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.

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.
