4e - Save Insertion Loss Readings
When the test jumper and loopback are connected to the trunk fiber pairs, a live insertion loss
value will be shown on the power meter screen. This number represents how much light is lost
between the DLS 355 and VIS 300C OPM (up one side of the pair, through the loopback, and
back down the other side of the pair.)

Connect the test
jumper and loopback

save the reading for
each pair.
This box will appear. Touch
the text area to bring up
the keyboard and give the
