Data Sheet, Rev. 4 June 2001 A1751A DWDM Analog Forward-Path or Return-Path Laser Modules Description The A1751A laser module is a dense wavelengthdivision multiplexing (DWDM) laser for analog applications. It features a distributed-feedback (DFB) chip that has been designed specifically for radio frequency (RF) applications. The A1751A 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 caus
