Abstract
There is general consensus that future optical networks are demanding for 100 Gigabit Ethernet (100GbE). The jump toward 100GbE must take care of cost and power consumption aspects determined by physical, technological issues of a 100 Gbit/s transmission. Electronic components and ICs are pushed to their limitation in terms of bandwidth and power requirement and, at the same time, photonic processing is still in its early stage. Novel techniques and approaches must therefore be devised in order to understand 100GbE feasibility perspectives. With these premises, the foreseen solutions for 100 Gbit/s communication will be analysed and their suitability for 100 GbE discussed.
Different technological solutions, including Single Carrier (SC) with Electrical Time Division Multiplexing (ETDM) and Polarization Division Multiplexing (PDM), Wavelength Division Multiplexing (WDM), optical Orthogonal Frequency Division Multiplexing (OFDM), will be addressed.. Modulation formats will also be considered together with transmission impairments as a function of the link acteristics.
