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.
