Notes:

1) Average launch power (min) is informative and not the principal indicator of signal strength. A transmitter with launch power below
    this value cannot be compliant; however, a value above this does not ensure compliance.
2) The receiver shall be able to tolerate, without damage, continuous exposure to an optical input signal having this average power
    level.
