摘要: This chapter will present different network and system solutions built on optical technologies discuss associated functionalities. The main focus be wavelength division multiplexing (WDM), which has initiated tremendous capacity increase, particularly in the transport area. First, however, some general aspects features of networks described. is then followed by a discussion WDM networking, where new elements are introduced. networking provides several options connectivity for given topology. choice pattern results amounts wavelengths required impacts complexity elements. basics patterns requirements discussed this chapter. Furthermore, protection switching within also elaborated, schemes presented with particular emphasis ring protection. Finally, various that useful important discussed.
