With the rapid development of Internet information technology,the traditional photoelectric conversion technology has to some extent been unable to meet the requirements of modern telecommunications transmission.Erbium doped fiber amplifiers(EDFAs)can directly amplify optical signals under the action of pump light,making them suitable for modern fiber optic communication.This article analyzes the basic principles of EDFA and explores the application and development trends of EDFA technology.
