A1750A DWDM Analog
Forward-Path or Return-Path Laser Module
Description
The A1750A laser module is a dense wavelength-
division multiplexing laser with a DFB chip designed
specifically for analog RF applications. The device
features low adiabatic chirp to maximize signal qual-
ity in short and long lengths of fiber. The laser’s
excellent inherent linearity minimizes degradation of
the broadcast signals caused by the QAM channels.
Wavelength-division multiplexing (WDM) has gained
widespread acceptance in the telecommunications
market and is being designed into emerging cable
television network architectures. Dense WDM, a
method for delivering targeted QAM signals to differ-
ent locations, allows multiple signal sets to be com-
bined onto a single strand of fiber for transmission
from a headend to a hub. At the hub, individual QAM
signals can be selected and combined with broad-
cast analog channels. The A1750A DWDM laser
module reduces cable network architecture fiber
requirements and lessen equipment requirements in
the hub.
Features
■ Low adiabatic chirp
■ Excellent linearity
■ Standard ITU wavelengths
■ Advanced analog chip design
■ Tested for forward-path or return-path applications
■ Reduces equipment requirements in the hub
The A1750A is available at a variety of standard ITU
wavelengths. The lasers are offered as either for-
ward-path (40 MHz–860 MHz) or return-path mod-
ules (5 MHz–210 MHz).
■ Exceeds Telcordia Technologies* 468 specifica-
tion.
Applications
■ Networks with limited fiber
■ Architectures using separate optical wavelengths
to carry targeted services

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute 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.
