------------------------------------------------- ABSTRACT The race for unprecedented bandwidth is on - and DWDM(Dense Wave-length Division Multiplexing) is opening the way. DWDM is the technology that allows multiple streams of data to flow in one optical fiber of optical communication network. DWDM is the key technology at the heart of new systems and networks that offers more bandwidth at less cost. Soon‚ DWDM promises to change bandwidth from a premium to a commodity item. DWDM: Networks‚ Devices‚ and

Chapter 1 Introduction 1.1 History of Free Space Optics Even though fibre-optic communications gained worldwide acceptance in the telecommunication industry‚ FSO communications is still considered relatively new. But optical communication‚ in various forms‚ has been used for thousands of years. The Ancient Greeks polished their shields to send signals during battle. In the modern era‚ semaphores and wireless solar telegraphs called heliographs were developed‚ using coded signals to communicate
