For a timing system node we would have only expected fiber power on the first, but Riccardo saw power on the first and fourth.  Matt writes about this:  "I agree with your observation and the conversion formula.  In general, I'm finding the RxPwr number on lane 0 is inconsistent or suspicious.".  (conversion formula is what we use for xpm: dBm=10*log(10)(val/1mW))
