Note 4: Average receive power (min) is informative and not the principal indicator of signal strength. A received power below this value cannot be compliant; however, a value above this does not ensure compliance. Note 5: PRBS at BER 10-12, ER=3.5dB Technical Data of F903-CD02-3N90-E (Rev 1.0) Page 5
