Description
The A1612A/B 1310 nm forward-path DFB laser
modules are designed for both broadcast and nar-
rowcast analog applications. The highly linear,
OC-48 pinout-compatible devices f eature up to
31 mW output power with superior distortion perfor-
mance over an enhanced operating temperature
range of –40 °C to + 85 °C.
With 31 mW of output power, the A1612A/B module
enables transmission beyond 40 km, and a greater
number of optical splits. In addition, the wide operat-
ing temperature range increases the laser’ s reliability
even in the harshest environments.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the de vice. These are abso-
lute 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.
