Hands-On High Capacity Optical Networks: ROADM, DWDM, CWDM, COHERENT OPTICAL SYSTEMS & RAMAN AMPLIFICATION Fundamentals, Technology, Tests and Current Issues
Course Description:
WDM technology (Wavelength Division Multiplexing) has revolutionized the telecommunications market in the whole world by offering a phenomenal cost-effective increase in the fiber transmission capacity. DWDM (Dense WDM) became commercial in 1995 while CWDM (Coarse WDM) emerged after 2000, stimulated by the telecom crisis. CWDM brings simpler technological concepts as compared to DWDM, cutting down prices, but fits just the lower transmission capacity markets, such as the metro and enterprise networks.
More recently, new paradigmatic revolutions have made their way into the optical communication market ROADM (Reconfigurable Optical Add-Drop Multiplexing), Raman Amplification and Coherent Optical Systems. While these optical technologies are the perfect solutions to satisfy the growing demand for bandwidth they also provide radical cost reduction in the information transmission market.
