DATA SHEET
| JANUARY 29, 2008
ORTEL, A division of EMCORE
1754W 1550 nm DWDM 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.
