Description
The A1614W 1310 nm wideband wireless DFB laser
modules are designed for anaolg applications requir-
ing an operational bandwidth between 100 kHz and
2700 MHz. The highly linear, OC-48 pinout-compati-
ble devices feature up to 16 mW output power with
superior performance over an enhanced operating
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 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.
