1612A/B 1310 nm DFB Laser Module
DATASHEET | MARCH 2013
FIBER OPTICS
The 1612A/B 1310 nm forward path DFB laser modules are designed for both
broadcast and narrowcast analog applications. The highly linear OC-48 pinout
compatible devices feature options up to 31mW of minimum optical output power
with superior distortion performance over an enhanced temperature range of
-40C to +85C.

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.
