1764 1550 nm C-Band DWDM DFB Laser Module

DATASHEET | JULY 2013

FIBER OPTICS

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.

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.
