ABSOLUTE MAXIMUM RATING
These values represent the damage threshold of the module.   Stress in excess of any of the individual  Absolute  Maximum  Ratings  can  cause   immediate  catastrophic  damage  to  the module even if all other parameters are within Recommended Operating Conditions.

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.
