Introductionure which is capable of delivering huge amounts of data in real-time over a wide area. Optical fiber has emerged as an excellent medium for such future networks in view of its tremendous bandwidth potential (around 50 THz). It is already being used as a transmission medium of choice by several telec

Optimizing Amplifier Placements: The Unequally-Powered Wavelengths Casetropolitan areas. These networks suffer from splitting, coupling, and attenuation losses. Since there is an upper bound on transmitter power and a lower bound on receiver sensitivity, optical amplifiers are usually required to compensate for the power losses mentioned above. Due to the high cost of

Wavelength Conversionenges and performance issues which need to be addressed in order to incorporate wavelength conversion effectively. A review/survey of the enabling technologies, design methods, and analytical models used in wavelength-convertible networks is provided.

Impact of Transmission Impairments on Network Performances source and destination nodes. The optical signal may have to traverse a number of crossconnect switches (XCSs), fiber segments, and optical amplifiers, e.g., erbium-doped fiber amplifiers (EDFAs). Thus, while propagating through the network, the signal may degrade in quality as it encounters cross

Conclusionscient algorithms were presented which significantly improved the cost-effectiveness of these networks. The non-ideal behavior of common physical devices was highlighted and incorporated into the study of network-control algorithms, leading to more realistic characterization of the performance of suc
