A1751A DWDM Analog

Forward-Path or Return-Path Laser Modules

Description

The A1751A laser module is a dense wavelength-

division multiplexing (DWDM) laser for analog appli-

cations. It features a distributed-feedback (DFB) chip

that has been designed specifically for radio fre-

quency (RF) applications. The A1751A laser module

has a wide temperature range for reliable perfor-

mance 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 linear-

ity minimizes degradation of the broadcast signals

caused by the quadrature amplitude modulation

(QAM) channels.

Wavelength-division multiplexing is being designed

into cable television architectures. DWDM, a method

for delivering targeted QAM signals to different loca-

tions, allows multiple signal sets to be combined onto

a single strand of fiber for transmission from a head-

end to a hub. At the hub, individual QAM signals can

be selected and combined with broadcast analog

channels. The versatile A1751A DWDM laser module

reduces cable network architecture fiber needs and

lessens equipment requirements in the hub.

Features

■ Higher temperature rating

■ Excellent linearity

■ Standard ITU wavelengths

■ Advanced analog chip design

■ Tested for forward and return path applications

■ Reduces equipment requirements in the hub

The A1751A is available in a wide range of standard

ITU wavelengths. The lasers are offered as either for-

ward-path (40 MHz—860 MHz) or return-path

(5 MHz—210 MHz) modules.

■ Exceeds Telcordia Technologies* 468 specifica-

tion.

Applications

■ Node capability

■ Narrow transmitter housing

■ Networks with limited fiber

■ Architectures using separate optical wavelengths

to carry targeted services
