Architectural tradeoffs for reconfigurable dense wavelength-division multiplexing systems

摘要: Advances in optical technology now allow practical reconfigurable wavelength networks to be constructed. These use wavelength-switching components dynamically route wavelengths, and provide a level of flexibility scalability previously not possible. Other such as low-noise amplifiers, electronic dispersion compensators, advanced modulation techniques simplify system operation, increase capacity, extend reach. From an application perspective, the architecture transport is evolving based on requirement support higher bandwidth access infrastructure. The network also needs incrementally expand basis customer demand key features broadcast lower cost video services. development new architectures for how these are influenced by critical parameters emerging component technologies reviewed
