25  Gbit/s per User Coherent All-Optical OFDM for Tbit/s-Capable PONs. Morosi, J., Hoxha, J., Martelli, P., Parolari, P., Cincotti, G., Shimizu, S., Wada, N., & Boffi, P. Journal of Optical Communications and Networking, 8(4):190, Optical Society of America, 3, 2016.
25  Gbit/s per User Coherent All-Optical OFDM for Tbit/s-Capable PONs [link]Website  abstract   bibtex   
We propose and test a coherent all-optical orthogonal frequency-division multiplexing (AO-OFDM) system, based on all-optical (de)multiplexing and coherent detection, for multiterabit per second (multi-Tbit/s) passive optical networks (PONs). The proposed approach allows us to greatly increase the downstream data rate per user and extend the standard single-mode fiber reach for future long-reach applications. The compliance with a next-generation PON layout is guaranteed thanks to the exploitation of cyclic arrayed waveguide gratings. Five-user transmission with 12.5 Gbaud quadrature phase shift keying modulation per user (125 Gbit/s downstream capacity per wavelength) over a more than 40 km link has been successfully demonstrated.
