2 / 6 page DATASHEET| DECEMBER 29, 2007 EMCORE CORPORATION 1612A/B 1310 nm DFB Laser Module Absolute Maximum Ratings Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.
