Study Of Single and Multi Wavelength(WDM) EDFA Gain Control Methods
Journal Title: INTERNATIONAL JOURNAL OF ENGINEERING TRENDS AND TECHNOLOGY - Year 2013, Vol 4, Issue 5
Abstract
The purpose of this paper is to provide an introduction to EDFA and discussing various gain flattening techniques.EDFA is widely used amplifier due to its transient suppression, wide band variable gain operation. An amplifier should be dynamically configured over a wide range to support different span lengths. We focus on building dynamic reconfigurable optical layers to facilitate explosive growth in IP traffic. Wavelength selective switch devices provides dynamic configurability as we can add or drop the wavelengths at the nodes thus increasing network flexibility, improving bandwidth utilization and reducing complexity. Electronic feed-back control is designed for achieving flat gain at the top of required gain range. The paper begins with the basics of technology and then goes on to discuss gain fluctuation and various techniques for gain flattening for single and multi-wavelength system
