Problem: 
How do I interpret the RL results graph on my Viavi 40G Certifier?
Solution: 
RL is Return Loss and measures the loss of reflected power. As we do not want a lot of reflected power, the greater the value (loss) the better the result. Y axis maps with a low value at the top and larger on the bottom so a passing result will graph below the limit line.
