    Introduction:


    EEE 461: Optical Fiber Communication


    Welcome to this course on EEE 461: Optical fiber communication. It is almost unnecessary to mention the importance of optical fiber in modern communication sector.Fiber optic communication has revolutionised the telecommunications industry.Fiber optical communication enables telecommunications networks to provide high bandwidth high speed data connections across countries and the globe. This type of communication can transmit voice,video and telemetry through local area networks,computer networks across long distance. Optical fiber also offers low power loss, lost cost, lower attenuation, greater security.
