Fiber Optics Communication

Fiber optics is the major building block in the telecommunication infrastructure. Fiber optic systems are important telecommunicationinfrastructure for world-wide broadband networks. Wide bandwidth signaltransmission with low delay is a key requirement in present day applications. Optical fibers provide enormous and unsurpassed transmission bandwidth with negligible latency, and are now the transmission medium of choice for long distance and high data rate transmission in telecommunication networks. This paper gives an overview of fiber optic communication systems including their key technologies, and also discusses theirtechnological trend towards the next generation.
