We review recent advances in all-optical OFDM technologies and discuss the performance of a field trial of a
2Tbit/s Coherent WDM over 124km 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 ~100km fibre spans,
with an overall energy requirement at least three times lower than coherent detection techniques.
