Quick automatic test

Automatic testing function allows users don't need to know more details about the instrument operation which makes test steps much easier. You only need to enter the automatic test interface, connect optical fiber to corresponding OTDR port, then click on the 【Test】 button, the instrument will automatically set the corresponding test conditions and test results are given including test curve and event list etc.

Automatic light detection and alarm function

When OTDR tests fiber links, the test results will be inaccurate if there are communication optical signals in the fiber. It can even cause irrecoverable damage to the detector inside the instrument. 6420B has the function of automatic monitoring of communication optical signals in the fiber under test. As long as the fiber under test is connected to optical port, it will automatically sense and monitor whether there is communication optical signals in the fiber in the test phase. Once the optical signals are detected, alarm information will be given in time to provide timely protection for the instrument.
