Note：
1、Average optical power shall 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.
