The 1764 laser module is a Dense Wavelength Division Multiplexing (DWDM)
laser for analog wireless and distributed antenna system (DAS) applications. It
features a distributed-feedback (DFB) device that has been designed specifically
for radio frequency (RF) and wireless applications. The 1764 laser has a wide
temperature range for reliable performance in harsh node environments and
narrow transmitter designs. It also features low adiabatic chirp to maximize signal
quality in short and long lengths of fiber. The laser’s excellent inherent linearity
minimizes degradation of the broadcast signals caused by quadrature amplitude
modulated (QAM) channels.
The 1764 is available in all C-band ITU grid wavelengths.

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.
