*Note 1: The receiver shall be able to tolerate, without damage, continuous exposure to an optical signal having this average power level. The receiver
does not have to operate correctly at this input power.
*Note 2: 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 3: Measured with conformance test signal at TP3 for the BER specified in IEEE Std 802.3-2018 clause
*Note 4: Receiver sensitivity (OMA
outer
), each lane (max) is informative and is defined for a transmitter with a value of SECQ up to 3.4 dB.
*Note 5: Ceq is a coefficient defined in IEEE Std 802.3-2018 clause 121.8.5.3 which accounts for reference equalizer noise enhancement.
