“…For example, Dense Wavelength Division Multiplexing needs two-order of magnitude cost reduction to be applicable to the aggregation segment in 5G-Crosshaul [9], and this will only be possible by relying on new Silicon Photonics technologies for optical interfaces and switches. Together with existing, but deeply renewed, technologies, novel technologies will be considered by 5G-Crosshaul either to increase capacity and connectivity or to further reduce cost or power consumption: optical wireless technologies [10] and orthogonal frequencydivision multiplexing over fibre [11] are two examples of energy efficient solutions that can greatly enhance capacity and connectivity. Current deployment of OBSAI [12] or CPRI [3] for the fronthaul traffic is mainly using dark fibers to the Remote Radio Heads as other technologies do not meet the stringent requirements of latency (e.g., about 100 s for CPRI) and jitter (2 ppb).…”

“…The transmission of CE-OFDM signals in metro and/or longhaul optical links was considered in [8], [18], and [19]. The modulation scheme used in [8] enabled high signal powers in fiber links up to 1000 km of SSMF and eliminated the necessity of phase noise estimation and compensation procedures.…”

“…The approach proposed in [18] mitigated the degradation induced by fiber nonlinearities and inline dispersion compensation in link lengths of up to 800 km of SSMF. A potential deployment of the CE-OFDM transceiver based on fast Hartley transform was evaluated in [19], considering a practical network model that covers optical paths of up to 877 km. However, the results described in these works are based in numerical simulations and the constant envelope signals are generated with optical phase modulation.…”

“…In turn, the data rate is properly chosen depending on the demands at each node located across the network. The fixed grid due to its low flexibility and efficiency is being replaced by more dynamic solution with better and easier adaptation to the traffic congestion [Chochol12a,FabregaMch13c]. The shift from rigid optical networks based on fixed properties to spectrally efficient elastic optical networks with flexible bandwidth and adaptive channel spacing is observed.…”
