Optical Communications and Networking

Optical communications networks are enhancing a vital role such as there is high demand for capacity links. DWDM which means dense wavelength division multiplexing is widely organized at the core networks to deliver high capacity transport systems. Optical components such as, tunable filters, termination devices, optical amplifiers transceivers, and add-drop multiplexers are becoming more trustworthy and affordable. Access network and metropolitan area networks are progressively built with optical technologies to overcome the electronic blockage at network edges. Subsystems and new components for very high speed optical networks offer a new design options. Free-space optical communication has been arranged in space, while terrestrial forms are naturally limited by weather, geography and the availability of light.
