Abstract: The purpose of this application note series (Part 1 and Part 2) is to demonstrate by practical example how the laser properties can change over temperature, and how to compensate for these changes in order to maintain constant extinction ratio and average power in fiber optic transceivers. The application note you have requested is available in Acrobat PDF format: APPLICATION NOTE 1093: HFAN-02.3.2: Maintaining Average Power and Extinction Ratio, Part 2, MAX3863 Laser Driver and DS1847 Digital Resistor (PDF, 73kB) A free Acrobat PDF reader is available from: http://www.adobe.com/products/acrobat/readstep.html We Want Your Feedback!
