RMS spectral width is the standard deviation of the spectrum. 2. Even if th e TDP < 0.9 dB, the OMA ( min) must exceed this value. 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. The receiver does not have to operate correct ly at this input power. 4. Conditions of stressed receiver sensitivity test: a) Vertical eye closure penalty (VECP), each lane: 1.9dB
