Cascaded transmission, packet switching and all-optical wavelength conversion for 40 Gbit/s RZ payload with 10 Gbit/s serial-bit label

The authors demonstrate a network node with two-hop transmission, packet switching and gating-controlled all-optical wavelength conversion based on highly nonlinear dispersion-shifted fibre and fibre Bragg gratings for a serial-bit labelled 40 Gbit/s RZ payload with an overall power penalty of less than 1.5 dB.
