*Note 1: 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.
*Note 2: Even if the TDECQ <1.4 dB, the OMAouter (min) must exceed these values.
*Note 3: Transmitter reflectance is defined looking into the transmitter.
*Note 4: 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.
*Note 5: 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.
*Note 6: Receiver sensitivity (OMAouter), each lane (max) is informative and is defined for a transmitter with SECQ of 0.9 dB.
*Note 7: Measured with conformance test signal at TP3 for the BER specified in IEEE Std 802.3bs clause 124.1.1.
*Note 8: These test conditions are for measuring stressed receiver sensitivity. They are not characteristics of the receiver.
