1754W 1550 nm DWDM DFB Laser Module
The 1754W laser module is a Dense Wavelength Division Multiplexing
(DWDM) laser for analog wireless applications. It features a distributed-
feedback chip that has been designed specifically for radio frequency
(RF) applications. The 1754W laser module 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 1754W is available in a wide range of standard ITU grid
wavelengths.

Absolute Maximum Ratings
DATA SHEET| JANUARY 29, 2008
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.

In order to prevent reflection-induced distortion, the laser must be connected to an optical cable having a return loss of at least 55 dB for discrete
reflections and 30 dB for distributed reflections.
