Notes:
1. The minimum ***erage launch power spec is based on ER not exceeding 9.5dB and tran***itter OMA higher than 0.1dBm.
2. Even if the TDP < 0.75 dB, the OMA min must exceed the minimum value specified here.
3. The receiver shall be able to tolerate, without damage, continuous exposure to a modulated optical input signal h***ing this power level on one lane. The receiver does not h***e to operate correctly at this input power.
4. Vertical eye closure penalty, stressed eye J2 jitter, and stressed eye J9 jitter are test conditi*** for measuring stressed receiver sensitivity. They are not characteristics of the receiver.
