The supply current includes CFP2 module's supply current and test board workingcurrent.
Average launch power, each lane (min) is informative for 100GBase-LR4, not the principal indicator of signal strength.
The receiver shall be able to tolerate , without damage, continuous exposure to an optical input signal having this average power level
The average receive power , each lane (max) for 100GBASE-ER4 is larger than the 100BASE-ER4 transmitter value to allow compatibility with 100BASE-LR4 units at short distances
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 (OMA), each lane (max) is informative
Measured with conformance test signal at TP3 for BER=10-12
conditions of stressed receiver sensitivity test: vertical eye closure penalty for each lane is 1.8dB;stressed eye J2 jitter for each lane is 0.3UI; stressed eye J9 jitter for each lane is 0.47UI.
