Use this function to tell the converter to send fiber signals request to the other convert at end side. You can use this to
check whether the converter can communicate with partner converter. Once you click the Apply button, the converter will
send n signals and the results will be displayed below the configurable data. And make sure the partner converter also
supports the Loop Back reply function.
