E2500-Type 2.5 Gbits/s Electroabsorption Modulated
Isolated Laser Module (EM-ILM)
Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operations section of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
