Notes:

Average launch power, each lane (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.
Even if the TDECQ < 1.4 dB for an extinction ratio of 4.5 dB or TDECQ < 1.3 dB for an extinction ratio of < 4.5 dB, the OMAouter (min) must exceed this value.
Transmitter reflectance is defined looking into the transmitter
The receiver shall be able to tolerate, without damage, continuous exposure to an optical input signal having this average power level
Average receive power, each lane (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.
Receiver sensitivity (OMAouter), each lane (max) is informative and is defined for a transmitter with SECQ up to 1.4 dB.
These test conditions are for measuring stressed receiver sensitivity. They are not characteristics of the receiver.
