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| JANUARY 13, 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.

1. Tested in a 50 Ohm resistively matched system.
2. Eight channel loading with 10% OMI and 40 km fiber.
3. Measured at 42 MHz.
4. Measured at 553.25 MHz, 577.25 MHz, and 595.25 MHz.
All parameters at Beginning of Life (BOL) and IF = IOP, unless noted otherwise.
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.
