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.
