| Notes: 1. RMS spectral width is the standard deviation of the spectrum. 2. The normative lowest value of OMA for a compliant transmitter is ‘ Launch power in OMA minus TDEC, each lane (min)’ plus the actual value of ‘TDEC’, but with a value of at least ‘OMA, each lane (min)’ . 3. TDEC is calculated from the measured TDECm using the methods in 3.6. TDECm is measured following the method in IEEE 802.3 clause 95.8.5 using a 12.6 GHz bandwidth reference receiver for all lanes. 4. If measured into type A1a.2 or type A1a.3 50 um fiber in accordance with IEC 61280-1-4. | ||||||
