Model 1772 DWDM High Power CW Source Laser
The 1772 laser component is characterized for use as a CW optical source in CATV and DWDM networks. The 1772 is dc-coupled with a built-in TEC, thermistor, and monitor photodiode. The device is mounted in a 14-pin, OC-48 pinout compatible butterfly package with the optical isolator mounted on the TEC. The 1772 incorporates a high efficiency coupling scheme to deliver 40 mW, 50 mW, and 63 mW of CW optical power. Performance Highlights

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.
