1751A 1550 nm DWDM DFB Laser Module

DATASHEET | JUNE 2012

FIBER OPTICS

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

Node Capability

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.
