Data Sheet, Rev. 4 June 2001 A1750A DWDM Analog Forward-Path or Return-Path Laser Module Description The A1750A laser module is a dense wavelengthdivision multiplexing laser with a DFB chip designed specifically for analog RF applications. The device 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 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 meth
