will be prompted 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 a graphical analysis of the current trajectory curve and display the graphical analysis interface.

5. Fiber end face inspection function

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