Notes:

1.    Average optical powers hall be measured using the methods specified in TIA/EIA-455-95.
2.    Power budget is defined as the different between the Rx sensitivity and the Tx output power of the interface .
3.    Path penalty is intended as the power penalty of the interface between back-to-back and the maximum applied dispersion .
