title = "All-optical OFDM and distributed Raman amplification: Challenges to enable high capacities and extend reach",
abstract = "We review recent advances in all-optical OFDM technologies and discuss the performance of a field trial of a 2 Tbit/s Coherent WDM over 124 km with distributed Raman amplification. The results indicate that careful optimisation of the Raman pumps is essential. We also consider how all-optical OFDM systems perform favourably against energy consumption when compared with alternative coherent detection schemes. We argue that, in an energy constrained high-capacity transmission system, direct detected all-optical OFDM with ideal Raman amplification is an attractive candidate for metro area datacentre interconnects with 100 km fibre spans, with an overall energy requirement at least three times lower than coherent detection techniques.",
