Notes:

1. Average launch power (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.
2. Transmitter Reflectance is defined as looking into the transmitter.
3. The receiver shall be able to tolerate, without damage, continuous exposure to a modulated optical input signal having this power level on one lane.
4. Average receive power (min) is informative and not the principal indicator of signal strength. A received power below this value cannotbe compliant; however, a value above this does not ensure compliance.
5. CAUI4 mode, the Pre-FEC BER level is 2E-4.
6. Measured with conformance test signal at TP3 for the BER specified in IEEE Std 802.3cd.
