32-channel optical power machines

    The light of optical test frame structure as shown in figure 1 below,which need one set optical power meter,a light source and a controlling computer.If you want to test both the PDL indicators light taps,taps before a hand-operated type polarization controller,as shown in Figure 2.

    Open the control software, click on the " control " button in the drop down menu, select a port number, such as " 1x32 ", and set the corresponding control, including IL max, Uniformity and PDL max, as shown in Figure 2.

      After the devices connected, click on the " test " button, loss indicator will be displayed in a real time histogram form, 32 channel into two windows displayed, as shown in Figure 3. Dash for the index of the line of control, is not up to the index window, display the column as red, continue to adjust until until all columns are blue. Control and measurement indicators at the same time in the window on the left shows, is not up to the controlling index of items shown in red font.
