Notes:

a.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.

b. Even if the TDECQ < 1.4 dB, the OMAouter (min) must exceed these values

Note:

a. 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.

b. Receiver sensitivity (OMAouter), each lane (max) is informative and is defined for a transmitter with SECQ of 0.9 dB.

c. Measured with conformance test signal at TP3 for the BER = 2.4E-4. e. These test conditions are for measuring stressed receiver sensitivity. They are not characteristics Of the receiver.
