1751A 1550 nm DWDM DFB Laser Module

The 1751 laser module is a Dense Wavelength-Division Multiplexing

(DWDM) laser for analog applications. It features a distributed feedback

chip that has been designed specifically for Radio Frequency (RF)

applications. The 1751 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

versatile 1751 laser module reduces cable network architecture fiber

needs and lessens equipment reqirements in the hub.

Applications

The 1751 is available in a wide range of standard ITU wavelengths. The

lasers are offered as either forward-path (40 MHz- 860 MHz) or return-

path (5 MHz-210 MHz) modules.

Absolute Maximum Ratings

DATA SHEET| OCTOBER 25, 2004

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.
