Notes:
1) The optical power is launched into SMF
2) The receiver shall be able to tolerate, without damage, continuous exposure to an optical input signal having this average power level. The receiver does not have to operate correctly at this input power.
3) Average receive power, each lane (min) is informative and not the principal indicator of signal strength.
